Objectives：The sedimentary facies types of the favorable oreforming sand bodies of the Houshigou Formation are preliminarily discussed under the guidance of the metallogenic theory of sandstonetype uranium deposits, combined with a small amount of sample analysis and thin section identification work,through the comprehensive utilization of outcrop and borehole data in the north of Hegang Depression. Methods：In this paper, the main petrological characteristics, sedimentary facies types and distribution characteristics of the Lower Cretaceous Houshigou Formation in the study area are comprehensively studied. Conclusions: It is shown that: ①The sand bodies of the Houshigou Formation are mainly feldspathic lithic sandstones and lithic sandstones, which are mainly continental freshwater sedimentary environments with high reduction capacity; ②The Houshigou Formation in the study area is mainly fan delta sedimentary environment, and is divided into six microfacies: braided channel, floodplain swamp, underwater distributary channel, estuary bar, sheet sand and distributary bay; ③The submerged braided channel sand body of the Houshigou Formation can be used as a key type for searching for phreaticoxidizedtype sandstoneuranium deposit, while the underwater distributary channel sand body is the main type for searching for interlayeroxidizedzonetype sandstone uranium deposit.
