Abstract: The newly discovered Xianghe crystalline graphite deposit is located in the Qinling-Dabie orogenic belt, hosted in Neoarchean-Paleoproterozoic Douling Group Xianghe gneiss. 33 crystalline graphite ore bodies have been circumcribed here and the mineral content is preliminarily estimated to be a massive scale. This paper discussed the genesis of the deposit and summarized the prospecting criteria on the basis of the metallogenic background, Geological features of the ore deposit, geochemistry of mineral deposits and geochemistry characteristics, and the occurrence state and characteristics of ore mineral. Research shows that the ore-bearing rock is graphite-bearing plagioclase gneiss. The Carbon sources of the graphite deposit are derived from organic matter. Comprehensive studies of the Xianghe crystalline graphite deposit show that the genetic type of the deposit is regional metamorphic-type graphite deposit, and it has a later distinctive hydrothermal and tectothermal transformation.
