| 摘 要： | 扎西康铅锌锑多金属矿已发现规模较大的四个矿体,控制资源量达100万吨以上.矿体均分布在NNW或NNE张扭性断裂破碎带内,受断裂破碎带控制,矿体与围岩界线明显.铅同位素位组成显示成矿物质主要来源于上地壳,包裹体研究成矿流体为中低温-低盐度成矿,氢、氧、硅同位素组成显示成矿流体主要为大气降水下渗循环构成的地热水.硫同位素特...

| Abstract: | There are four large scale existing ore-bodies in the Zhaxikang Pb-Zn-Sb polymetallic deposit.The controlled metal reserves are more than one million tones.The ore-bodies are located in NNW or NNE trending extension-shear fault and fracture belts.The border between the ore-body and wall rock is clear.Lead isotopic composition indicates that ore material is mainly from the upper crust.Inclusion research result shows that mineral fluid is of middle temperature with middle and low salt degree.Hydrogen,oxygen a... |
