摘要/Abstract

摘要：

以产于黄岗—甘珠尔庙成矿带的铅锌矿产为预测矿种,以铅锌矿矿床为目标物,较系统地分析了地层、岩浆岩等地质条件与铅锌矿产的关系,查明各种地质条件对铅锌矿产的控制作用与控制方式。二叠系与铅锌成矿在空间分布和物质成分方面有着密切的联系,锰质钙铁辉石夕卡岩及火山沉积岩为铅锌成矿提供物质来源;燕山期岩浆侵入活动形成的中酸性侵入体为有利岩体;成矿带内多组方向断裂的交汇部位是矿化富集区,使得矿床以北东成带、东西成行,各矿床之间具有等距离的特点进行分布。由地质信息、地球化学信息及矿化信息构成的矿床级别的综合信息找矿模型,为成矿带内铅锌矿产预测提供了理论依据。

Abstract:

Taking the leadzinc deposit of HuanggangGanzhuermiao Metallogenic Belt as a predicted mine, this paper systematically analyzed the relationships between geological conditions including strata and magmatic rocks, etc. and leadzinc deposits, and found out the control action and manner of geological conditions on leadzinc deposit. The leadzinc mineralization has a close relationship with the Permian in spatial distribution and content compositions. Manganese calcium pyroxene skarn and volcanic sedimentary rocks provide material for leadzinc deposit. The beneficial rocks are Yanshanian acid intrusive bodies. In the metallogenic belt, the concentrated mineralization area is the intersection of multiple parts of fractures. The differently striking faults make deposits form a NE zone and an EW row, and the deposits distribute with equal intervals. Finally, we established a comprehensive prospecting model for leadzinc deposit, which consists of geological, geochemical and mineralization information and provides the theoretical basis for predicting the leadzinc deposit within the metallogenic belt.
