Abstract:

Petroleum in Precambrian deposits, including giant oil and gas fields are discovered in many parts of the world. In East Siberia, the major petroleum occurrences are related to Lena-Tunguska petroleum province, where the total reserves of gas are estimated to be about 6-7 trillion m3, and that of oil are about 1 billion tons. The most prominent feature of the Precambrian oil is its unusual carbon isotope composition, which varies in the range of the δ13C-values between -32 and -37‰, while the majority of world's oils occurring in Fanerozoic deposits are characterized by the δ13C-values from -27 to -29‰. Chemical composition of the Siberian Proterozoic oils is also distinctive. The peculiar hydrocarbon chemistry and unusual carbon isotope composition are characteristic of many Precambrian oils in the world. We show that geochemical specificity of the Precambrian oil is related to their origin predominantly from bacterial material, and bacterial kingdom proliferates in periods of intensive volcanism that may explain correlation of oil occurrences in Precambrian with times of active volcanism. We observed two types of Precambrian gases in East Siberia. The first type is gas generated from kerogen at the late stage of its catagenesis. The East Siberian gases with δ13C-values from -28 to -32‰ may have such origin. The other type of gas, which δ13C-values from -35 to -43‰ originates from destruction of high molecular hydrocarbons at the end of the “oil window’ stage, when formation of gas-condensate begins. We believe that petroleum in Precambrian is most likely to be secondary product of destruction of the initial oil deposits.

Biography:

Can Rao has completed his PhD from Nanjing University and Post-doctoral studies from Nanjing University. He is one of Associate Professors of Zhejiang University. He has found 3 new minerals (strontiohurlbutite, minjiangite and mengxianminite), which have been approved by IMA, and published 16 papers in reputed journals.

Abstract:

Mengxianminite, Ca2Sn2Mg3Al8[(BO3)(BeO4)O6]2, is a new borate mineral from Xianghualing skarn, Hunan Province, southern China. It occurs in the Hsianghualite vein from this skarn, and is associated with fluorite, phlogopite, hsianghualite, magnetite, tourmaline, magnesiotaaffeite-2N2S and calcite. Mengxianminite forms subhedral to euhedral green crystals from 20 to 200 μm long, translucent to transparent, with a vitreous luster. The crystals show perfect cleavage on {100} and good cleavage on {010}, and do not fluoresce in long- or short-wave ultraviolet light. The estimated Mohs hardness is 8, and the tenacity is brittle with irregular fracture. The calculated density is 4.17 g/cm3. Optically, mengxianminite is biaxial (–), with α = 1.80(2), β = 1.83(2), γ = 1.84(2) (589 nm). Chemical analysis by electron microprobe (average of 6) gave Al2O3 40.00, SnO2 25.96, MgO 6.57, CaO 8.56, FeO 4.83, B2O3 6.52, BeO 4.68, ZnO 1.81, MnO 1.23, Na2O 1.13, TiO2 0.10, SiO2 0.04, sum 101.42 wt%. The empirical formula, calculated on the basis of 26O, 2Be and 2B atoms per formula unit, is (Ca1.63,Na0.39)Ʃ2.02(Sn1.84,Zn0.24)Ʃ2.08(Mg1.74,Fe0.72,Al0.38,Mn0.19,Ti0.01)Ʃ3.04Al8 [(BO3)(BeO4)O6]2. The stronger eight lines of the powder XRD pattern [d in Å (I)(hkl)] are: 3.000(35)(16 20); 2.931(100)(17 11); 2.475(29)(022); 2.430(30)(13 31); 2.375(100)(14 02/640); 2.028(52)(21 31); 1.807(35)(913); 1.530(98)(14 60/15 33). Mengxianminite is orthorhombic, space group Fdd2; unit-cell parameters refined from single-crystal X-ray diffraction data are: a = 60.689 (3), b = 9.907 (1), c = 5.740 (1) Å, V = 3451.0 (3) Å3, Z = 8. The structure of mengxianminite is composed of alternating O-T1-O-T2-O’-T2 layers stacked along the a axis, equal to two alternating modules: A module (O-T1-O) consists of the spinel modular and another O layer (AlO6 octahedra layer); B modular (T2-O’-T2) shows the simplified formula CaSnAl(BeO4)(BO3), SnO6 octahedra are isolated in the T2 layers, connected via BeO4 and CaO11 groups; AlO6 edge-sharing octahedra in the O’ layer form chains running along the b axis; these chains are connected in the c direction by the BO3 triangular groups. Mengxianminite is of hydrothermal origin, crystallized during the late stage of the xianghualing skarn.
