摘　　要：本文介绍了盈江盆地的构造格架及构造分区、晚第三纪盆地沉积特征 ,对盆地盖层发育的氧化带进行分类 ,论述了氧化带的发育特征及其与铀矿化的关系。This paper introduces the tectonic pattern and tectonic division, sedimentary features of Late Tertiary, and the classification of the oxidation zone in sedimentary cover, and discusses development features of the oxidation zone and its relationship with uranium mineralization in Yingjiang basin. It is considered that the uranium mineralization types related with ground water interlayer oxidation zones, ground water interlayer paleo oxidation zones located above the water blocking faults are the main types of sandstone uranium deposits.
