The Huangling area on the southern margin of the Ordos Basin boasts great potential for uranium mineralization. China Geological Survey has organized and implemented 3D geological survey of the uranium-bearing rock series in this area to seek prospecting target areas of in-situ leachable sandstone-hosted uranium deposits. During the survey, the data of the coalfield boreholes were developed and utilized again to determine exploration areas under the guidance of new ideas of joint coal-uranium explorations and joint petroleum-uranium explorations. As a result, the data of 354 coalfield boreholes (49 potential sandstone-hosted uranium ore boreholes) and 21 verified uranium ore boreholes (16 industrial uranium mineralization boreholes) were acquired and a database was created accordingly. Furthermore, a thematic result atlas and a 3D geologic model were established, which mainly constitute the database. The thematic result atlas includes the isoline maps of stratum thickness, sand body thickness, the burial depth of the roof and floor, sand content and radioactive anomalies of the uranium-bearing rock series. Therefore, the database will provide active support and service for the exploration and development of uranium deposits.
