河南水洞岭铜锌矿床特征、成因及找矿潜力分析

Characteristics,genesis and prospecting potential analysis of the Shuidongling Cu-Zn deposit in Henan

水洞岭铜锌矿床矿体赋存在石英角斑凝灰岩中,呈似层状、透镜状产出,与地层产状一致,矿石具块状、浸染和条带状构造,中细粒结构,主要矿石矿物为黄铁矿、黄铜矿、闪锌矿和方铅矿等。地质和地球化学证据表明,水洞岭铜锌矿床为海相火山沉积块状硫化物矿床。通过找矿潜力分析在矿区及外围圈出了四个找矿靶区:黄土岭、老胡家、张圪塔和砂固堆。

The orebodies of the Shuidongling Cu-Zn deposit occurred in quartz keratophyrie tuff with their occurrence being stratiform-like state and lens, which is accordance with the strata occurrence. The ores have massive, disseminating and banding structure, and middle-fine granularity texture, as well as major ore minerals of pyrite, chalcopyrite, sphalerite and galena etc. The geological and geochemical evidences prove that the Shuidongling Cu-Zn deposit is a marine volcanical sedimentary massive sulphide deposit. Four prospecting targets,that are Huangtuling, Laohujia, Zhanggeda and Shagudui, have been delimitated in ore area and its periphery through analyzing prospecting potential.
