冈底斯成矿带位于班公湖-怒江缝合带与雅鲁藏布江缝合带之间,为一条近东西向,长可达2000km的巨型成矿带。在青藏高原形成的过程中,造山作用引起的地壳超常的增厚、融离、翻涌,壳/幔物质携带着大量的成矿流体在碰撞造山动力作用下沿岩浆通道上涌,到达上部地壳有
The Gangdese metallogenic belt is located between the Bangong-Nujiang suture zone and the Yarlung Zangbo suture zone and is a giant metallogenic belt nearly up to 2000 km in length that runs east-west. In the process of the formation of the Qinghai-Tibet Plateau, the crustal anomalous thickening, fissuring and overturning caused by orogeny, the crust / mantle material carrying a large amount of ore-forming fluid upwelling along the magma channel under the action of collision orogeny and reaching the upper crust
