Late Proterozoic — Early Paleozoic granitoids in the northern part of the Kolyma tectonic block are A-type granites. They formed in an intraplate setting. They have chemical affinities with ultrametamorphic granites and rapakivi, and have potential for rare elements and gold mineralization. The granitoids crystallized under conditions of high oxygen and volatile fugacities, which is favourable for mineralization.
