摘要
Based on the study of the coal-bearing basins in north China,we researched the material radioactive anomalies of drillings and aerial energy spectrum in the basins,analysed the ore-bearing features,and established the model stratigraphic sequence of the sandstone-hosted uranium deposit.It is suggested that the uranium deposit form in a deoxidizing environment,and it is grey sandstone form in deoxidizing environment that is the goal stratum for drill prespecting.In different geological period,different latitude environment evolving and basin tectonic position control the ore-forming process.
