The Yinggehai Basin, an elongate Cenozoic transtensional basin, is located in the connected area between Indochina block and northern continental margin of South China Sea. Dynamical mechanism for generation and evolution of Yinggehai Basin has become the debated focus due to its complicated tectonic setting. View on the regional tectonic evolution, we study the tectonic evolution features on Indochina block systemically, which puts significant effects on the development of Yinggehai Basin. It suggests that the escape-extrusion tectonic and compression-extension tectonic systems are the main factors controlling the tectonic evolution of Yinggehai Basin. Three tectonic evolution phases of Yinggehai basin, that are sinistral strike-slip extension Previous HitphaseNext Hit, middle-lower crust ductile extension and thermal subsidence Previous HitphaseNext Hit, and accelerated subsidence Previous HitphaseNext Hit, are divided. In thermal subsidence Previous HitphaseNext Hit and accelerated subsidence Previous HitphaseTop, a diaper-related petroleum system developed.
