豫西灵湖金矿床地质特征及资源前景分析

Analysis on geological characteristics and resources prospects in Linghu Gold Deposit,Western Henan

总结近年来在灵湖金矿区所进行的地质勘查工作,分析矿区地层、构造和岩浆岩特征,研究矿区的控矿因素及矿体分布规律,认定该矿区深部依然具有良好的成矿地质条件。通过对矿化蚀变规律及矿脉空间分布特征的对比分析,提出成矿的有利地段主要位于F1与F5含金断裂构造蚀变带深部交汇部位和F5含金断裂构造蚀变带产状变化部位,并对矿区深部金资源量进行了预测。

The paper summarizes recent years＇ geological exploration work in Linghu gold mining area, analyzes the characteristics of the strata, structure and magmatic rocks, and studies the oreontrolling factors and the distribution regularity of orebodies in the mining area,identifying that the deep mining area still has favorable metallogenic geological conditions. By comparative analysis on mineralization alteration rules and spatial distribution characteristics of the lode, the paper purposes that favorable metallogenic sections mainly are located in the deep contact zone of F1 and F5 gold-bearing fracture alteration belts and the occurrence transfer part of F5 gold fracture alteration belt, and makes prediction of gold reserves in the deep mining area.
