Abstract: Experiments on prospecting for concealed sandstone-type uranium deposits using the dynamic geogas method were conducted in a gobi desert region by deploying a survey line in each known sandstone-type uranium deposit and uranium ore occurrence. The results indicate that the dynamic geogas sampling technology with adjustable efficiency detected geogas anomaly zones above all known concealed sandstone-type uranium deposits. These zones were characterized by multiple adjacent anomaly peaks composed primarily of uranium (U) and multiple associated (paragenetic) elements, with widths approaching those of the surface projections in a range from the ore bodies with a burial depth of approximately 50 m to the boundaries of the ore bodies' overturning ends. Therefore, the geogas anomaly zones and their widths serve as important ore-prospecting indicators for concealed sandstone-type uranium deposits. The relationships of captured geogas anomalies with factors such as the depths and grades of ore bodies in the experimental area confirm that the dynamic geogas method with adjustable efficiency can detect concealed sandstone-type uranium deposits at depths exceeding 756.4 m. The relationships also reveal that the amplitude of U geogas anomalies increases with the ore body grade and that the spacing between geogas detection points on the profile for sandstone-type uranium deposits should not exceed 50 m. The experiment corroborates that the geogas method is feasible and effective in detecting concealed sandstone-type uranium deposits in a gobi desert region.
