Abstract
The first ever comprehensive geochemical data on the Kontay intrusion, polar Siberia, demonstrate that the intrusion is profoundly differentiated and shows geochemical features typical of intraplate magmatism. The age of the intrusion is Early Paleozoic. The paper summarizes literature data regarded as circumstantial evidence that a large magmatic intraplate (perhaps, plume-related) province of Early Paleozoic age may occur in the northern part of the Siberian Platform, whose only component found as of now is the Kontay intrusion. The intrusion is demonstrated not to possess any precious-metal (Ag–Pd) ore potential, contrary to what was surmised previously.
