摘　　要：根据铀成矿作用及铀矿体的产出特点分析,认为东胜铀矿床孙家梁和沙沙圪台地段铀成矿过程明显受铀储层的古层间氧化作用、后期改造及还原保矿作用的控制。研究表明,由于不同地段的控制因素存在差异,造成铀矿化特点不一致。因此,掌握不同地段的控矿因素,有助于判断古层间氧化带前锋线的产出位置,对扩大东胜铀矿床规模、预测富铀矿体产出部位以及区域找矿具有指导意义。By analyzing uranium metallogenesis and ore orebody distributing characteristics,the paper suggested that the uranium mineralization in Sunjialiang and Shashagetai tract of Dongsheng uranium deposit is influenced by paleo-interlayer oxidation,later-modification and later-reductive ore preser-vation in the hosting strata.It was founded that the mineralization controlling factors are different in different area.Therefore it is helpful to define the paleo-interlayer oxidation front through correctly discriminating these factors in different area,and it will play a guild role in expanding the deserve of Dongsheng uranium deposit,predicting the high grade orebody and regional exploration.
