贵州西南部卡林型金矿构造控制与找矿方向探讨

研究区位于中国重要成矿区带南盘江-右江成矿区北部卡林型金矿富集区,自1978年在册亨县板其首次发现本类型金矿以来,经过40年的找矿勘探,先后查明一批大中型至超大型金矿床,累计查明金资源储量近700 t,并逐步深化成矿认识。本文从构造控矿入手,结合勘查实际,在对金矿分布与构造的相关性进行总结与分析的基础上,划分了10个金(锑)控矿构造带;据已知矿产地的相对集中分布,圈定16个矿集区;在简要成矿分析基础上,预测了25处找矿靶区,以期为下步探边摸底、攻深找盲扩大资源规模,早日建成我国千吨级黄金基地提供参考。

Discussion of Tectonic Control and Prospecting Orientation Karlin-type Gold Deposit in Southwest Guizhou

The target area is located in karlin-type gold enrichment region of Nanpanjiang-Youjiang metallogenic zone which is the important metallogenic zone in China.In 1978,since the the first discovery of this kind of gold deposit in Banqi of Ceheng,by 40 years’prospecting and exploration,many large,middle or super-large scale gold deposit were identified,the Cumulative identified gold resource is almost 700 ton,the metallogenic understanding is deepened step by step.In this paper,in the angle of tectonic ore-control,for the prospecting reality,on the basis of summarize and study the correlation of gold distribution and structure,10 gold(antimony)structural ore-control belt are divided.According to the relatively centralized distribution of known orefield,16 ore enriched zone.On the basis of simple metallogenic analysis,25 prospecting targets are predicted,so it will be helpful for further mass exploration and kiloton class gold base building.
