布途金子铅锌矿位于川滇黔铅锌成矿城内,矿区地层为一套碳酸盐岩沉积建造,矿体赋存予灯影纽上段地层中,受地层岩性及构造控制。Ⅰ和Ⅱ号铅锌矿体目前尚未控制最大延深,全部为氧化矿石。通过时数千米探矿坑道施工,将研究区与国内及世界典型MVT铅锌矿床对比,认为布途金子铅锌矿床属MVT铅锌矿亚类;通过与周边矿床对比,指出矿床深部极有可能存在炎稚富的原生硫化矿,有望成为0中型铅锌矿床。
佈途金子鉛鋅礦位于川滇黔鉛鋅成礦城內,礦區地層為一套碳痠鹽巖沉積建造,礦體賦存予燈影紐上段地層中,受地層巖性及構造控製。Ⅰ和Ⅱ號鉛鋅礦體目前尚未控製最大延深,全部為氧化礦石。通過時數韆米探礦坑道施工,將研究區與國內及世界典型MVT鉛鋅礦床對比,認為佈途金子鉛鋅礦床屬MVT鉛鋅礦亞類;通過與週邊礦床對比,指齣礦床深部極有可能存在炎稚富的原生硫化礦,有望成為0中型鉛鋅礦床。

Butujinzi lead-zinc ore deposit is situated in the metallogenetic area extending across Sichuan-Yunnan- Guizhou provinces. Strata in the mining area are a series of earbonatite sediment formations. The ore bodies occurred within the upper members of Dengying Formation and are controlled by both formation lithology and structure. At present, the maximum dip extension of I and II lead-zinc ore bodies have not been controlled. The ore bodies are all oxide ones. By constructing the exploratory trenches for several kilometers, concluding of the exploration and compa- ring with classic lead-zinc deposit at home and abroad, we argue that this deposit belongs to a subclass of MVT lead- zinc ore deposit. Through comparing with the surrounding deposits, the paper indicates that the large and high-grade sulphide ores probably exist in the deep of the deposit,expecting to be a medium lead-zinc ore deposit.
