摘　　要：乌尔禾地区位于准噶尔盆地西北部,属于构造活动及后期构造活化相对平静的地区。通过对该区进行铀资源区域评价,在白垩纪地层中发现了层间氧化带及铀矿化。简要介绍了该区围岩、地下水的补-径-排机制、古水文条件及地下水化学和地球化学特征,总结出有利的铀成矿区段为克—夏断阶带以西山前地段。Wuerhe district is located in the northwestern part of Junggar Basin, Xinjiang. It belongs to a relative quiet area without the obvious tectonic activities and obvious subsequent tectonic activization. Through the regional uranium resources evaluation on this area, the inter-bedded oxidation zone and uranium mineralization are discovered in Cretaceous. The wall rock, the rechargerunoff-discharge mechanism of groundwater, palaeo-hydrological condition, hydrological and hydrogeochemical features of groundwater are introduced briefly, the favorable uranium ore-forming segment is summarized to be located in the fore-mountain area to the west of Ke-Xia fault terrace zone.
