The distribution characteristics and prospecting significance of areal geophysical field in Gan-Hang tectono-volcanic metallogenetic belt of uranium

Based on brief description of the fundamental characteristics of areal geophysical field in Gan-Hang tectono-volcanic metallogenetic belt of uranium, the author emphatically discusses several problems such as the spatial distribution relationship between areal geophysical field and uranium mineralization, various features of regional geophysical field for each typical uranium deposit (ore field) and their composite types. It is presented that the composite type of geophysical field in respect to 'multi-position in one body' should be the best one to uranium metallization. According to composite types, ore deposits (occurrences) are classified and arranged in order, providing the basis for the potential evaluation in the whole belt. Suggestions on the work in the future has thus been made
