| 摘 要： | 大庙岭铅锌矿位于马海复背斜倾伏端,宛田-马堤断裂带东侧,东邻燕山晚期铅厂花岗岩小岩株。矿体受NEE-NE向的断裂构造控制,呈不规则脉状、透镜状产于下古生界寒武系边溪组和奥陶系白洞组中,为受断裂破碎带控制的低温热液铅锌矿床。赋矿岩石为灰岩、白云质灰岩、泥砂岩、粉砂岩。铅锌矿矿石构造以脉状、角砾状为主,部分为块状、浸染状,硅化、碳酸盐化和绿泥石化与铅锌矿化关系密切。结合地质、物化探资料,笔者认为I号矿体和II号矿体的含矿断裂破碎带向深部有较大延深趋势,矿区深部具有较好的找矿前景。

| Abstract: | Damiaoling Pb-Zn deposit in Lingui of Guangxi is located at the pitching end of Mahai anticlinori-um,at east of Wantian-Madi fault zone,and it is close to Yanshan Qianchang granitic bodies in the east. This ore-body is controlled by NEE-NE trending faults,and occurs in irregular vein structure and lenticular structure in Bianxi Formation of Cambrian system and Baidong Formation of Ordovician system of lower Pa-laeozoic Erathem.The deposit is a low temperature hydrothermal Pb-Zn deposit controlled by faulted frac-ture zone.The host rocks include limestone,limestone dolomite,pelitopsammite,and siltstone.The ore structures of Pb-Zn deposit are mainly in vein or brecciated forms,and part of them are in massive or dissem-inated forms.silicification,carbonatization and chloritization are closely related to mineralization of Pb-Zn ores.Based on geological,geophysical and geochemical data,the author believes that ore-bearing faulted fracture zone in No.I and No.II ore-body has a great deepening trend into the depth,and the deep level in the mining area has a favorable prospecting potential. |
