| 摘 要： | 本文着重从盆地构造演化这一角度出发，论述了盆地构造演化对盆地结构、沉积充填序列、水文条件、铀活化迁移等与盆地铀矿化作用关系密切的因素的控制作用，认为盆地构造为查干诺尔盆地铀矿化作用创造了有利的条件，控制了查干诺尔盆地铀矿化的成因类型、分布范围及矿化程度。受盆地构造演化特征的影响，盆地内铀矿化存在两种类型，即潜水氧化带型和局部性层间氧化带型。

| Abstract: | Starting from the tectonic evolution of the basin,authors expound the controlling role of the tectonic evolution of the basin upon factors closely associated with uranium metallogenesis in the basing such as the structure of the basin,filling sequence of cover deposit,hydrologic conditions and the mobilization and migration of uranium etc.It is suggested that the basin structure created favorable conditions for uranium ore-formation in Chagannuoer basin,it also controlled the genetic types of uranium mineralization,the distribution area and development intensity of uranium mineralization in the basin.Features of tectonic evolution resulted in the development of two type uranium mineralizations in the basin,i e.phreatic oxidation and local interlayer oxidation types. |
