摘　　要：本文运用水成铀矿地质理论 ,对乌兰花盆地上新统铀矿成矿的区域地质背景、铀源条件、岩性岩相古地理、砂体特征和水文地质条件进行了初步分析 ,认为该盆地上新世具备古河道的发育条件 ,上新统是主要的找矿目的层位之一 ,具备形成古河道砂岩型铀矿的成矿条件 。Using the geologic theory of hydrogenic uranium deposit,ore formation conditions of uranium,such as regional geologic setting,uranium source,lithology,lithofacies and paleogeography,characteristics of sand bodies,as well as hydrogeologic conditions are analysed in this paper.It is suggested,that the Pliocene series of the Wulanhua basin is favourable for the development of paleochannels and must be the main prospecting target horizon possessing ore formation conditions for paleochannel sandstone type uranium deposits.At the same time,there are some unfavourable factors for the formation of sandstone type uranium deposits.
