尼日利亚伟晶岩型锂矿成矿地质特征与找矿方法研究

Metallogenic geological characteristics and research on the prospecting method of pegmatite-type lithium deposit in Nigeria

尼日利亚地处西非克拉通和刚果克拉通之间,经历了多期碰撞造山和变形变质作用,已发现多处伟晶岩型锂矿床,具备良好的锂多金属矿床找矿潜力。本文通过系统地分析尼日利亚成矿地质特征,结合国内外有关伟晶岩型锂矿床勘查手段,研究其找矿方法,以期指导该地区伟晶岩型锂矿的经济快速找矿。

Nigeria is located between the West African craton and the Congo craton.It has experienced multi-stage collision orogeny and deformation metamorphism.Several pegmatite-type lithium deposits have been discovered,which have good prospecting potential for lithium polymetallic deposits.In this paper,I will systematically analyzing the metallogenic geological characteristics of Nigeria and combining with the exploration methods of pegmatite lithium deposits in china and abroad,the prospecting methods are researched in order to guide the rapid and economic prospecting of pegmatite-type lithium deposits in this Nigeria.
