摘要
云南已发现的独立铂族金属矿床成因类型均属单一的岩浆型矿床,分为铜镍硫化物型和钛磁铁矿型,以铜镍硫化物型矿床为主,占云南铂族金属矿床总数的90%。铂族金属矿床成因与镁铁-超镁铁杂岩体有关,空间上主要分布在大理-弥渡-金平、元谋-牟定一带,其他区域零星分布。形成时代主要为晚二叠世。在此基础上,本文进一步提出大理-金平,永仁-牟定2个铂族金属矿床的主要找矿远景区。
The discovered independent deposits of Pt family metal are all belonging to the single magmatic deposit in genesis type,which can be divided into the Cu-Ni sulfide type and Ti magnetite type and the former is the main one.,accounting for 90%of the Pt family metal deposit in Yunnan.The Pt family metal deposit is related with MgFe-ultra MgFe complex body in genesis,mainly distributed in Dali,Midu,Jinping,Yuanmou,Yongren,Mouding area and scattered in some other areas.The formation period is mainly in Late P.In this Paper,we put forward Dali-Jinping,Yongren-Mouding 2 main prospective prospecting areas.
