摘要
吉德金矿矿体主要呈似层状、透镜状产于峨眉山玄武岩与下伏灰岩岩溶不整合面、玄武质火山碎屑岩夹层及次级构造破碎带中,有红土型和岩溶角砾岩型两种类型,金以微粒自然金为主,目前矿床规模较小、地质研究程度较低.通过总结成矿规律、构建成矿模式,对矿区及外围寻找红土型和岩溶角砾岩型金矿具有指导作用.
Abstract
The Jide gold deposit mainly occurs in a layered and lens like manner in the unconformity between Emeishan basalt and underlying limestone karst,interbedded with basaltic volcanic clastic rocks,and secondary structural fracture zones.There are two types of gold:laterite type and karst breccia type,with the main type of gold being fine natural gold.At present,the scale of the deposit is relatively small and the degree of geological research is relatively low.The summary of ore-forming laws and the construction of metallogenic model provide guidance for the search for laterite type and karst breccia type gold deposits in the mining area and surrounding areas.
