东北地区中新生代盆地及其动力学——地幔柱及其调整作用:盆地形成的原动力

Dynamic of Cenozoic-Mesozoic Basin Formation on Northest China——The mantle plume and its adjustment is the primary driving force causing for basin formation

盆地的形成主要受地球演化的动力学机制的控制。由于地幔的抬升和调整是盆地形成的主要原因，地幔梯度带的倾向变化，决定了一些盆地的形态特点，即：引起盖层构造变化的原因，归结为深部构造的不同。在此基础上，将东北地区中新生代盆地划分为两类：第一类为由于地幔抬升机制控制的盆地；第二类为分布于古陆边部受地幔调整机制控制的盆地。除此之外，还有一类盆地，即受地体构造控制的盆地。并对其盖层构造的特点进行了讨论。

The evolution of the earth dynamic mechanism controlled the make of a basin on the upper crust, which due to the mantle uplift and adjustment. Some basin styles are decided by the dip changes of mantle gradient zone. Further more, the variety of the deep structures cause the changes of overlying shallow structures. Base on the natural phenomena, at Northeast China, we divide the Cenozoic-Mesozoic basins into two types. Type A, the basins are controlled by the mechanism of the mantle uplift. Type B, the basins are controlled by the mechanism of mantle adjustment and distributed on the ancient land margin. Meanwhile, there is another type, the basins are controlled by terrane. In addition, the features of overlying structure are discussed.
