山东三山岛-新立-仓上金矿床构造叠加晕特征浅析

摘要

Sanshandao-Xinli-Cangshang gold deposit is the important part of Zhaoye gold deposit.Its surface and shallow resources would dry up constantly,as more than 10 years of mining.It is particularly important to carry out the deep and periphery prospecting work using advanced technology in mining.This study adopted a new method of structural superimposed halos to predict the blind ore-body,established the structural superimposed halo model, and emphatically analysis the characteristics of structural superimposed halo’s key elements in the different middle ore deposit.Results of blind ore prediction show that 28 target areas have been preliminarily put forward in Sanshandao gold deposit, and the depth of main orebody predicts metal quantity of 35 234 kg;14 target areas have been preliminarily put forward in Xinli-Cangshang gold deposit,and the depth of main orebody predicts metal quantity of 52 189 kg,better prospecting effect was obtained.%三山岛-新立-仓上金矿是招掖金矿带的重要组成部分，矿山经过10多年的开采，其地表及浅部资源不断枯竭，因此采用先进技术开展矿区深部及外围找矿工作显得尤为重要。本次研究采用构造叠加晕新方法对三山岛-新立-仓上矿区深部及其外围进行了盲矿预测，建立了金矿床的构造叠加晕模式，并重点分析了矿床不同中段主要元素的构造叠加晕特征。本区盲矿预测结果显示：在三山岛金矿初步提出了28个盲矿预测靶位，其主矿体深部预测金金属量为35234 kg；在新立-仓上金矿初步提出了14个盲矿预测靶位，其主矿体深部预测金金属量为52189 kg，取得了较好的找矿效果。
