摘要
银根盆地位于我国东西部两大构造区域的交汇处，存在多种构造样式。据域区地质构造分析，该盆地自中生代以来，经历了三叠纪－侏罗纪隆起上升、白垩纪下沉及新生代隆起三个阶段，体现了应力场的交替，有利于反转构造的形成。该区的地震资料证实有正反转构造存在。
The Yingen basin lies in the transitional belt between east and west tectonic areas in China,so there exist various structural styles in the basin. Analysed from regional tectonics,the basin underwent uplift during Triassic and Jurassic,subsidence in Cretaceous and uplift in Cenozoic, which caused the alternation of geological stress fields to favour the formation of inverted structure. The existence of inverted structures can be proved by seismic data in this area.
