The Belomorian Province (also known as Belomorian Terrane and Belomorian Domain) is an area of the Fennoscandian Shield spanning the parts of the Republic of Karelia and Murmansk Oblast in Russia. The province is named after the russian name of the White Sea.[1] The main rock types are orthogneiss (derived from the Tonalite-Trondhjemite-Granodiorite association), greenstone and paragneiss.[2] Although these rocks formed in the Mesoarchean and Neoarchean,[2] they were disturbed by tectonic movements and heat 1900–1800 million years ago in the Paleoproterozoic.[1] Located between the Kola and Karelian domains the collision of these two blocks would have caused the disturbance.[1][3] According to one view the Belomorian Province could just be a more metamorphosed part of the Karelian Province to the west.[3]
