英文摘要: In the Tarim Basin, black shale series at the bottom of Cambrian is one of the important marine facies hydrocarbon source rocks. This research focuses on the analysis of the isotope of noble gas of 11 cherts. The R/R(a) ratio of chert in the Keping area is 0.032-0.319, and (40)Ar/(36)Ar is 338-430. In Quruqtagh the R/R(a) ratio is 0.44-10.21, and (40)Ar/(36)Ar is 360-765. The R/R(a) ratio of chert increases with (40)Ar/(36)Ar from the west to the east accordingly. They have evolved from the crust source area to the mantle source area in a direct proportion. Surplus argon (40)Ar(E) in chert is in direct proportion to the R/R(a). ratio, indicating that it has the same origin of excess argon as in fluid and mantle source helium. Comparison of the R/R(a) ratios between the west and the east shows that the chert in the eastern part formed from the activity system of the bottom hydrothermal venting driven by the mantle source, where the material and energy of crust and mantle had a strong interaction in exchange; whereas in the western part, chert deposited from the floating of hydrothermal plume undersea bottom, which is far away from the Centre of activities of the hydrothermal fluid of ocean bottom. In addition, from noble gas isotope composition of chert, it is suggested that the ocean anoxia incident happened at the black shale of the Cambrian bottom probably because of the large-scaled ocean volcanoes and the following hydrothermal activities.
