广西西大明山地区铅锌银多金属矿床成矿分带性成因探讨

Discussion on metallogenic zoning and genesis of Pb Zn Ag polymetallic deposits in Xidamingshan area,Guangxi

笔者于西大明山地区提出一个找矿预测区:在渌美找矿靶区寻找铅锌钨铋多金属矿,该区与罗维大型层状矽卡岩型铅锌钨铋多金属矿床成矿模式十分相似,是寻找罗维式铅锌钨铋矿的有利地区,有望形成1处大中型矿产地。文章通过介绍广西西大明山地区区域成矿的分带性特征并分析了成矿分带性成因,进一步提出找矿方向,对该区今后的地质找矿工作具有一定的指导意义。

The author puts forward a prospecting prediction area in the Western Damingshan area:looking for Pb Zn w Bi polymetallic deposits in the Lumei prospecting target area.The metallogenic model of this area is very similar to that of Luowei large-scale layered skarn type Pb Zn w Bi polymetallic deposit.It is a favorable area for looking for Luowei Type PB Zn w Bi deposit and is expected to form a large and medium-sized mineral field.This paper introduces the zonal characteristics of regional mineralization in Xidamingshan area of Guangxi,analyzes the causes of zonal mineralization,and further puts forward the prospecting direction,which has a certain guiding significance for the future geological prospecting work in this area.
