西藏东部到云南西北,形成了著名的三江-特提斯成矿带,有着丰富的铜、铬、钴、铅、锌及金、铂族元素和稀土元素储量(邓军等,2010)。三江成矿带内成矿类型丰富多样,如斑岩型铜钼矿床、喷流沉积型铁矿、剪切型金矿等(Hou et al.,2007)。印度板块与欧亚大陆板块碰撞后在青藏高原东缘形成金沙江-哀牢山-红河走滑剪切带,沿此构造带分布着众多喜马拉雅期富碱斑岩侵入体,与许多具有前景的斑岩型铜、钼、金矿床存在密切联系(侯增谦等,2004;Hou et al.,2006;Liang et al.,2007)。
The eastern part of Tibet to the northwest of Yunnan formed the famous Sanjiang-Tethys metallogenic belt with abundant copper, chromium, cobalt, lead, zinc and gold, platinum group elements and rare earth elements (Deng et al., 2010). The metallogenic types in the Sanjiang metallogenic belt are rich and varied, such as porphyry copper-molybdenum deposit, jet-deposited iron ore, shear-type gold ore, etc. (Hou et al., 2007). After the Indian plate collided with the Eurasian plate, the Jinshajiang-Ailao-Honghe strike-slip shear zone was formed on the eastern edge of the Qinghai-Tibet Plateau. Along this structural belt, there are many Himalayan alkali-rich porphyry intrusions with many promising Porphyry copper, molybdenum and gold deposits are closely related (Hou Zengqian et al., 2004; Hou et al., 2006; Liang et al., 2007).
