Focusing on the PGE enrichment mechanism in the basic-ultrabasic intrusions in the Panxi rift, firstly, through the interpretation of TM photograph, data processing of regional geochemical exploration and geophysical prospecting results of gravity, magnetic force and seism, we analyzed the controlling effect of structure and magmatic movement on the PGE mineralization; Secondly, through the study of volcanic apparatus, petrography, measurement of comprehensive geochemical section, isotope tracing and dating of typical PGE-rich melanocratic rock series, we discussed the sources of the PGE-bearing mafic-ultramafic intrusions and basalts, their timing, evolvement sequences, the geochemical processes of magma crystallization and fractionation, and the relationship between magma evolution and structural development; Finally, through the analysis of PGE and chalcophile elements concentrations in the melanocratic rock series and the contrastive study with the Noril''sk magmatic Ni-Cu-PGE sulfide deposit, its related continental flood basalts and Siberia Traps, we discussed PGE mineralization characteristics and its enrichment mechanisms in the melanocratic rock series in the Panxi rift.
