贵州大坪子金矿找矿潜力分析
|
摘要
贵州大坪子金矿位于滇黔桂"金三角"之晴隆-罗平金矿带中部,属南盘江-右江成矿区北部的晴(隆)-兴(仁)-贞(丰)-罗(平)Au-Hg-Sb-Tl-U-萤石成矿带的核心部位,毗邻泥堡断控特大型金矿床。研究认为大坪子金矿区存在与区域金矿赋存规律一致的岩石、构造组合,并具Au、Hg、As、Sb等元素异常组合,且存在细粒浸染状黄铁矿化、硅化、白云石化、砷矿化等蚀变,均显示出矿区具有良好的找金潜力。
Dapingzi gold deposit,located in the central part of Qinglong-Luoping gold belt of Golden Triangle of Yunnan,Guizhou and Guangxi,belongs to the core part of the Qing( Long)-Xing( Ren)-Zhen( Feng)-Luo( Ping) Au-Hg-Sb-Tl-U-fluorite metallogenic belt in the northern part of Nanpanjiang-Youjiang metallogenic area,adjacent to a large gold deposit in the mudcastle. It is considered that there are rock and tectonic assemblages consistent with the occurrence of gold deposits in Dapingzi gold deposit area,with abnormal combination of Au,Hg,As,Sb and other elements,and there are fine-grained disseminated pyrite mineralization,silicification,dolomitization and arsenic mineralization,which shows great gold potential in the mining area.
