Abstract:

Heavy metals polluted soils are a significant worldwide environmental problem. The crops cultivated in polluted soils often contain significant levels of heavy metals (Cd, Pb, etc.) that can impair human health. The current technologies such as removing up of pollutants, stabilization/solidification of pollutants, vitrification, soil capping, etc., used in remediation of polluted soils are not adequate. Smarter and cheaper techniques still to be addressed to decontaminate polluted soil. In the present study, nanotechnology has been adopted to immobilize heavy metals in polluted soil, in which nano-particles; nano-scale zero valent iron, bentonite-nZVI, nano alginite, nano carbon and dendrimers are used as immobilizing agents. Six soil samples collected from different locations in Egypt which have been polluted by either sewage sludge, industrial wastes, or vehicle exhausts, are treated with nano-immobilizing agents, at three rates of 0.1, 0.5 and 1%. The treated soil samples are incubated for two months which were subjected to eight wetting and drying cycles. At the end of the incubation period, the soils were analyzed for the determination of total, plant available as extracted using DTPA solution, and various chemical fractions of Cd and Pb. The results showed that all nano-immobilizing agents proved high efficiency to reduce the level of DTPA extractable-Cd and Pb. The magnitude of the reduction varied as both agent and rate of application varied. The efficiency of the tested nano-agents to immobilize Cd and Pb increased as the rate of application increased. The sequential extraction experiment showed that, nano immobilizing agents successfully altered Cd and Pb from mobile to immobile form as the exchangeable Cd and Pb significantly decreased in all tested soils, whereas, carbonate- and oxides- bound-Cd and-Pb significantly increased. Also, the results of the pot experiment showed that application of nano-materials to polluted soils at rates of 1% and 2% significantly increased fresh and dry weight of crop Garden Rocket (Eruca sativa) and decreased uptake of Cd and Pb.

Abstract:

Volcanogenic Massive Sulphide (VMS) deposits are typical Cyprus-type and occur in the Oman Ophiolite as clusters of pyritic copper-rich mounds with gold bearing gossans. The occurrence of deposits is abundant in Sohar–Shinas region of East Al-Batina coast region of the Sultanate of Oman. This work describes the spectral absorption characters of the minerals of the deposits and demonstrates the methods to map the deposit. The spectral absorption character of minerals namely epidote, chlorite, pyrophyllite, illite, calcite, dolomite, pyrite, siderite and hematite are studied and the image processing methods namely band ratios, principal component analysis (PCA), spectral angle mapper, linear spectral unmixing (LSU) and spectral feature fitting (SFF) were applied to map and discriminate the minerals and rocks of the deposits using Landsat 8 and ASTER data. The results of study evaluated in the field to show the sensor capability potential of the image processing methods.

Abstract:

To distinguish different SRSF environments, detailed measured sections, their comparison and correlation are essential. Unchannelized outer fan deposits display simple, parallel bedding of high lateral continuity. Mid-fan channels exhibit complex bedding patterns with vertical and lateral random distributions of channel fills, axial erosion, bed convergence towards the channel margins and linear bed continuity. Only outer fan beds can be laterally correlated on a local to regional scale. Inner fans/fan valleys are rarely exposed. Fan environments can further be distinguished by (1) different turbidite facies associations: mainly B, C and D in outer and A, B, C, D, and channel margin facies in middle fans, (2) greater average bed and layer thicknesses in mid-fans than in outer fans, (3) more frequent amalgamations in channel fills than in outer fans, (4) more frequent tabular amalgamations in outer fans, (5) more frequent nontabular amalgamations in mid-fan channels, and (6) more frequent dish structures in mid-fan channels. Fan valley fills comprise coarse conglomerates. In their vicinity mud-rich basin slope deposits may occur. SRSFs occur in restricted continental basins, either isolated or as coalescing fans. Lateral fan extent often measures close to 25 km with thicknesses usually Ë‚300 m. Their shape in plain view (radial, curved) depends on the basin floor slope. SRSF formation is closely related to tectonics. Their sand is immature, deriving from nearby sources and transported by short rivers with a steep gradient. Tectonics provide for narrow shelves, making SRSFs relatively insensitive to sea-level changes. Submarine canyons may intercept sand from longshore drift and/or rivers and funnel it to the fans.

Abstract:

East Java area carbonate contributes significant oil production for Indonesia with production around 145 MBOPD (18% national production) and next year will contribute around 240 MBOPD (30% national production). Based on the seismic section from North to South, shows Kujung Reservoir in Northern area of East Java shallower than the Southern areas. Implication of this morphology, Northern part have been exposed with good reservoir properties, such as in West Madura offshore indicate patch reef morphology with intensive vuggy porosity. When transgressions happened at the end of Kujung Formation, Southern part carbonate experiencing drowning and can’t grow up, but northern part Kujung Formation still grow up. Subsurface modeling in Northern and Southern area required different method. Northern area, focused on using seismic attributes that can detect hydrocarbon potential, such as AVO that used for mapping hydrocarbon potential in each patch reef. Southern part, the focus is for interpreting reservoir properties with Amplitude impedance. For production performance, Southern part produces more than Northern part. Dimensions of build-up reef in Southern area is quite large with connected pressure (pressure maintenance are applicable). One well in northern part can be produced with initial production 300–1,000 BOPD, cumulative production 500–800 MBO. Southern part one well can be produced 7,000–14,000 BOPD with cumulative production 17,000–20,000 MBO. Because of the unique carbonate system, detail evaluation is needed on geological conditions, reservoir characterization, and production analysis of East Java carbonate, so it could be a reference for developing other carbonate reservoirs in other area.

Abstract:

A group of intrusive and extrusive igneous rocks are located south of Wadi Abu Ziran, central eastern desert. These rocks have diverse petro-graphic compositions ranging from gabbros to granites with their volcanic equivalents. They belong to four distinct Neoproterozoic units of the eastern desert, namely; “metagabbros (MG), older granites (OG), metavolcanics (MV) and younger granites (YG)”. Both major and trace elements are compiled to deduce their genetic relationships. 1/Sr vs. Rb/Sr and Rb/Ba vs. Rb plots suggests that these rock units exhibit comparative magmatic relationships. The trace elements data and the numerical modeling are treated according to the general equation of partial melting and Rayleigh equation of fractional crystallization. These rock types favor complex petro-genetic processes during their generation. The magmatic model is based on “in-sequence” genesis between partial melting and fractional crystallization as well as magma mixing processes in the late stage. It is evident that these rocks are resulted from five essential stages during magmatic evolution of the area; the gabbroic rocks (MG) were derived by partial melting (42.5-45.93%) of oceanic crust followed by fractional crystallization (30-50%) of the resulted ultramafic magma; rocks of granodiorite (OG) were derived throughout partial melting (30-39.47%) of gabbroic parent followed by (55-80%) fractional crystallization of gabbroic magma; the metandesite (MV) was generated throughout partial melting (0.4%) of granodiorite (OG) followed by fractional crystallization (25-50%); the monzogranite (YG) was derived throughout (3-6.02%) partial melting of granodiorite (OG) followed by (40-65%) fractional crystallization of granitic magma, finally; the recorded hybrid granodiorite rocks (YG) were generated by partial melting of both gabbroic rocks (MG) (29.58%) and granodiorite (OG) (6.02%) followed by magma mixing and (35-60%) fractional crystallization.

Abstract:

A total of 23 soil samples were collected from the scattered agricultural farms along the Gulf of Aqaba coast. In addition, 25 granitic and marine sedimentary samples were collected from the study area. Following their treatments by total digestion technique, these samples were analyzed for different metals (such as Pb, Ni, Zn, Co, Cr, Mn, Fe, Hg, Mo, and Cd) using the inductively coupled plasma. Relationships among these metals for the study area were then examined by correlation analysis, principal component analysis, and hierarchical cluster analysis. Results from correlation analyses reveal a variable degree of correlations among different metals in the study area. Principal component analysis identified two factors, which are responsible for ~60% of the total variance of the data set. These two factors allowed to group the selected metals according to their geochemical features. Hierarchical cluster analysis classified the studied metals into different groups based on the similarity of their characteristics. The level of metal contamination in the study area has been assessed using enrichment factor and geoaccumulation index, showing relatively high percentage of enriched metals in the study area. The studied rock samples show a significant variation in mean metal contents from one rock type to another, but their results are in good agreement with those obtained from soil samples. High concentration of Cd in the studied soil samples is mainly due to extensive use of fertilizers and pesticides in the agricultural farms or due to sewage.

Abstract:

Gibbsite sediments occur in Abu El Mogherat area, located about 40 km to the east of Abu Zenima town, Southwestern Sinai, Egypt. These sediments occur as a blanket or karst on the surface of the Lower Carboniferous Um Bogma Formation. Kaolinite, goethite, hematite, alunite, quartz, REE minerals (Bastansite and Cerianite) and accessories bearing REEs and radioactivity (xenotime and zircon), celestite, barite, chalcophanite, lithiophorite and coronadite beside concentrations of some base metals as Cu, Zn, Pb and Ni are associated with gibbsite. The studied gibbsite is relatively enriched in Al2O3, Fe2O3, MnO, Co, Ni, Cu, Zn, Pb, Cd, As, Bi, W and U. The REE content (341 to 5111 ppm) shows a relative enrichment in LREE than HREE. The chemically analyzed U (Uc) and its radiometric equivalent (eU) in Abu El Mogherat gibbsite are estimated to be 345 and 281 ppm, respectively. This suggests a disequilibrium state. The high content of U and its disequilibrium state besides the almost complete absence of Th, suggest secondary supergene enrichment of U.

Abstract:

The upper part of the Adediya Formation (Cambro-Ordivician) exposed in southwestern Sinai represents a very interesting succession. It contains mineralizations which are exceptionally rich in radioactive and rare earth elements as well as heavy metals. Field and several laboratory studies were carried out on this part of the Adediya Formation exposed in four stratigraphic sections distributed in a geographically wide area in southwestern Sinai. The radioactive mineralizations exist in sandstones, ironstone bodies and, to a much lesser extent, siltstones. Each of these rock types has a relatively wide range of textural characteristics. The recorded mineral assemblage consists of a large number of essential and accessory minerals some of which are radioactive and REE-bearing. The obtained field and laboratory data were implemented to determine the sedimentary history of the host rocks and the genesis of the mineral species which constitute the mineralizations. This included the identification of the types and effects of the various diagenetic processes and hydrothermal activity which led to the genesis of the recorded mineralizations. Also, the relative roles played by these post-depositional processes in determining the mineral, chemical and radioactive characteristics of the mineralizations and host rocks were assessed. These roles resulted in redistribution of the various elements especially the radioactive and rare earth elements as well as heavy metals during the epigenetic phase particularly by the action of supergene processes. A genetic model for the studied mineralizations is proposed.

Abstract:

Palaeozoic, Mesozoic and Cenozoic black shales that can be a potential source of energy and precious metals are widely distributed in Malaysia Peninsula, Sarawak and Sabah. These black shales cover wide range of geological ages as well as sedimentological settings. Palaeozoic black shales outcrops were reported in West Malaysia and range from Cambrian to Permian. Some of these black shales were deposited in tidal environment as indicated from the associated HCS sandstone and abundance of burrows. Triassic black shales both in West and East Malaysia associate the turbidites. Paleogene black shales outcrop in West Malaysia with coals beds suggesting deposition in delta environment. The Neogene black shales outcrop in East Malaysia either as non-marine black shales associated with coals beds or marine turbidites with sandstones. Mineralogical investigations indicated variations among the studied black shales. Although illite was identified in almost all black shales, other clay minerals show significant variations. Some of the studied black shales are composed entirely of illite, while others show abundance of kaolinite. Smectite has been reported only in the drop stone of the Devonian-Permian Singa Formation. The compositional variations among the studied black shale can be attributed mainly to the variations in the source rock composition and the study localities used to receive sedimentary supply from a local source(s).

Abstract:

This work is an extended literature review about the evolution of Martian exploration. For instance martian exploration experienced a noticeable improvement in terms of methodology and reached findings. Mars exploration may be conducted based on different types of missions: Remote sensing, independent landers, networks, penetrators, rovers, balloons, airplanes, and samples return missions. Our knowledge about the red planet has significantly increased. As a synonym for Mars' geology, the term areology (from the Greek word Arēs, i.e. Mars) sometimes appears in the popular media and works of science fiction but the term is rarely, if ever, used by professional geologists and planetary scientists. Divided into different sub-disciplines, martian geology argues full similarity with the field of terrestrial geology. As a sign of remarkable proliferation, the term Mars geology fully incorporates all branches of terrestrial geology such as geophysics, geochemistry, mineralogy, geodesy, hydrology, hydrogeology, tectonics, geodynamics, climatology, cartography, sedimentology, and stratigraphy. In the Arab word, few are the studies dealing with Mars. In this vein, Emirate Mission to Mars is a first ambitious notice. Nonetheless, this mission should be well integrated within the state of the art of areology to provide with relevant data helping in understanding the as yet unsolved issues. In addition, it should target the site candidate to contain the most relevant geological and potential biological processes. Our recent work presents Argyre basin as a prime target for in situ Astrobiological Exploration of Mars. For this reason, I propose the Argyre basin as target site of Emirate Mission to Mars.

Abstract:

A comprehensive geochemical study shows genetic relationships among 15 crude oil samples recovered from different formations, ages of marine carbonate and non-degraded. The levels of maturation are relatively varied for each sample from low to moderate, sourced from Jurassic age. Various oil fields in South Iraq; Al-Fakka (FK-2, FK-3 & FK-8), Buzerkan (BU-11, BU-20), Abo Gharab (AG-1, AG-7 & AG-10), Halfaya (HF-1 & HF-2) and Amara (AM-3) oil fields. These samples suggest the ages and paleo-environments of their source rocks. The samples were collected from Jurassic to tertiary reservoirs of 15 developed oil fields where about 15 billion barrels of recoverable oil have been reserved. The oil density varies in rather wide range, between 12.2 and 39.2_API. Twelve oil samples are ˂25o API referring to heavy oil and only oil samples recovered from Hf-1, Am-3 and Bu-11 which are 25-35o API are medium oil. Canonial Variables (CV) according to the Tissot and Welte’s classification (1984), most of the oils can be classified as “high sulfur” oils/indicate that these samples are of marine origin. Stable Carbon Isotope Composition C15+ saturate and aromatic is relatively approximate values giving good supporting evidences for the same family which is Middle Jurassic Age (sourced from Sargelu Formation), generated within the sedimentation of the bituminous calcareous shale and Limestone in Mesopotamian basin extends from North-South Iraq. This basin consider as one of the most formative, potential and promising basin in the Middle East according to the typical total petroleum system elements. This family was generated by marine carbonate-intra shelf sub basin source rocks, occurring in Jurassic-Cretaceous-Neogene reservoir rocks in both Zagros fold belt and Mesopotamian basin which are geochemically similar to the extracts from Middle-Upper Jurassic age (Sargelu and Naokelekan formations), yielding the majority of petroleum oil and gas fields in north and south Iraq.

Abstract:

The Kouambo iron deposit with a typical banded iron formation is located in the northwestern margin of the Congo craton. The BIFs are hosted in Palaeoproterozoic Nyong series, a dominantly metasedimentary formation, and were metamorphosed into greenschist to amphibolite facies. The Kouambo BIFs belong to oxide facies iron formations and are characterized by fine- to medium-grained, very well banded and consist of alternating of Si-rich and Fe-rich mesobands. Geochemistry analyses reveal that these iron formations have a very simple chemical composition, with Fe2O3T and SiO2 representing more than 96 wt.% of the average composition; suggesting chemical precipitates of silica and iron. Moreover, these BIFs have low concentrations of Al2O3, TiO2 and HFSEs (high field strength elements, e.g., Zr, Hf, Ta, Pb and Th), suggesting that terrigenous detrital materials contributed insignificantly to the chemical precipitation. The PASS-normalized REE-Y patterns display minor LREE depletion and HREE enrichment, positive Y anomalies similar to seawater-like signature. However, they display weak positive Eu and negative Ce anomalies, a primitive chondrite-like “CHARAC” signature (23

Abstract:

The correct pore pressure data has important impact in oil gas activities. Besides preventing hazardous compounds, the availability of pore pressure data also contributes in reducing the operation cost. This paper presents the overview of the pore pressure behaviors which will reflect in changes of thermophysical properties since these thermophysical properties are dependent on pore pressure. This is also related to the heat flow across the earth whereas it is a function of thermal conductivity and temperature gradient in a conductive environment. The purpose of this empirical study is to carry out and investigate the relationship of pore pressure and the thermophysical properties in the subsurface for pore pressure estimation. These studies consist of laboratory experiment and data analysis for producing the model of pore pressure changes in hydrocarbon production from thermophysical sides. Different fluids saturation is used for illustrating the hydrocarbon production. This concept will form the basis for a new approach in pore pressure estimation.

Abstract:

The major rock units in the Wuyo-Gubrunde Horst, northeastern Nigeria are gneisses, porphyritic granite, altered granite, sheared granite, basalts and sandstone. Uranium has been reported in rhyolite and sheared rocks within the area. Petrogenetic evolution of the uranium-mineralized granitoids and associated rocks in the area were evaluated in the light of new geochemical data, which showed that uranium mineralization is within the altered granite rock and hydrothermal related. The granitoids are metaluminous, sub-alkaline, S-type granite that evolved by partial melting of crustal material emplaced at moderate depth of 20-30 km in a syn-to late-collisional within plate tectonic setting. The negative Eu/Eu* anomaly and higher (La/Yb)N ratio of the granitoids are indicative of magma fractionation. The lower SiO2 (<53%) and higher Fe2O3 (10%) of the altered granite compared to other similar rock units suggested pervasive alteration. The associated basalts are tholeiitic, emplaced within continental plate and enriched in Ni (122 ppm), V (169 ppm), Nb (39 ppm), Sr (570) and Light Rare Earth Elements (LREEs). The uranium content, P2O5, Fe2O3, TiO2, MnO, Co, Nb, Sr and V of the altered granites are higher while the Na2O, K2O, SiO2, Th and Rb contents are lower than those of the other rock units in the area. This supported hydrothermal source for the uranium mineralization. The basaltic rocks have similar SiO2, Fe2O3, V, Th and Co contents with the mineralized altered granite suggesting rock-fluid interactions and element mobilization. The uranium mineralization in the area was through secondary enrichment, hydrothermally sourced and remobilized by induced post-magmatic volcanic events.

Abstract:

The Mahshahr city is exposed to a wide variety of pollutants due to the presence of various environmental polluter sources. The aim of present work is the assessment of concentration and source of heavy metals, as well as polycyclic aromatic hydrocarbons (PAHs) in the dust streets of Mahshahr city. In this way, dust street samples were collected from areas with different utility (e.g., industrial, commercial, educational, high traffic, hospitals, residential, and park). After sample preparing, heavy metals concentration like, Sb, Pb, Zn, Cu, Co, Cr, Mn, Ni, Mo, V, Fe and PAHs were measured using ICP-OES and GC-MS analyses respectively. The average values of enrichment factor for Fe, Cu, Zn and Pb is intermediate. Calculation of geoaccumulation index (Igeo) indicate that heavy metals such as Fe, Cu, Zn and Pb in the dust samples belong to contaminated to medium contaminated categories, while other heavy metals (i.e., Co, Sb Cr, Mn, Ni, Mo, and V) belong to uncontaminated class. Statistical analyses such as principal component analyses (PCA) and clustering analyses (CA) was used to assess the natural and/or anthropogenic origin of pollutions. The results of these analyses indicate that heavy metals and polycyclic aromatic hydrocarbons mostly originated from anthropogenic sources, owing to the presence of petrochemical industries, and vehicles traffic. PAHs with high molecular weight (HMW) are dominant in all selected dust street samples. Also, it is confirmed that PAHs in dust have a pyrogenic origin. Importantly, the sum of carcinogenic PAHs in all sampling sites is higher than sum of non-carcinogenic PAHs. The ratios of IND/(IND+BghiP) vs. (BaA/(BaA + Chr) proved that biomasses, together with oil and coal combustion could be considered as the source of PAHs in the dust street samples of Mahshahr.

Identify the rock lithology has important meaning for estimating the reserve of petroleum as reservoir capacity and storage ability. The lithology identification from well log based on not conventional cross plot proposed and studied, which is more easier instead of rock core data observation results. However, this work carried out comparison between manual chart and analytical solution of matrix parameters (ρma and ΔTma) estimation values of producer Shaly sand reservoir, and present the main depositional environment affects. Incompatible and compatible cross–plotting between measured wire line data recorded over than 750 feet produced Upper Nubian Sandstone belong to two oil fields, SE Sirt Basin. Rock physics and petrophysics are studied for specific purposes to understanding the relationships between rock physics parameters and lithology. Consequently, variety of matrix parameters values is contributed by different clay minerals present in this reservoir type. This Shaly reservoir divided into three main units (R, E and F), and each unit has been subdivided into three subunits (F3, F2, F1, E3, E2, E1, R3, R2 and R1) from bottom to top according to depositional and petrophysical properties.

Abstract:

Thirty water samples from open and bore-wells were collected during the post-monsoon period 2015, in parts of Alladurg area of Medak district to assess the quality of water for both drinking and irrigation purpose. The suitability of the water from the groundwater sources for drinking and irrigation purposes was evaluated by comparing the values of different water quality parameters with World Health Organization guideline values for drinking water. In connention to that different parameters like pH (6.7–7.8), Electrical Conductivity (400–2600 mg/l), Total Dissolved Solids (256–1664 mg/l), Total Hardness (85–540 mg/l), and major cations [Na+ (0–19.09 mg/l), K+ (1.17–30.03 mg/l), Ca2+ (20.04–170.34 mg/l), and Mg2+ (6.08–96.06 mg/l)] and anions [CO3−(0–231 mg/l) HCO3− (122–719.8 mg/l), Cl− (17.72–730.27 mg/l), SO4− (15.84–213.12 mg/l), F− (0.25–2.8 mg/l), and NO3− (7.83–484 mg/l)] were estimated and calculated various indices like Sodium Absorption Ratio, Sodium Percentage, Residual Sodium Carbonate. HCO3− and Ca2+ were the dominant ions in groundwater samples and also major hydrochemical facies were Ca–HCO3, and Ca–Mg–Cl types. Majority of the samples are suitable for drinking purposes except fluoride and nitrate and far from drinking water standards. The results showed that the high fluoride concentration is southern region while high nitrate concentration zone was middle part of the study area. Based on the US Salinity Laboratory diagram, groundwater samples were classified as C3S1 (>80%) and C2S1 were the most dominant classes in groundwater samples are due to high concentration of bicarbonate. The groundwater quality is above the sufficiency level for both drinking and irrigation, and appropriate management measures are recommended for sustainable development.

Abstract:

Non symmetrical azimuthal resistivity survey was applied with three different types of electrode arrays: Wenner, Schlumberger and polar dipole-dipole in two sites near water well contaminated with hydrocarbon materials in Karbala governorate for delineating underground seepage of contaminated water. A subsurface plume of contaminated water was detected moving to northeast direction. It is found that all the used arrays show the ability to delineate the contaminated water plume but polar dipole-dipole array was the best to delineate the exact axis of that plume. Symmetrical azimuthal resistivity survey with Wenner electrode array was applied in four stations near contaminated well 8 in order to detect moving direction of contaminated water spill from the well. This technique gave good results in detecting spill direction where the major amount of spill moving from the well towards northwest direction, then the spill divided into two parts; major part moving to northeast direction and the second part moving to southwest. Azimuthal resistivity techniques can be successful in detecting contaminated water spill under proper conditions. Deep VES survey (maximum distance between current electrodes was 800 m) in four VES points was applied in order to study the deep hydrocarbon contaminant-bearing layer (layers) with respect to its depth and thickness in its actual deep position. It is found that VES technique is not effective to detect this hydrocarbon contaminant-bearing layer (layers) in its actual position at the surveyed area, whereas the boundary between Dibdibba and Injana formations and the depth to the upper boundary of Dammam formation were detected.
