摘要
胶东西部地区是我国重要的石墨矿勘查开发基地,已开发利用多年。本区石墨矿属沉积变质成因,分布于荆山群地层中,受构造控制明显。总结区内石墨矿床特征,结合区域地质、物探特征及已知矿区石墨矿规律,对本区石墨进行了分带、分区,采用趋势外推法和类比法对石墨矿资源预测,预测区内可新增334?类石墨矿物量4632万t,显示有良好的勘查开发前景。
Western Jiaodong area is the important graphite ore exploration development base of China,where has been developed for many years.The genetic type of this graphite ore is sedimentary metamorphic,which mainly distributed in jingshan formation,and controlled by structure.Through summarizing graphite deposit features in the studied area,combining with regional geological,geophysical characteristics and the metallogeny of known graphite ore mining area,the zones and areas of graphite in this region are divided,redicted resources of graphite ore through the trend extrapolation method and analogy method.There can be increased by 46.32 million tons of 334？ graphite mineral in region of prognosis,showing good exploration prospects for development.
