摘要
The Northeast China is held by the Siberian Plate, the North China Plate and the Pacific Plate. Since ancient continental break-up during Proterozoic this area was exposed to Xingkai, Caledonian, Hercynian, Indosinian, Yanshanian and Himalyanian orogenic activities with accretive and mosaic terrains formed. Oil-bearing basin in the area is genetically related to the “surface-crust-lithosphere three-layered stereo bridge” structural pattern and also to Pacific subduction and asthenospheric mushroom uplift shown by S seismic wave. Due to the complex deep processes of plate collision, compression, underplating, delamination, resorption, thinning, subsidence of crust the composite basin was formed by overprint of Cenozoic continental rift basin on Carboniferous-Permian marine basin.
