    印度板块-古亚洲板块碰撞及亚洲恐龙的出现

    Collision between the Indian plate and the paleoAsian plate and the appearance of Asian dinosaurs.

    • 摘要: 印度板块在5500万年前的古近纪撞击了亚洲板块,造就了东西走向的雅鲁藏布江水系和喜马拉雅山系。根据近年来的研究,笔者又提出一个新观点:印度板块在约2亿年前与亚洲板块发生碰撞时,将一个发源于非洲、南美洲的“冈瓦纳恐龙动物群”送上亚洲大陆,在中国西南地区形成以禄丰龙、蜀龙、峨眉龙、马门溪龙为特征的恐龙类动物群。这一事件不仅使亚洲首次出现了恐龙动物,而且板块相撞还造就了南亚地区南北走向的横断山脉和伊洛瓦底江、怒江、澜沧江、金沙江等纵向水系,以及四川盆地的形成。

       

      Abstract: About 55 Ma ago, the India plate collided with the Asian plate, forming the E-W-trending Yarlung Zangbo drainage system and Himalaya mountain range. According to recent studies, the authors propose the following new view: a similar collision between the above-mentioned plates had already taken place 200 Ma ago (in the Early Jurassic), which put a Gondwana dinosaurs fauna originating in Africa and South America on the Asian continent, forming a Lufengosaurus-Shunosaurus-Omeisaurus-Mamenchisaurus fauna in southwestern China. This event not only brought Asia dinosaurs but also gave rise to the S-N-trending Hengduan Mountains and such longitudinal drainage systems as the Irrawaddy River, Nujiang River, Lancang-Mekong River and Jinsha River in South Asia and the Sichuan basin in China.
