摘要

 In this research, new molybdenum isotopic compositions of the bitumen,in the Gaungyuan section, Sichuan Province, as well as trace elements are determined. The results show that it has a large variation of δ⁹⁸Mo(+0.34‰~+1.71‰) in this region, reaching the range of anoxic sediments δ⁹⁸Mo in general. The characteristics might be related to local intense hydrothermal erupting, corresponding to the large quantity of H₂S and HS-into the contemporaneous seawater.
