贵州张维-五指山地区铅锌矿评价成果及意义

项目主攻矿种为铅、锌,主攻区域为张维—五指山地区铅锌矿化集中区,通过综合研究,采用地质、物探、钻探和坑道相结合的手段,重点对五指山地区那雍枝铅锌矿床和张维地区水东铅锌矿矿床进行解剖评价,估算了333+334铅锌金属资源量215.65万吨,其中333铅锌资源量52.03万吨,取得了很好的找矿效果;建立了五指山地区铅锌描述性综合信息找矿模型,经过成矿预测认为,五指山地区砂岩、落水岩、那润和喻家坝,张维地区的以则孔,果化地区的打麻厂和堰塘等,具有较好的找矿潜力,值得进一步开展地质工作;经过后期勘探,建设3个中型矿山,增加了当地居民和地方财税收入,在乌蒙山贫因地区具有经济和社会意义。

Achievements and Significance of Lead-Zinc Exploration in Zhangwei-Wuzhishan Area of Guizhou Province

In this project, we selected lead and zinc as the main exploration target, and the working area located in concentration zones of lead-zinc deposits from Zhangwei to Wuzhishan. On the basis of synthetic study, using the integrated geological and geophysical methods, combining with drilling and tunneling projects, the Nayongzhi deposit of Wuzhishan area and the Shuidong deposit of Zhangwei area have been explored. The prospecting effect was quite good that we estimated 333+334 lead zinc metal resources 2,156,500 tons, in which 333 lead zinc resources 520,300 tons. On these bases, we established the prospecting model of lead-zinc deposits in Wuzhishan area, forecasted that the prospecting area distributed in Shayan, Lishuiyan, Narun and Yujiaba of Wuzhishan area, Yizekong of Zhangwei area, Damachang and Yantang of Guohua area; and proposed that these area were worth of further exploration. After the late stage exploration, 3 medium mines were constructed, and local residents’ income and local government’s financial revenue were increased. This project has economy and social significance to Wumengshan poverty area.
