石墨兼具非金属和金属的某些特性,是高、新、尖技术领域的原材料.中国石墨矿产资源具有"东多西少",尤其以黑龙江省最多,其中佳木斯地块石墨矿资源储量占黑龙江省石墨总储量的90%,佳木斯地块石墨矿床按石墨矿空间展布特征可划分为萝北石墨成矿带、双鸭山-桦南石墨成矿带和勃利-鸡西-密山-穆棱-林口石墨成矿带.佳木斯地块南缘为一套具孔兹岩特点的片麻岩-麻粒岩建造,属于中高压区域热流变质作用类型,以柳毛石墨矿床最为典型;北缘以低角闪岩相为主,局部达高角闪岩相,属于低压区域热流变质作用类型,以萝北云山石墨矿床最为典型.佳木斯地块区域变质型石墨矿床的碳质来源主要是由于富有机质地层经过变质作用形成,少数是由碳酸盐岩地层变质形成.%Graphite has some properties of nonmetal and metal and organic plastics, which serve as the raw material in the field of high, new and advanced technology.The graphite mineral resources in China have been more in the eastern part and less in the western part, especially in Heilongjiang Province.The graphite resources in Jiamusi block are accounted for 90% of total graphite reserves in Heilongjiang Province.According to the features of ore-bearing strata and tectonic metallogenic belt, the graphite deposits in Jiamusi block can be divided into Luobei graphite metallogenic belt, Shuangyashan-Huanan graphite metallogenic belt and Boli-Jixi-Mishan-Muling-Linkou graphite metallogenic belt.The southern margin of Jiamusi block are a set of gneiss-granulite formation with khondalite characteristic, which were the products of middle-high pressure regional thermal metamorphism, with the typical deposit of the Liumao graphite deposit.The northern margin of Jiamusi block are dominated by low amphibolite facies, with high amphibolite facies locally, which were caused by low pressure thermal metamorphism, with the typical deposit of the Luobei Yunshan graphite deposit.In the Jiamusi block, the carbonic matterof these regional metamorphic-type graphite deposits were mainly sourced from organicmatter-rich strata and were formed by metamorphism, with few of them were formed by the metamorphism of carbonate rock stratum.
