Metallogenic conditions analysis and prospecting direction study in Kangbao area of Northwest Hebei

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.
