| 摘 要： | 位于班公湖—怒江和雅鲁藏布江两条巨型板块结合带之间的冈底斯构造带,是一个经历了晚古生代—中生代复杂构造演化的碰撞造山带。复杂的构造演化控制着该区的岩浆岩演化,花岗岩极为发育,成因类型复杂。与铀成矿作用密切相关的"S"型花岗岩的分布受构造演化阶段的控制,主要为燕山晚期—喜山期构造—岩浆的产物,此类花岗岩较其它成因类型花岗岩铀含量高,具有较好的形成花岗岩型铀矿的成矿条件。

| Abstract: | The Gangdis6 tectonic belt located between the Bangong Co-Nujiang and Yarlung Zangbo plate junction is a collision orogenic belt that underwent complicated tectonomagmatic evolution from Late Paleozoic Era to Mesozoic Era with ocean-continent during D--T2, basin-mountain during T3--K and crust-mantle during E--Q. The S-type granite correlated closely with uranium mineralization is controlled by tectonic and was emplaced during Late Yanshanian-Himalayan epoch. The granite is characterized by enrichment in uranium. |
