The gold and platinoid resources of the Karelian region are expected to increase. Our prediction is based on the leading genetic types of noble-metal mineralization known in the region such as the low-sulphide Pt-Pd type in layered plutons and gabbro-dolerites, CuU-Mo-V-Pt-Pd-Au polygenic Padma type, orogenic mesothermal gold type and complex gold-porphyry type, as well as new types not reported earlier such as stratiform black shale type, iron oxide type with copper and gold (IOCG) and Rompas gold-uranium type. Noble-metal mineralization in the metapyroxenites of the Kaalamo and Välimäki igneous complexes, Latvasyrja aposkarn metasomatic rocks in Priladozhye (Lake Ladoga area) and Zaonezhye (Trans-Onega) black shales are described briefly mineralogically and geochemically. The mineralogical and geochemical indicators of noble-metal ore formation in Karelia’s Paleoproterozoic trapps, tested at the Pudozhgorsky igneous complex and the Chinozero sill, are identified. Variations in the PT-parameters of ore formation in the Koikary-Vygozero shear zone are interpreted as a reliable criterion for its predictive metallogeny evaluation for orogenic gold.
