The Zhundong coalfield is a very large coal deposit, currently under exploration, and promises to be an important coal mining resource in Western China. The coal reserves amount to 164 Gt. At Xiheishan and Wucaiwan, the coal-bearing units are the Badaowan (Lower Jurassic) and, especially, the Xishan
of hopanes and higher carbon preference index (CPI) values (in-C22 to n-C3o) show significant bacterial contributions in samples characterized by high values of tissue preservation index (TPI). The C31 a~ (22S/ 22S+22R) hopane and C29 aaa (20S/20S+20R) sterane ratios show least variation through the
