摘　　要：文章在对苏丹东北部金矿区域构造背景、含金建造及金地球化学特征研究成果的基础上,分析了哈塞、洁比特、瑞达和哈马迪等4个研究程度较高的典型金矿床的矿体赋存规律、矿床类型和金矿石的结构构造等特征,认为该地区至少存在石英脉型、火山成因块状硫化物和韧性剪切带等3种以上金矿床类型。金矿床的形成与岩石建造、构造作用关系密切,总结了苏丹东北部的金成矿规律,提出了在苏丹东北部沙漠覆盖区采用遥感、区域化探等新技术开展金矿勘查的思路。Based on the regional tectonic setting, gold-bearing formation and geochemical characters of gold mines in Northeast Sudan, we have analyzed ore-body occurrence regulations, deposit types and their structural characteristics of four representative gold deposits that are well studied,i, e. the Hassai, Gebeit, Rida and Hamadi gold mines. It is suggested that at least there are three types of gold deposits in this region, which are quartz vein, duc- tile shear zone and volcanic massive sulfide （VMS） types. The gold mineralization is in close connection with host rock formations and tectonics. We propose a new approach for surveys of gold deposits in deserts of Northeast Sudan by using remote sensing and geochemical exploration.
