摘要
云南个旧锡矿阿西寨矿区矽卡岩型硫化矿为地下隐伏的铜、锡矿床,其矿体呈似层状、透镜状沿燕山期隐伏花岗岩体与三叠系中统个旧组(T_2g)之接触带分布。属花岗岩接触带的矽卡岩型硫化矿床;花岗岩体的侵入形成大量的矽卡岩,同时为区内多金属矿床的形成提供了热源及矿物质来源。岩体围岩蚀变矽卡岩化、云英岩化、硫化物化是主要的找矿标志。
It is an underground buried Cu-Sn deposit.The orebody is stratoid,lenticular in the contact between Yanshanian Buried granite body and Middle Triassic Gejiu Formation(T_2g),belonging to the skarn sulfide deposit in granite contact.The granite intrusion forms a lot of skarn and provide the heat and material sources for the multimetallic deposit in this area.The main prospecting criteria are the wall rock alteration skarnization,greisenization and sulfidization.
