The role of ancient volcanic crater of ore-controlling structure and exploration direction in south of Song county

Abstract：The south of Song county is a part of gold metallgonenic belt of bear ear and waifang mountain, in which tectonic activities, areal alteration, migmatization and megma activities are stong.It has good metallgonenic geological condition in gold field.The gold ores (spots) mostly distribute in the third class volcanic tectonic belt, which hold about 82%.The activities of mantle plume provide the energy and material source for metallogenesis in south of Song county.The structure of volcano in old and mid-proterozoic era is the best low structure room of metallogenesis, which is a good prospecting target.
