吉林省桦甸市马家店金矿矿床地质特征及找矿前景分析

Geological characteristics and prospecting prospect analysis of Majiadian gold deposit in Huadian City, Jilin Province

马家店金矿区位于吉林省著名的夹皮沟金成矿带上,是近年来夹皮沟地区发现的一座中型蚀变岩型金矿床。矿体产于蚀变二长片麻岩与北西向破碎带的接触部位,空间分布明显受北西向构造控制,矿体呈似层状及透镜状沿蚀变带分布。通过对本区成矿地质背景、矿体地质特征的研究,对本区找矿前景进行潜力分析。

Majiadian gold mine is located in the famous Jiapigou metallogenic belt of Jilin Province, which is a medium alteration rock type gold deposit found in Jiapigou area in recent years. The ore body is produced in the contact part of the altered monzonitic gneiss and the northwestward fracture zone, and the spatial distribution is obviously controlled by the northwestward structure, and the ore body is distributed in the shape of layered and lenticular along the altered zone.Through the study of metallogenic geological background and geological characteristics of ore bodies in this area, the potential of prospecting prospect in this area is analyzed.
