摘要
The present paper discussed the oil-generating potential of Cenozoic coal-measure source rocks in Zengmu Basin by means of organic geochemical, organopetrological and sedimentological investigations on typical source rock samples. Integrated with the examination of depositional facies, compositional and genetic analyses of macerals indicated that Lower Miocene coal-measure source rocks with exceptional generative potential in Zengmu Basin were deposited in a mangrove depositional environment of a low-delta plain. And quantitative analyses of maceral assemblages, conventional hydrocarbon-generating parameters and investigations on the thermal evolution of source rocks showed that this suite of source rocks was of exceptional potential in generating and expulsing hydrocarbons at the low-mature stage.
