东北地区不是海西期褶皱变质带(或造山带),而是早石炭世以来拼合成统一的复合地块,我们称为"佳木斯-兴蒙地块".东北地区上古生界不是中 -新生代盆地的结晶基底,而是具有准盖层性质的陆相 -海相沉积盖层.晚古生代海相沉积建造中,暗色泥岩和碳酸盐岩发育,具有潜在的生烃潜力,是东北地区油气资源勘查的重要新层系.提出以嘉荫-牡丹江断裂和嫩江 -开鲁断裂为界,将东北地区中-新生代盆地划分为西部、中部和东部三大盆地群,并确定了各盆地的成因类型、石油地质特征及时空演化规律.

The Northeast China is not a Hercynian folded metamorphic belt (or orogenic belt),but a compound terrain pieced together after the Early Carboniferous.We name it "Jiamusi-Xingmeng Terrain".The Upper Paleozoic is not the crystalline basement for Meso-Cenozoic basins in Northeast China,but marine and continental sedimentary cover of para-caprock nature.The Late-Paleozoic marine sequences have well-developed dark mudstones and carbonates,which is the evidence for hydrocarbon potential.These sequences are important new targets for exploring oil and gas in Northeast China.We propose that the Meso-Cenozoic basins in Northeast China could be divided into three basin groups-the west,the middle and the east separated by the Jiayin-Mudanjiang fault and the Nenjiang-Kailu fault.The genetic type,characteristics of petroleum geology and the temporal and spatial evolution pattern of each basin are also discussed in this paper.
