江西新庄铜铅锌矿床地质特征及中深部找矿方向分析

新庄铜铅锌矿床位于白垩纪红色盆地的北部边缘与石炭、二叠系灰岩的结合处。矿区基本构造格架为一向南西倾伏的倒转背斜,并且在成岩前受到F1、F2、F3等断层横向切割破坏。对矿床地质特征、地球物理、地球化学特征等方面的研究,燕山中期岩浆活动产物具有同源同期多次侵入的村前岩体,为矿床的形成提供了大量热源及物质,区内的褶皱断裂构造为成矿提供了良好的构造条件,石炭系上统黄龙组—船山组为成矿提供了大量的物质来源。通过对前期勘查情况的研究,提出本矿区中深部找矿方向及建议。

Geological features of Cu-Pb-Zn deposit and its deep ore prospecting in Xinzhuang of Jiangxi

Xinzhuang Cu-Pb-Zn deposit was located at the junction of the northern edge of the Cretaceous red basin and Carboniferous limestone. The basic structural framework of the mining area was an overturned anticline dipping southwest, which was transversely cut by F1, F2, F3 faults diagenetie before digenesis. Studies on geological and geophysical and geochemical features of the deposit revealed that magmatism caused by Yanshanian tectonic movement offered the heat source and materials. The fractures provided channels and the Huanglong Formation and Chuanshan Formation in upper Carboniferous series provided ore forming materials. Through study, the au- thors advanced some proposals on deep ore prospecting direction in the mining area.
