粤西某铌钽矿矿床地质特征及找矿标志

Geological Characteristics and Prospecting Indicator of a Nb-Ta Deposit in Western Guangdong Province

铌、钽作为重要的稀有元素,是我国较稀缺的金属矿产资源。以粤西某铌钽矿为例,结合矿区地质工作成果,分析了矿区地质背景及矿床地质特征,并总结了找矿标志。研究表明:构造、伟晶岩、蚀变、岩(矿)脉特征、地层、地表露头等为寻找铌钽矿的有利标志。

Nb and Ta are the important rare elements,they are the relatively scarce metal mineral resources in our country. Taking a Nb-Ta deposit in Western Guangdong Province as the study example,combing with the geological working results in the mining area,the regional geological background and geological characteristics of the deposit are discussed,besides that,the prospecting indicators of the deposit are summarized. The study results show that the favorable prospecting indicator of the deposit are structures,pegmatite,alteration and characteristics of rock veins and ore-body veins,strata and surface outcrop.
