依据恐龙化石恢复印度板块的运行轨迹

The recovery of the trajectory of India n plate based on dinosaurs

越来越多的事实表明,印度板块曾经连续两次撞击了欧亚板块。第一次发生在近200Ma前,通过印度板块将冈瓦纳大陆上的恐龙动物群带到了亚洲,使中国首次出现了早侏罗世恐龙。确切地说,中国恐龙起源于印度板块的第一次撞击。侏罗纪之后,印度板块又被引发起顺时针转动,在其东部出现了与泰国之间的断裂,并最终孕育着孟加拉湾的形成,为第二次撞击拉开了序幕。55Ma前印度板块再次撞向欧亚板块的西藏地区,造就了喜马拉雅山。

There exists more and more evidence that the Indian plate has collided with the Eurasian plate twice.The first collision happened two hundred million years ago,by which the Gondwana dinosaur fauna was brought into Asia through the Indian plate.It was then that the Early Jurassic dinosaurs appeared in China for the first time.It can be accurately said that the dinisaurs in China originated from the first collision of the Indian plate.After Jurassic the Indian plate was caused to make clockwise rotation and there occurred a rift in the eastern part of Thailand.The movement eventually led to the formation of Bay of Bengal,which acted as the prologue of the second collision.55 million years ago the Indian plate moved and collided for the second time with the Eurasian plate in Tibetan area,giving birth to the Himalayas.
