摘要
大岩窝铅锌矿位于扬子准地台上扬子褶皱带中。通过收集、整理前人资料以及矿区采集的典型矿石样品,从矿石类型、组构特征、矿石化学成分、矿石矿物矿相学特征及矿物微量元素特征等方面对矿石特征进行了系统的研究,为探讨矿床成因提供了一定的理论依据。研究发现,矿石的组构,矿石化学成分、矿物组合、围岩蚀变及矿石中闪锌矿的化学成分等特征均在一定程度上反映出大岩窝铅锌矿为沉积-改造层控矿床。
Dayanwo Pb-Zn deposit is located in the Yangtze paraplatform and Upper Yangtze fold belt. Author gathered predecessor＇s data and collected the typical ore samples in the mining area and systematically research its characteristics from some aspects-the ore type, fabric characteristics, chemical composition, mineral ore mineral mineralography characteristics and mineral trace elements characteristics of ore, which provides some theoretical basis for ore genesis in a certain extent. Study found that the ore fabric, ore chemical composition,mineral composition, wall rock alteration and the chemical composition of sphalerite in the ore characteristics to some extent reflects the Dayanwo Pb-Zn deposit is sedimentary-reformed stratabound ones.
