三江成矿带是全国重点成矿区带之一,兰坪-思茅盆是其中一个重要组成部分,盆地西界为澜沧江断裂,东界为金沙江-哀牢山断裂,盆地中央发育有近南北-北北西向隆起带,称为“中轴断裂带”(管烨等,2006)。沿中轴断裂带两侧发育有大量铜铅锌银矿床、铅锌银矿床以及钾盐矿床,其中最为著名的为金顶超大型铅锌矿床与勐野井大型钾盐矿床(尹汉辉等,1990)。
Sanjiang metallogenic belt is one of the key metallogenic belts in the country. Lanping-Simao basin is one of the important components. The western boundary of the basin is the Lancangjiang fault, the east boundary is the Jinshajiang-Ailao-Shan fault, and the Central South China- North-west-uplift belt, known as the “shaft fault zone” (Guan Ye et al., 2006). A large number of Cu, Pb, Zn and Ag deposits, Pb-Zn-Ag deposits and potash deposits are developed along both sides of the central axis fault zone. The most famous ones are the Jinding ultra-large lead-zinc deposits and the Meng Yejing large-sized potash deposits (Yin Hanhui et al., 1990) .
