Abstract: Based on the characteristics of airborne radioactivity survey anomaly，gravity and magnetic measurement anomaly，electrical measurement anomaly and the seismic reflection characteristics of sandstone-type uranium deposit in Erlian basin and combined the metallogenic regularity and conditions of sandstone-type uranium metallogenic deposits，a set of eye-catching prospecting indicators in the sandstone-type uranium deposits are deduced.It is confirmed that the areas surrounding γ high anomalies can be the source of uranium or directly the location of uranium deposits；The fault structures are the storage and the transport (H₂S，hydrocarbons)channels for reducing materials (carbon dusts).It usually tends to form an oxidation-reduction zone in the surrounding strata of the favorable uranium metallogenic tectonic fracture.The sag slopes provide favorable hydrodynamic conditions for sandstone-type uranium mineralization，and it usually tends to form the uranium ore belts or uranium deposits in the regions of sag edge.In addition，through the methods of detailed analysis，and comparing with the characteristics of airborne radioactivity survey anomaly，gravity and magnetic survey anomaly，the electrical measurement anomaly and the seismic reflection，it is found that the geophysical method can be used to describe the basal and sediment (mainly sand stone and mudstone)shapes and analyze the sedimentary facies so as to obtain the metallogenic environment and metallogenic regularities of sandstone-type uranium.
