山西右玉火烧滩—后窑子一带水系沉积物地球化学特征及找矿应用效果

Geochemical characteristics of stream sediments in Huoshaotan-Houyaozi area of Youyu County,Shanxi Province and their prospecting application effect

为查明研究区区域地球化学异常、缩小找矿靶区以及进一步找寻原生金矿,在山西右玉火烧滩-后窑子一带开展1∶[KG-*3]5万加密水系沉积物测量工作,完成面积43.89km^(2),圈定单元素异常58个,综合异常13个,金异常16个。对区内Au8、Au5、Au9等主要金异常进行异常查证,发现火烧滩和后窑子两条重要金矿(化)带,经进一步开展矿区金矿地质勘查工作,圈定9个金矿(化)体,提交金矿产资源量达中型规模,实现了该地区近十年来地质找矿工作的新突破。

In order to identify regional geochemical anomalies in the study area,narrow the prospecting targets and explore primary gold deposits furtherly,1∶50000 encrypted measurement of stream sediments was carried out in Huoshaotan-Houyaozi area,and 43.89 km^(2)was completed.Through this work,58 single element anomalies,13 comprehensive anomalies and 16 gold anomalies were identified.By verifying the main gold anomalies such as Au8,Au5 and Au9 in the study area,two important gold(mineralized)belts,Huoshaotan and Houyaozi were found.Furthermore,9 gold(mineralized)bodies have been identified through the geological exploration of gold deposits in the mining area,and the amount of gold mineral resources submitted has reached medium-sized scale,which realizes a new breakthrough in geological prospecting in the region in the past decade.
