湖南花垣矿区狮子山矿床位于扬子地块东南缘,江南古陆西侧的褶皱带上,是一类产于寒武系清虚洞组藻灰岩地层中的大型-超大型铅锌矿。区域发育有NE-NEE向逆冲大断裂,花垣-张家界断裂、铜仁-麻栗场断裂。它们具有多期活动特征,构成向南西方撒开,往北东方收敛的帚状(杨邵祥和劳可通,2007)。矿区以下古生界寒武系地层最为发育,矿床呈NEE向展布,矿体形态简单,主要以层状、似层状、透镜状顺层产出于下寒武统清虚洞组第三、四亚段的藻灰岩、鲕粒灰岩中,矿物成分相对简
Located in the southeast margin of the Yangtze block and on the fold belt on the west side of the South China Plain, the Lion Rock Deposit in Huayuan Mining Area in Hunan Province is a large-scale super-large lead-zinc mine occurring in the algal limestone formation of the Qingxuadong Formation in the Cambrian. There are NE-NEE trending thrust faults, Huayuan-Zhangjiajie fault and Tongren-Ma Li field faults in the region. They have multi-period activity characteristics and constitute brooms that spread south and west and converge to the north and east (Yang Shaoxiang and Laocorton 2007). The following Paleozoic Cambrian strata below the mining area are the most developed Cambrian strata, the deposit is NEE to spread, the ore body morphology is simple, mainly layered, stratified, lenticular outcropping in the Lower Cambrian Qingxuendong formation third, four Sub-algal limestone, oolite limestone, the mineral composition is relatively simple
