| 摘 要： | 青藏高原拉萨地块是印度板块与欧亚板块碰撞的重要地区之一,其中广泛发育的碰撞—后碰撞岩浆岩记录了新生代以来印度大陆岩石圈向北俯冲的全过程以及拉萨地块在碰撞-后碰撞之后的岩浆作用类型.基于对措勘—赛利普地区新生代火山岩地球化学及Sr、Nd同位素资料的分析,表明火山岩中以明显富碱和高钾为特征；Sr同位素呈递增而Nd同位素呈递...

| Abstract: | The Lhasa block of the Tibetan plateau is one of the main areas collided by the Indian plate and Eurasian plate.The extensively developed magmatic rocks in this area record the whole process which the Cenozoic India continental lithosphere subducted to north and the type of magmatism of Lhasa block after collision and collision-after.The geochemical analysis of the Cenozoic volcanic rocks and Sr,Nd isotopic data from the Cuoqin-Sailipu area indicate that the volcanic rocks transiste from calcium rock to alk... |
