摘　　要：鲁乎乎盆地东部斜坡带砂体发育且厚度较大,具备形成层间氧化带砂岩型铀矿的空间条件。鲁乎乎盆地具备二元结构,通过地质、伽马总量测量,研究了该区地层、岩性及构造发育特征,并圈定了多个放射性异常靶区;通过伽马能谱综合剖面及地表工程进行异常查证,确定了W-1、W-2、W-3和W-4为有利的异常区。通过进一步的研究和勘查工作,鲁乎乎盆地具备发现中-大型砂岩型铀矿床的潜力。The research area is in the slope zone of the east Ruhuhu Basin.The sand body of Ruhuhu Basin is very thick and well developed,and possess the space condition of forming the inter layer oxidation zone.There exists the dual structure in Ruhuhu Basin.The geology survey shows the characteristics of stratum,lithology and structure,andγgross survey targets some anomalies.By the gamma spectrometry survey and surface engineering,the W-1,W-2,W-3 and W-4 are determined as the favorable areas.The Ruhuhu Basin has a huge potentiality of formed medium and large scale sand-type uranium deposits.
