河南省大青一带地球化学特征及找矿前景

Geochemistry Characteristics and Prospecting Ore in the Daqing Area,Henan

河南省大青地区沿乔端-瓦穴子断裂带和二郎坪群火神庙组分布着以银、铅、锌为主的带状异常,过去未引起重视。通过地质大调查项目实施,对本区地球化学特征进行了研究,并重点检查了以银、铅、锌为主的异常。在火神庙组的变石英角斑岩中发现了银、铅、锌多金属矿化带,伴生有金、铜等金属矿化,并对其成因进行了初步分析。鉴于区域上存在众多的以银、铅、锌为主的综合异常和相似的地质环境,找矿产潜力很大,随着矿产资源评价工作的全面展开,本区找矿定会有较大的发现和突破。

In the past several years, a series of geochemical Ag - Pb - Zn anomalies belts has been delineated in Daqing area of Henan province, which follows Qiaoduan - Waxuezi fault zone and Huoshenmiao formations of Erlangping group distribute, but it did not cause the value. During the General - Geological - In- vestigation, we did a lot of research work upon the geochemistry characteristics in this area, especially investigated the Ag -Pb -Zn anomalies, and discovered several Ag -Pb -Zn metallogenic belts associated Au - Cu metalizafion in the meta - quartz keratophyre of Huoshenmiao formation. We analyzed about these gene- ses of the metallogenic belts. In this region, there are many Ag - Pb - Zn composite anomalies similar to it, and the geological environment is almost the same, so this area is a very great ore - search potential. Along ywith the mineral - resources - assessment work completely to launch, there will be certainly great discoveries and breakthrough of the ore - search work. in this area.
