Immature crude oils in the salt lake depositional environment are related to organic matter precipitated at stage of carbonate in salt lake sedimentation sequences
Pa. Peng et al., Immature crude oils in the salt lake depositional environment are related to organic matter precipitated at stage of carbonate in salt lake sedimentation sequences, CHIN SCI B, 45, 2000, pp. 1-6
The present paper studies the mineralogy and geochemistry of a geological s
ection in Jianghan basin. Widely distributed immature oils in this basin ha
ve been shown to relate to the carbonate depositional stage of salt lake se
dimentation cycle. It is concluded that only when the content of organic ca
rbon in the rocks is taken into account, is it meaningful to calculate the
immature oil in the source rocks.
