青藏高原的隆升机制,用现今印度板块单向向北俯冲的模式或类似模式已经难以解释。因在青藏高原的北部也已发现有与高原南缘喜马拉雅地区相似的、与俯冲碰撞作用有关的新生代火山岩和花岗岩带。国内外现都有研究者提出三向俯冲的模式.青藏高原的隆升与高原周边盆地从三个方向的俯冲相联系(即印—恒盆地由南向北的俯冲,塔里木盆地由北向南的俯冲,卡拉库姆盆地由北西向南东的俯冲。也有学者提出印度板块向北俯 The uplift mechanism of the Qinghai-Tibet Plateau has been difficult to explain with the one-way subduction of the Indian plate nowadays or the like. Because of the discovery in the northern part of the Qinghai-Tibet Plateau and the Himalayan area on the southern edge of the plateau similar to the subduction collision of Cenozoic volcanic rocks and granite belt. Researchers at home and abroad have proposed a three-way subduction model.The uplift of the Qinghai-Tibet Plateau is related to the subduction of the basins around the plateau in three directions (ie, the subduction of the Indosinian basin from south to north, the north-south of the Tarim Basin Subduction, the Karakum basin from Northwest to South East subduction. Some scholars have proposed that the Indian plate to the north
