摘要
广西西大明山铅锌银多金属矿集区是广西重要的多金属成矿区,已发现有多处大—中型内生金属矿床,目前该地区仍然具有较大的找矿前景。文章系统总结西大明山矿集区构造控矿规律,初步得到以下认识:①西大明山矿集区具有三级构造控矿的特点;②北东向与近东西向构造复合部位对多金属矿床的形成起重要的控制作用;③断裂浅部的断坪部位为铅锌银多金属矿的有利富集部位,部分矿体具有明显的向南东侧伏的规律。
The lead-zinc-silver polymetallic ore concentration area of Xidamingshan is an important polymetallic metallogenic area in Guangxi. So far,several large-medium-scaled endogenous metal deposits have been discovered. However,this area still has great potential for prospecting. The structural ore-controlling laws of the Xidamingshan ore-concentrating area were systematically summarized and the following understandings were obtained:( 1) The Xidamingshan ore-concentrating area represents threeorder structural ore-controlling characteristics.( 2) The intersection part of northeast-oriented and nearly eastwest-oriented structures play an important role in controlling the formation of polymetallic deposits.( 3) The fault flat in the shallow part of fault is the favorable enrichment area for lead-zinc-silver polymetallic ore deposits and part of the orebody represent obvious lateral extensional law towards SE direction.
