Abstract On the basis of the comprehensive analysis of regional geological background, ore-bearing belts, ore body, ore-bearing formation, modification and deformation, as well as migmatization, the authors summarized the metallogenic characteristics of graphite deposits in Bashang area of Northwest Hebei. Through the comparison between typical regional metamorphic graphite deposits and adjacent graphite deposits in the same metallogenic belt, on the basis of the evolution law of regional tectonics, the authors summarized the metallogenic model of graphite deposits in this area. According to the “trinity” prospecting theory, they summarized the metallogenic characteristics of geological bodies, structures and graphite deposits in this area, and built the comprehensive prospecting pattern of crystalline graphite deposits. The graphite deposits in this area are stratiform, and exist in the graphite-bearing granulite of Hongqiyingzi rock group. The distribution of metallogenic belt is controlled by large-scale compound folds. The sedimentary period of ore-bearing formation is early Paleoproterozoic, and the metamorphic metallogenic period is middle Paleoproterozoic. The metamorphic degree is amphibolite facies, and the genetic type belongs to a regional metamorphic type. Because the study area is in a shallow-covered condition, the geophysical anomaly of “low resistivity-high polarization” is an important geophysical prospecting indicator. It is a rapid and effective method to explore the graphite deposits in this area by means of geology-geophysics-drilling combination.
