兰坪盆地位于澜沧江断裂带与哀牢山推覆体之间 ,内有丰富的金属矿床与盐类矿床 ,大部分是新生代形成的 ,且大多为低温热液矿床。裂变径迹法对兰坪盆地构造热演化与成矿作用的研究结果表明 :盆地自中生代以来 ,至少经历了三次构造热事件 ,出现了三次成矿作用过程 ,成矿作用是由盆地西缘向中央地带逐渐发展的
The Lanping basin is located between the Lancangjiang fault zone and the Ailao Mountain nappe. There are abundant metal deposits and salt deposits in the Lanping basin, most of which were formed in the Cenozoic, mostly of low-temperature hydrothermal deposits. The results of fission track method for tectonic thermal evolution and metallogenesis in Lanping basin show that the basin experienced at least three tectono-thermal events since the Mesozoic, and three metallogenic processes have occurred. The metallogenetic effects are caused by the west margin of the basin The central area is gradually developing
