| 英文摘要 | The collision between the Indian and Eurasian continents is the result of the combined interaction action between the spreading of the Indian plate and the closure of the Tethys. Either the oceanic subduction of the Tethys or the subsequent continental subduction of the Indian landmass were all directed to the north beneath the Eurasian continent, as shown by the occurrence of the widespread magmatite along the Gangdese belt and the creation of the Tibetan Plateau. However, in fact, there don't exist any north-dipping structures on the surface of the Yalungzangbo suture zone, but mostly the south-dipping structures, namely the Great Counter Thrust System of the Himalaya, indicating that the Indian landmass obducted to the north with respect to the Asia continent. There exist two sets of the molasse deposits along the Yalungzangbo suture zone, namely Liuqu and Dazhuka, dated as Eocene and Early Miocene image. Based on synthetic analysis and study, this paper herein proposes that they were all the products of the northward obduction of the Indian landmass. The former was produced by the obduction of the Indian crust over the Eurasian continent, which led the occurrence of flextural bending of the southern margin of the Asian continent, resulting in the uplift of the Gangdese belt. While the latter results from the obduction of the Indian landmass over the Tethyan oceanic crust, as a result of rapid spreading (> 140mm/yr) of the Indian plate. The subduced oceanic crust of the Tethys may have still preserved beneath the northern margin of the Indian landmass, as shown by the abnormally thick crustal thickness (similar to 70km) of the Tethys Himalayan belt. The northward movement of the Indian landmass is accommodated by the strike-slip movement along the Ninety-east Range and Maldives Islands. |
