兰坪—思茅中、新生代盆地砂页岩中铜矿床的微量元素特征、稀土配分型式以及硫、铅、碳、氧、氢、硅等同位素组成等表明 ,成矿金属物质、硫和碳 ,既有来自赋矿岩石 (包括火山岩 ) ,又有来自基底岩石 ,同时还有深部物质的参与。成矿溶液主要来自大气降水 ,矿化和蚀变作用是在水 /岩比值较低的体系中进行的。 Trace element characteristics, REE patterns and isotopic compositions of sulfur, lead, carbon, oxygen, hydrogen, and silicon in the Lanping-Simao sandstone in shale show that metallogenic metals, sulfur and carbon , Both from the ore-bearing rocks (including volcanic rocks), but also from the basement rock, as well as deep material participation. The ore-forming solution is mainly derived from atmospheric precipitation. Mineralization and alteration are carried out in a system with low water / rock ratio.
