The analysis of the occurrence mode and controlling factors of radial molybdenite in molybdenum deposits is of great significance for studying the formation mechanism of molybdenum deposits. In this paper, the radial molybdenite of Baimiaogou molybdenum deposit in the southern margin of North China block is taken as the research object. On the basis of field geological survey and petrographic observation, combined with laser Raman spectroscopy in situ test, the occurrence location, morphology, structure and symbiotic mineral assemblage of molybdenite are analyzed, and its controlling factors are discussed. Studies have shown that molybdenite mainly occurs in the micro-cracks of quartz minerals in medium and fine-grained monzonitic granite and altered andesite, mainly radial, and brittle tensile cracks related to overpressure are the main controlling factors.
