中文摘要:
      石墨是新型产业发展的重要原材料,随着社会飞速发展和科技进步,工业需求量急剧上升。目前,随着矿床开采技术和勘探技术的提高,寻找分布于地表浅层次的、高品位的石墨矿床难度愈发明显。在系统总结含矿岩系时空分布特征和区域成矿规律基础上,在含石墨岩系的“老”矿区深部及其外围露头条件差的地区开展盲矿体寻找,将是取得找矿突破的有效途径。对蒙西南—冀北含石墨矿带勘查与区域地质资料综合分析表明,该矿带位于华北陆块北缘,变形构造发育,区域变质、混合岩化强烈,含矿岩石是新太古界孔兹岩系,已在露头较好地段发现大、中、小型晶质鳞片石墨矿多处,具有良好的区域变质石墨矿成矿地质条件与找矿潜力;覆盖区是该成矿带寻找新的石墨矿床的有利目标区。
英文摘要:
      Graphite is one of the important raw materials for the development of new industries. With the rapid development of society and scientific and technological progress, such that the demand in industry has sharply increased.At present, with the improvement of mining technology and exploration technology, it is more and more difficult to find high grade graphite deposits distributed in the shallow layers of the surface. On basis of summarizing the spatial and temporal distribution of ore-bearing rock series in the system and regional metallogenic regularity, exploration in the "old" fields of graphite-bearing rock series of deep and periphery of blind orebodies in the areas of poor outcrop conditions will be an effective way to prospecting breakthrough. Comprehensive analyzing on graphite ore belt exploration and regional geological data in Mongolia western south and Hebei north shows that the mine zone locates in the northern margin of north China landmass, deformation structure development, regional metamorphism and migmatization strongly, ore-bearing rock is the archaean group exhibited rock series, which has been found in large, medium and better outcrop section several small crystalline flake graphite mine, where they have the good regional metamorphism of graphite ore metallogenic geological conditions and prospecting potential of coverage area of metallogenic belt, which is the search for new graphite deposit the favorable target area.
