Abstract - Summary 
(short description):
The gabbro–pyroxenite–dunite plutonic complexes in the Koryak Highland are typical of a regional palaeoisland arc system, that formed in the Late Cretaceous–Paleocene. The gabbro–pyroxenite–dunite plutonic complexes are allocated platinum (I - Pt), osmic-platinum (I – Pt > Os) and iridiñ-platinum (II – Pt > Ir) mineralogical-geochemical types. Minerals of platinum group of the I - Pt and I – Pt > Os types are magmatic-fluid-metacomatic genesis. Minerals of platinum group II – Pt > Ir type are fluid-metamorfic genesis. II - Pt> Ir, I - Pt and I - Pt> Os types are complicated hydrothermal-metacomatic by association minerals of platinum group (III) connected with process serpentinization the ultrabasic rocks. Formation of chromite schlieres with minerals of platinum group II – Pt > Ir type inclusions probably are result of high-temperature synmagmatic recrystallization of dunites. During this recrystallization processes the ore components (magmatic-chromespinelides and minerals of platinum group of the I - Pt and I – Pt > Os types) were extracted from the dunite plutonic complexes and concentrated in ore minerals of platinum group II – Pt > Ir type and chromite schlieres in the recrystallization-dunites (the texture varies from polygonal equigranular to porphyroclastic with fine-grained matrix).
