摘要
The Transient Electromagnetic Method（TEM）was used to detect geological information of concealed sandstone type uranium deposits in Mahuangquan area. TEM surveying data were processed to divide structural units of the basin base, stratigraphic formation and sedimentary environment were analyzed, and faulted structure was interpreted. Subsequent drilling result shows a good application effect, and hence this method can provide effective geological data for sandstone type uranium deposits in the basin. It is held that the interpreted slope area and alluvial fan can be regarded as the key places for further ore-prospecting work.
