| 摘 要： | 弄屯铅锌矿床位于广西西大明山钨-铋-铅-锌-银多金属矿集区北西部。矿床产于寒武系与泥盆系角度不整合面附近地层层间构造破碎带内,为中低温热液充填型矿床。初步发现5条铅锌矿带,圈定144个矿体。矿体走向主要为 NE—SW 向,倾向 SE,倾角相对较陡。矿体形态多呈脉状、似层状或透镜状。厚度、品位变化较稳定,主要为硫化铅锌矿石类型,具有矿石利用性能好等特点。控矿构造主要有NE 向及近 EW 向断裂。其矿床规模较大,具有较好的找矿前景。

Metallogenic characteristics and prospecting potential of Nongtun Pb-Zn deposit in Xidamingshan of Guangxi |

| Abstract: | Nongtun Pb-Zn deposit is located in the northwestern part of Xidamingshan W-Bi-Pb-Zn-Ag poly-metallic ore concentrated area of Guangxi.It is a low-medium temperature hydrothermal filling type deposit which occurs inside the interformational structural fracture zone around the angular unconformity plane of Cambrian and Devonian system.Preliminarily 5 Pb-Zn ore belts are discovered and 144 orebodies are blocked out.The strike of orebodies is along NE-SW trending and it dips southeast with a steep dip angle.The ore-bodies occur as veined,stratoid and lenticular in form.The variation of depth and grade of the orebodies re-mains stable,and the orebodies are mainly lead and zinc sulfide ore type which is characterized by easily ex-ploitation and good performance.The ore-controlling structures mainly include NE-trending and nearly EW-trending fractures.The scale of the deposit is large and it has favorable prospecting potential. |
