摘要
陕西商洛黑龙口铅锌矿位于兰桥-铁炉子-三要大断裂两侧,工作区已发现金矿体2个,铅锌矿体5个。主要含矿地层为中元古界宽坪群;其主要金属矿物为方铅矿、闪锌矿、黄铁矿及磁黄铁矿等;围岩蚀变类型以硅化、黄铁矿化、碳酸盐化为主;主要控矿因素有变形-变质作用控矿、脆-韧性断层控矿、地层控矿;认为该区域铅锌矿为属于受区域变质作用的沉积铅锌矿床。
The Heilongkou Pb-Zn deposit in Shangluo, Shaanxi lies in both sides of the Lanqiao-Tieluzi-Sanyao major fault and consists of 5 Pb-Zn orebodies and 2 Au orebodies. Ore-bearing rocks belong to the Middle Proterozoic Kuanping Group. Main ore minerals are galena, sphalerite, pyrite and pyrrhotite. Main wall rock alterations are silicification, pyritization, carbonation. Orebodies are controlled by deformation and metamorphism, stratigraphic horizon and brittle-ductile faults. The deposit metamorphosed sedimentary one.
