The early stage of me tamorphism happened before deformation in the upper mantle at about 60-70km. Then metagabbro emplaced rapidly at about 40 km by diapirism and perhaps amalgamated with cool subducted oceanic crust. After that, rapid cooling retrograde metam orphism occurred. Early rapid ocean spreading was constrained because subduction appeared. Therefore, metagabbro continued to uplift under the slow extension. At last, it obducted and thrusted to outcrop on the surface.
变形前的早期变质可能发生在60~70km处的上地幔,然后变质辉长岩快速"底辟"构造侵位,上升至约40km深处,可能与俯冲的冷洋壳并置,发生快速降温退变反应;因俯冲作用的开始,抑制了洋盆快速扩张,变质辉长岩在减速伸展环境下继续抬升减压;后期又由于仰冲推覆,最终出露地表。

Based on the analysis on the oil sources and migration pathway of this area, the mineralization modes of the oil sand in the area are derived in this paper. Main conclusions are drawn as follows: a. multiphase tectonic activity resulted in multistage hydrocarbon generation of the source rock; b. threestage tectonic activity and threestage mineralization process formed a great deal of unconformity and fault pathway, thus the crude oil could migrate in a long distance; c. the tectonic activity in Yanshan and Himalayan stages uplifted the edge of the basin and the eroded reservoir outcropped to the surface, the light oil escaped and then the oil sand resource formed; d.
