黑龙江石墨矿资源潜力预测

Potential prediction of graphite ore resources in Heilongjiang Province

在区域成矿环境及典型矿床研究的基础上,系统总结了黑龙江沉积变质型晶质石墨矿成矿特征,深入分析了成矿地质作用及控矿因素。建立了柳毛式沉积变质型晶质石墨典型矿床区域预测模型,在预测工作区圈定和优选了217个最小预测区,采用地质体积法估算石墨矿物的预测资源量。指出黑龙江石墨找矿潜力大,为今后石墨矿勘查部署提供了重要的地质依据。

Based on the analysis of regional metallogenic setting and typical deposits, this work systematically summarized the oreforming features of the sedimentary metamorphic crystalline graphite ores in Heilongjiang Province, and thoroughly analyzed the metallogenic geological process and ore-controlling factors. In addition, we established a regional prediction model for the Liumao-type sedimentary metamorphic crystalline graphite ores, delineated and optimized 217 minimum prediction areas, and estimated the graphite ore resources by the geological volume method. It is suggested that there is a great potential for prospecting graphite ores in Heilongjiang, which may provide important geological evidence for the future graphite ore exploration.
