埃塞俄比亚南部某风化壳型钽铌矿床地质特征

摘要

Through the summary of geochemical anomalies , geology of mining area and deposit characteristics of a weathering crust type tantalum niobium deposit in southern Ethiopia , its ore bodies , ore characteristics , genesis and ore controlling factors have been studied .It is pointed out that a lot of good anomalies in this area have not been veri -fied, a large number of ore bearing granite pegmatites , and ore bearing granite in deep part has not been controlled comprehensively .Through further work , the district is expected to find larger scale weathering crust type , pegmatite type and granite type tantalum niobium deposit .%通过总结埃塞俄比亚南部某风化壳型钽铌矿区域地质、重砂化探异常、矿区地质、矿床特征，重点探讨了该类矿床的矿体、矿石特征、矿床成因及其控矿因素等，指出该区还有很多较好异常未得到验证，大量的含矿花岗伟晶岩、深部含矿花岗岩也未得到全面有效的控制，通过进一步工作，该区有望找到规模更大的风化壳型及其伟晶岩型、花岗岩型铌钽矿床。
