摘要
刚果(金)马诺诺地区地处基巴拉稀有金属成矿带,成矿地质条件优越。本文通过对该区稀有金属矿床成矿地质背景、典型矿床特征分析,总结了该区的成矿规律。结果表明,区域性断裂控制了该区的构造格局及矿产分布,具有明显的带状分布特征;岩浆活动强烈,其中尤以G4期岩浆侵入活动与稀有金属成矿关系密切;地层中的云母片岩类岩石提供良好的封闭条件,此3种要素的耦合有利于促使该区形成稀有金属矿床。
Manono area is located in the Kibara area metal ore belt with superior metallogenic condition.This paper deals with geological and metallogenic background of rare metal deposits in the area and characteristics of the typical deposits and summarizes the metallogenic regularity.Regional faults control structural frame and distribution of mineral resources of Manono area.The area is characterized by strong magmatism and belt-distribution of the deposits.Magmatic intrusion of stage G4 is closely related to the rare metal deposits.Mica schist provides sealing condition.Coupling of the above mentioned 3 factors facilitates formation of rare metal deposits.
