1区域地质背景巴基斯坦位于印度板块和欧亚板块之间的中特提斯造山带上,该构造带是欧亚大陆南部一条全球性纬向展布的重要构造带,其形成与演化对全球构造有着重要的影响(罗建宁,1995)(叶和飞,1999)(鲁银涛,2011)。冈瓦纳古陆裂解漂移始于侏罗纪,此后从冈瓦纳古陆分裂出来的印度板块,不断地向北移动,在白垩纪末(65 Ma) 1 REGIONAL GEOLOGICAL BACKGROUND Pakistan is located on the middle Tethyan orogen between the Indian Plate and the Eurasian Plate, a major structural belt of a global zonal distribution in the southern Eurasian continent. Its formation and evolution have the following implications for the global structure Has an important impact (Luo Jianning, 1995) (Ye and Fei, 1999) (Lu Yintao, 2011). The evolution of the Gondwanaland dissolution began in the Jurassic. Since then, the Indian plate that broke up from the Gondwanaland continued to move northward. At the end of the Cretaceous (65 Ma)
