摘要
In 5 provinces(Hainan,Guangdong,Yunnan,Guizhou and Guangxi) in South China,about 63 medium-small continental basins generated from the Late Cretaceous to Cenozoic.In the east and center of the study area,source rocks generated early(usually during Paleogene) and were featured by big thickness(400～1 000,100～900 m) and lacustrine mudstones.In the composite and superimposed basins in the west of the study area,source rocks generated late(mainly during Neogene) and were featured by smaller thickness(125～700 m) and carbonate mudstones and coal beds.According to exploration data,petroleum pools in the study area were classified into 4 types including tectonic(mainly in the eastern basins),lithologic(mainly in the western basins),stratigraphic and composite(mainly in the central basins).
