【摘要】 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更多还原

【Abstract】 Lanping Basin is situated between Lancangjiang fault and Ailaoshan nappe.Abundant metal and salt deposits emerge in the basin,most of them are epit hermal hydrothermal deposits formed in Cenozoic era.Fission track analytical res ults about tectonothermal evolution and metallogenic processes show that Lanping Basin at least undergoes three stages of tectonothermal events, accompanied by three stages of metallogenic processes which develop gradually from western edg e to the center of the basin.更多还原
