Metallogenic Characteristics and Mineralization Zoning of Granite Deposits in Shaanxi Province

The graphite is an important raw material, with good development prospect. After analyzing the types, metallogenic age and genesis of the graphite deposits in Shaanxi Province, it's concluded that Shaanxi Province has all kinds of graphite deposits, but they are obvious differences in ore quality. In this paper, the typical graphite deposits in Shaanxi have been analyzed, and their metallogenic regularity has been summarized. The results show that the regional metamorphic type serves as the most important genetic type for the crystalline graphite deposit, while the magmatism and dolomitization can improve the degree of graphite minerals. The contact metamorphic type is an important genetic type for the aphanitic graphite deposits, and the orebody is distributed in the outer contact zone of rock mass, with small scale. According to the metallogenic conditions, the mineralization zone of graphite deposits in Shaanxi Province has been divided, and the further direction for prospecting graphite deposits in Shaanxi Province has been pointed out.
