Abstract
Ore deposits related with mafic-ultramafic mantle magmatism contain sulfide Cu-Ni ± PGE deposits, but in many cases without PGE. Reasons for such a difference in mafic-ultramafic mantle magmatism are most often not studied, but tectonic petrological understanding of this phenomenon requires explanation, both from a scientific point of view and for economic purposes, particularly since such deposits are of strategic importance. In the proposed paper, an attempt is made to provide a petrological tectonic and isotope geochemical explanation of the reasons for possible lack of platinum group elements for sulfide Cu-Ni ± PGE deposits.
