赫章福来厂铅锌矿成矿地质特征与找矿前景分析
|
摘要
福来厂铅锌矿位于黔北台隆之六盘水断陷的威宁北西向构造变形区,产于江子山背斜NE翼,主要沿NW向构造产出,该矿为黔西北地区铅锌矿集区主要矿床之一。矿区地层具凹陷区性质,发育较全,主要为石炭系至二叠系地层,区内石炭系地层发育齐全,从石炭系下统旧司组(C_1j)至石炭系上统马平组(C_2m),主要为海相碳酸盐岩及陆源硅质碎屑岩组合,赋矿地层主要为石炭系黄龙组,岩性为白云岩、白云质灰岩。近矿围岩蚀变有铁锰碳酸盐化、褐铁矿化、白云石化、黄铁矿化及重晶石化等,其与铅锌矿关系十分密切。通过对该矿床系统取样分析、岩矿鉴定、瞬变电磁(TEM)测量及与国内外相似矿床类比分析后认为:该铅锌矿床属成矿温度相对较高～构造控矿明显的密西西比河谷型铅锌矿床,矿体的形成受断层及次生构造(节理、裂隙)的控制,毛姑坪子—福来厂矿体为矿床主矿体,确定为找矿首选区,现有氧化矿体深部具有原生矿体的找矿前景。
The Fulaichang Pb-Zn deposit is at the Liupanshui fault of the Qianbei uplift platform along with Wenning NW tectonic deformation zone.The features of the strata in the mining area are characteristics of the depositional sequence in depression area;the main distribution is Carboniferous and Permian series.The Carboniferous strata are composed chronologically from Jiusi formation(C1j) to Maiping formation(C2m) with lithology of marine carbonate rock and continental siliceous clastic rock.The ore is mostly hosted in Huanglong group with lithology of dolomite and dolomitic limestone.The Pb-Zn mineralization is intimately with wall-rock alteration included iron and manganese carbonation,limonitization,dolomitization,pyritization, baritization et al.According the results of chemical analysis,rock-mineral identification and transient electromagnetic(TEM) sounding data,and comparing with similar Pb-Zn deposits around the world,it is concluded that the Fulaichang Pb-Zn deposit with higher mineralization temperature belongs to Mississippi Valley Type and its ore bodies controlled by faults and secondary structures i.e.joints and fractures.The principal ore in the deposit is the Maogupingzi-Fulaichang ore bodies which were selected as the prior ore-exploration area. Furthermore,there is a good prospecting and potential massive Pb-Zn sulfide deposits in lower level under the oxidized ore bodies.
