摘　　要：红花坪铅锌矿位于南秦岭旬阳盆地金铜、铅锌、汞锑等多金属成矿带内,为一沉积-改造型铅锌矿床。矿区出露地层主要为古生界泥盆系和志留系一套浅变质的细碎屑岩和碳酸盐岩沉积建造,褶皱、断裂发育,热液活动强烈,为成矿物质的活化、运移创造了良好的条件。矿体赋存于下志留世梅子垭组绢云千枚岩及下部石英脉中,受一定的地层岩性、古地理环境和构造控制。目前Ⅰ-1铅锌矿体控制长度已超过1 km,矿体连续性好,形态单一,矿物成分简单,锌含量高,有望成为一中型规模的铅锌矿床。Honghuaping lead-zinc deposit is located in the polymetallic metallogenic belt of Au,Cu,Pb-Zn and Hg-Sb in Xunyang basin of southern Qinling mountain.It is a sedimentary-reformed lead-zinc deposit.Exposed strata in mine area are mainly Paleozoic Devonian and Silurian metamorphic shallow clastic and carbonate sedimentary rocks.Folds and faults developed well in this area.Hydrothermal activities are strong,which will create good conditions for activation and migration of mineralization materials.Ore bodies occurred in Meiziya sericite phyllite and quartz veins in the lower Silurian,and controlled by a certain lithology,ancient geography and strucutures.Currently,the controlling length of No.Ⅰ-1 lead and zinc ore body is more than 1km with good continuity and single form.The components of minerals are simple with high zinc content.It is expected to become a medium-sized lead-zinc deposit.
