摘　　要：Many studies have focused on the Cretaceous evolution of NE China,including the 973 Scientific Exploration Well Work program,which completed two drill holes in this area.The Cretaceous Basin Group of eastern NE China is highly altered,so the evolution,controlling factors and interpretation of the Early Cretaceous Dasanjiang Basin are controversial,and fundamental aspects of the rocks are poorly understood.The Boli Basin is the largest Cretaceous basin within NE China,but the temporal and spatial extent of Mesozoic strata within this basin,especially the Dongshan Formation,arc not well-known.
