广西恭城县鸡笼山铅锌矿区位于老厂穹隆中部,出露地层有寒武系边溪组二段(∈b2)、三段(∈b3)、四段(∈b4),泥盆系下统莲花山组下段(D1l1)。矿体主要产出于寒武系边溪组(∈b)层位中,受北东向断裂构造控制,沿断裂破碎带充填,呈似层状、不规则脉状产出,倾向南东及北西,倾角一般60~80°;全矿区共发现6条矿体。矿床属中温热液断裂充填型脉状矿床。其找矿标志有:北东—北北东向的张扭性断裂带、地表风化带有铁染或褐铁化显示、轻变质的角砾岩带、受成矿标高控制、含矿地段硅化、白云石化、黄铁矿化、绢云母化等多种热液蚀变叠加的地段是找矿有利的地段。
The Jigangshan Pb-Zn deposit in Gongcheng County of Guangxi Province is located in the middle of the dome of the old plant. The exposed strata are the second member of the Cambrian Paixi Formation (∈ b2), the third member (∈ b3), the fourth member (∈ b4) Lower Lianhuashan Formation lower (D1l1). The main orebody occurred in the Cambrian Xiangxi Formation (∈b) layer, controlled by the NE-trending fault structure and filled along the fault zone. The ore bodies appeared layered and irregularly veined, Northwest, dip generally 60 ~ 80 °; total mining area found a total of 6 ore bodies. The deposit belongs to medium temperature hydrothermal fracture filling type vein deposit. The ore prospecting markers include: North-East-North-East-East shear-torsional zone, surface weathered with iron-dyed or brown-ironed, light metamorphic breccia zone controlled by mineralization elevation and silicified ore-bearing area , Dolomitization, pyrite, sericite and other hydrothermal alteration overlay of the lot is looking for a favorable location.
