摘    要：本文采用野外矿床地质调查及室内近代岩矿测试方法,研究矿床中的金银矿及与其密切共生的主要含金硫化物——黄铁矿、闪锌矿、方铝矿的标型特征,并运用自编的电算程序,计算了这些矿物的主要结晶学参数。通过分析对比,获得了一些层控火山沉积中低温变质热液型金矿的成因信息。

Abstract: The deposit concerned is a large gold deposit expored recently in HenanProvince. It can be opencut mined because of its shallowness. The associtedsilver, lead, zinc etc. are valuable in comprehensive utilization. The genesisof the deposit has its features and attracts the attention of geologists. Thispaper describes the typical characteristics of the gold and silver minerals andthe main gold-containing sulphide closely associated with it-pyrite, sphalerite,galena. The author calculated the principal crystallographic parameters ofthese minerals by using herown computer program and obtained some geneticinformation of mid-low temperature metamorphic epithermal gold deposit instrata-bound volcano deposit.
