THE LOWER CRETACEOUS PETROLEUM SYSTEM IN NE CHINA

Dou Lirong*

NE China is situated on the pre-Mesozoic folded belt between the Siberian and Sino-Korean Cratons. Beginning in the Late Jurassic, the oceanic Izanagi Plate was subducted NWwards beneath the Eurasian Plate, resulting in a change in the structural setting from north-south compression to NW-SE extension leading to intracontinental rifting. The Early Cretaceous marked a peak in the development of syn-rift lacustrine basins, and there are about 200 rift depressions in the study area. Left-lateral strike-slip activity on the NE-SW oriented Tan-Lu Fault, and a change in the rate and direction of subduction of the Izanagi Plate, ended the syn-rift stage. Thick, post-rift lacustrine sequences only developed in the Songliao Basin, and today form source and reservoir rocks at the "giant" Daqing oilfeld.
