| 摘 要： | 片麻岩穹窿是研究俯冲-折返和碰撞-折返造山过程的重要窗口。已查明的大量青藏高原片麻岩穹窿(群)分布在古特提斯和新特提斯大洋俯冲-折返以及地体碰撞-折返过程中。松潘-甘孜造山带中雅江甲基卡片(麻)岩穹窿的三叠纪变质片岩的含矿伟晶岩脉中发现了超大型锂矿床,揭示片(麻)岩穹窿构造与同构造花岗岩、含矿伟晶岩脉以及大型印支滑脱带在时空和成因上有天然联系,为片麻岩穹窿的找矿前景提供了范例。

| Abstract: | The gneiss dome is an important tool to reveal the orogeny processes of subduction-exhumation and collision-exhumation. In the Tibetan Plateau, many gneiss dome swarms are distributed in the Paleotethyan and Neotethyan terranes, formed during the subduction-exhumation and/or collision-exhumation process. Superlarge spodumene deposit has been discovered in the pegmatite veins intruded the schist of the Triassic Jiajika gneiss dome in the Songpan-Ganze orogen, showing close spatio-temporal linkage between gneiss domal structure, syn-tectonic granite, ore-bearing pegmatite, and indosinian large decollement zone. The prospecting and exploration of relevant deposits in gneiss domes are a target in the future. |
