摘要: 苏丹萨拉州B12区块属努比亚地盾的一部分,区域主要岩石和水系沉积物中Au、Ag、Mo、Sn和稀有、放射性元素富集,变异特征明显,形成了NW向、NE向展布的3个异常带。详细分析了区域地区化学特征,划分出3个Au、Ag、Mo、Sn、稀有、放射性成矿远景区,预测中型金多金属矿床1个,有色金属、稀有、放射性小型矿产地各2处。

关键词: 水系沉积物, 地球化学特征, 找矿远景区

Abstract: The No.B12 block in Kassala,Sudan is one part of Nubian Shield,Au,Ag,Mo,Sn and Rare elements and radioactive elements are enriched in region major rock and stream sediments,variation characteristics of them is obvious.3 abnormal belts in the NW and NE directions are formed.Based on the analysis of regional geochemical characteristics,three prospective areas of Au、Ag、Mo、Sn,rare elements and radioactive elements are delineated and one medium gold polymetallic deposits and two each miniature non-ferrous,rare and radioactive deposits are found.

Key words: Stream sediments, Geochemical characteristics, Prospective areas
