Major deposits and occurrences of platinum ores of the Kola belt layered intrusions (Kola Peninsula, Russia)

Abstract

Research subject. This paper presents data characterizing major occurrences and deposits of platinum group elements (PGE) of Kola belt layered mafic-ultramafic intrusions (Kola Peninsula).Materials and methods. The study was based on extensive experimental data collected by the author over a long-term period and a comprehensive analysis of published and archive literature pertaining to this field.Results. Certificates (so-called passports) were compiled for all major PGE objects in theKola Peninsula, which include diverse characterization parameters (geological, structural, isotope-geochemical, mineralogical). The formation of PGE mineralization was compared with both the age characteristics of large layered complexes and the sequence of intrusion of individual magmatic phases.Conclusion. The proposed parameters can be used to determine specific features of PGE objects, thus allowing identification of objects promising in terms of industrial development. The obtained results demonstrate the importance of taking into account these specific features during mineral deposit exploitation.
