Bashenghe is located in Chaihe Basin, Da Hinggan Mountains uranium metallogenic belt. Previous research on uranium prospecting has been very insufficient. Based on an analysis of the characteristics of airborne gamma-ray spectroscopy of typical regional uranium deposits, the authors established the anomalous indicators of airborne gamma-ray spectroscopy in regional volcanic-type uranium mineralization areas: high-value field of uranium, high-value halo of uranium increment (Delta U), low-value halo of active uranium (Hu), and high-value halo of airborne F-parameter. In terms of these features, the airborne gamma-ray spectrum data of the study area were processed effectively, then anomalous characteristics were analyzed, and five airborne comprehensive anomalous halos were delineated. Combined with stratigraphic, structural and geophysical and geochemical conditions, the uranium metallogenic potential of the five airborne comprehensive anomalous halos was studied. Finally, the integrated anomalous halos formed by H01, H02 and H03 in the study area was found with good volcanic uranium metallogenic potential.
