印度与亚洲大陆碰撞构造模式图
在50Ma之前，新特提斯洋向Kohistan岛弧(KIA)和冈底斯大陆弧之下俯冲；在~50Ma，印度大陆东段与亚洲大陆(冈底斯弧)碰撞，而在西段与Kohistan岛弧碰撞，并深俯冲形成超高压变质岩；在~40Ma，印度大陆+岛弧与Karakoram大陆弧在西段发生碰撞，超高压变质岩折返；在~30Ma印度大陆俯冲到亚洲大陆之下
Tectonic model of the India and Asia collision
Before 50Ma, the Tethyan oceanic plate subducted beneath the Kohistan inland arc (KIA) and Gangdese continental arc; At ca. 50Ma, the eastern segment of Indian continent collided with the Asian continent (Gangdese arc), and the western segment of Indian continent collided with the Kohistan inland arc, and subducted into the mantle depth, resulting in the formation of UHP rocks; At ca. 40Ma, the Indian continent+KIA collided with the Karakoram continental arc and the UHP rocks exhumed; At ca. 30Ma, the Indian continent subducted beneath the Asian continent
