【摘要】 对金满铜矿床的宏观及微观(微量元素、同位素等)研究表明:含矿层(花开左组)中成矿元素含量很高,构成了重要的矿源层;硫来自含矿层,有机炭在成矿中起了重要的作用;成矿流体中的水应属地层水和大气降水;矿石铅同位素组成与兰坪盆地红层铅同位素组成极相似,均属壳源铅.因此认为,成矿物质应来源于地层,矿床的形成是含矿热卤水作用的结果.更多还原

【Abstract】 The macroscopic and microscopic studies（trace elements,isotopes,etc）on Jinman copper deposit show that content of the ore-forming elements in ore-bearing bed（Huakaizuo Group） is puite high.Huakiazuo Group（J₂h）is an important source-bed.The sulphur also derived from ore-bearing bed and organic carbon plays an important role in the metallogenesis.The water in ore-forming fuild is probably stratum water and meteoric water.Lead isotopic composition of the ores is quite similar to that of the red-bed of Mesozoic-Cenozoic Era in Lanping basin,all of which are of crust-source type.These effectively support the vicw that ore -forming materials derived from the source bed and the deposit was mineralized by ore-bearing hot brine.更多还原
