Characteristics and Geochemical Anomalies of the Tarka Gold Deposit, Zimbabwe

Publish Date: 25 June 2013

摘要: 本文以津巴布韦塔卡金矿的区域地球化学资料为基础,对矿区地球化学特征、金成矿条件及找矿标志进行了分析,发现矿体主要赋存于元古宙Umkondo群的绢云石英片岩中,并受南北向区域构造控制。区内Au、W 、Hg 、Sb等异常共生组合元素,均可作为Au的找矿指示元素。通过对塔卡金矿的区域地质-地球化学异常特征和找矿标志的研究,建立了该金矿的地球化学异常模型及找矿标志,对已取得的1:25万区域化探异常的筛选和评价,以及进一步提高化探找矿效果,均具有一定的启示意义。

Abstract: The Tarka gold deposit lies in the eastern part of Zimbabwe Chimanimani area. The ore bodies are host-ed in the Proterozoic Umkondo sericite-schist and controlled by regional tectonic. The anomaly element associa-tion of the mainly Au、W 、Hg and Sb can serve as indicator elements in ore exploration. Based on regional geo-chemical data, the regional geochemical anomaly model and ore indications of the Tarka gold deposit have been set up, which is of positive significance for sieving and evaluation of 1:25000 regional geochemical anomalies and further improvement of the results of gold geochemical reconnaissance.
