| 摘 要： | 高技术产业、战略性新兴产业的迅猛发展,对新兴材料矿产提出了迫切需求,包括中国在内的世界主要国家均制定了符合自身利益和发展的战略性矿产目录。康保县作为当前河北省探矿的热门区域,研究其成矿条件、确定找矿方向对提高勘查效率、提升找矿成果尤为重要。通过查明研究区与全国主要成矿区带的位置关系,指出研究区位于多种矿产矿集区的结合地带; 对石墨、稀有金属、萤石及石英岩成矿条件与研究区地质背景对比分析,认为该区成矿地质条件优越; 开展野外调查,发现上述矿种矿化较强,地球物理和地球化学异常明显,具有较大的成矿远景。针对今后的找矿方向提出了具体建议: 石墨调查以东井子岩组和三夏天组为主; 稀有金属调查以海西期碱性花岗岩为主; 萤石勘查应结合地质背景和化探异常优选普查区; 高品质石英岩调查应以戈家营组和三夏天组为重点。

| Abstract: | With the rapid development of high-tech industry and strategic emerging industry, the demand for new materials and minerals is great. Major countries in the world, including China, have formulated strategic mineral catalogues in line with their own interests and development. Kangbao County is a hot prospecting area in Hebei Province at present, and it is particularly important to study the metallogenic conditions and determine the prospecting direction for improving prospecting efficiency and results. By ascertaining the positional relation between the study area and the major metallogenic belts in China, the authors pointed out that the study area is located in the conjunction zone of multifarious minerals concentration areas. Through comparing and analyzing the metallogenic conditions of graphite, rare metals, fluorite and quartzite and the geological background of the study area, the authors considered that the metallogenic geological conditions in this area are superior. By the field geological survey, they found that the mineralization of the minerals mentioned above is strong, geophysical and geochemical anomalies are obvious, and the ore-forming prospects are great. In view of the prospecting direction in the future, this paper provides specific suggestions: ①the graphite investigation should mainly focus on Dongjingzi Formation and Sanxiatian Formation; ②the rare metals investigation should focus on Hercynian alkaline granite; ③fluorite exploration should be combined with geological background and geochemical anomalies to optimize the overall survey area; ④the high quality quartzite investigation should focus on Gejiaying Formation and Sanxiatian Formation. |
