Geophysical criteria for ore prospecting volcanic type uranium deposits in Xiangshan area

As the most important uranium orefield of volcanic type in China, Xiangshan has been established as one of the integrated exploration areas in second batch by the Ministry, of Land and Resources. Some geophysical features for prospecting uranium deposits were summarized in gravity anomaly, aeromagnetic anomaly and airborne radioactivities anomaly, and ways of the geological- geophysical criteria for further prospecting the volcanic type uranium deposits have been set up in Xiangshan area by combining with the geological elements.
