摘要
个旧锡矿区是个老矿区 ,开采历史悠久 ,目前资源紧张 ,急需开展找矿增储研究。 33号矿群是近年新勘查的矿体 ,以接触交代矿床为主 ,经工程揭露 ,现已探明一定锡储量 ,目前矿山生产急需向外围找矿 ,以期扩大储量 ,但苦于找矿工程方向不清。我们通过对隐伏花岗岩体形态 ,锡、铜的矿化强度模型 ,地表地球化学结合地质研究 ,指出 33号矿群的北东 ,芦塘坝断裂与炸药库断裂交截部位附近为最有利的找矿空间。
Gejiu tin district is an old mine with a long exploitation history, but tin resources are hard up at present. No.33 orebody group is a newly prospected one which consists mainly of magmatic hydrothermal mineralization. According to the producing scale, it is essential to seek for more resources in the surrounding district. Research on the rock geochemistry and concealed granite mass shape, and establishing the models of Sn and Cu mineralizing intension indicate the following districts are the most favorable for seeking for concealed orebodize: the district north east to No.33 orebody group, the connecting position and nearby area of the Lutangba fault cut by the Zhayaoku fault.
