Erlian Basin includingthe Manite Depression is characteristic of episodic rifting in the Early Cretaceous. Different stages of rift episodes control the vertical distribution of uranium reservoir and sandstonetype uranium deposits. In the western Manite Depression, advantageous orebearing sequences and uranium reservoir and the forming process of sandstonetype uranium deposits are all closely related to the episodic rifting in the Basin. Saihan Formation is the advantageous uranium reservoir bearing sequence which is in the transition stage from fault depression to sag;Late of episodic rifting usually accompany with weak episodic tectonic inversion.Multiepisodes weak tectonic inversion result in structural slope which contol the paleohydrogeology and the mineralization;Unconformity surface and denudation between different rifting episodes are control factors of the development of the oxidized zone and sandstonetype uranium deposits; Different stages with different features of episode rifting decide the space and time disposition of oilgas,coal and sandstonetype uranium deposits,which participate in sandstonetype uranium mineralization.According to different structural and depositional features of different stages of episodic rifting,we can determine key exploration sequences and prospecting types and favourable prospecting areas.
