摘要
兰坪-思茅盆地"中轴断裂"为一长期活动的构造-岩浆－热活动带，盆地中部的金矿多沿该断裂带及其两侧分布，金矿的主要类型为地下热(卤)水溶滤型及次火山(斑岩)热液型。对该带南部的金矿，过去鲜见报导。从成矿条件及所获资料分析，笔者认为这是一个值得注意的金成矿区。
The Lanping－ Simao Depression middle axis fault is a tectonic－ magmatic－ thermal active belt． There are ground hot brine leached type gold deposits and subvolcanic (porphyry)hydrothermal type gold deposits distributed along both sides of this fault.There were few reports about the south part of this gold belt． Based on the mineralization conditions and the data we have obtained,the author thinks this is a gold region we must pay attention to.
