陕西省石墨矿成矿特征及成矿区带划分

石墨矿是具有重要发展前景的原材料矿产。笔者对陕西省石墨矿床类型、成矿时代、矿床成因进行了分析归纳，认为陕西省石墨矿产资源具有类型齐全、矿石质量有明显差异的特点。对陕西省石墨矿典型矿床进行了分析，对成矿规律进行了总结，认为区域变质型为晶质石墨矿重要成因类型，岩浆作用、混合岩化作用对石墨矿物片度增大有促进作用；接触变质型为隐晶质石墨重要成因类型，矿体分布在岩体外接触带，规模较小。根据成矿条件对陕西省石墨矿成矿区带进行了划分，指出了陕西省石墨矿进一步找矿方向。

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.
