%X Based on an analysis of the metallogenic conditions of the sandstone type uranium deposit in Quantou Formation within southern Songliao Basin, this paper holds that semi-arid subtropical paleo-climate was favorable for uranium mineralization. Fluvial and deltaic sediments provided space for the development of thick and large sand bodies. These sand bodies are well developed in Quantou Formation, with the monolayer of the sand body reaching over 40 meters in thickness. Though organic carbon content was low in sand bodies, hydrocarbon in coal-bearing layers under Quantou Formation probably migrated upwards into sand bodies along faults and sur-faces of the unconformity and increased the capability of the reducing agent. The discovery of industrial uranium ore bodies suggests large-scale uranium enrichment. Therefore, the Quantou Formation may be regarded as an important target layer for sandstone type uranium exploration.
