山东谢家沟矿区金矿体地质特征及其深部资源详查评价

谢家沟金矿区为黄铁绢英岩化蚀变糜棱岩型金矿床。该区经多年勘探开发，资源含量不断减少，需要对其深部矿体进行详查评价，为矿山的进一步发展储备更多的后续资源。在简要介绍矿区和矿体地质特征的基础上，对谢家沟矿区深部金矿体进行详查研究。谢家沟矿区内含矿蚀变带较多，脉岩发育，今后的矿山地质工作应在分析成矿规律基础上，继续加强深边部地质探矿，为矿山的可持续发展提供必要的物质基础。随着采矿深度逐步下降、开采范围逐步扩大，应该加强矿床矿石特征的研究工作，进一步查清矿石特征和变化规律，为合理利用资源与改进选冶工艺提供依据。

The Geological Characteristics and Deep Resources Investigation Evaluation of Gold Orebodies in Xiejiagou Mining Area

Xiejiagou mine pyrite phyllic altered mylonite-type gold deposits.After many years of exploration and de- velopment in this area,resource reserves are declining,so detailed investigation and evaluation of the deep ore body is needed to reserve mine resources for further development.Basised on a brief introduction on geological character- istics and orebodies geological features,a presentation about deep gold body scrutinizing in Xiejiagou mining area is made.Mineral alteration zone and dike rock are developed in Xiejiagou mining area,it is necessary to strengthen the geological prospecting deep on the edge ,to provide necessary material basis for the continued development of the mine, on the basis of metallogenic regularity and mine geology analysis.With the gradual decline of mining depth, mining range gradually expanded,we should strengthen the research on characteristics of ore deposits within the fur- ther identification of ore characteristics and variation,to provide a basis for the rational use of resources and im- provement of dressing and smelting process.
