The Belomorian Province (also known as Belomorian Terrane, Belomorian Domain, Belomorian orogen, and Belomorides) is an area of the Fennoscandian Shield spanning the parts of the Republic of Karelia and Murmansk Oblast in Northwest Russia. The province is named after the Russian name for the White Sea.Sorjonen-Ward & Luukkonen 2005, p. 22. The main rock types are orthogneiss (derived from the tonalite-trondhjemite-granodiorite association), greenstone and paragneiss.{{cite journal |last1=Hölttä |first1=Pentti |last2=Balagansky |first2=Victor|last3=Garde |first3=Adam A.|last4=Mertanen |first4=Satu|last5=Peltonen |first5=Petri|last6=Slabunov |first6=Alexander|last7=Sorjonen-Ward |first7=Peter|last8=Whitehouse |first8=Martin |date=2008 |title=Archean of Greenland and Fennoscandia |journal=Episodes |volume=31 |issue=1 |pages=13–19 |doi=10.18814/epiiugs/2008/v31i1/003 |doi-access=free }} Although these rocks formed in the Mesoarchean and Neoarchean, they were disturbed by tectonic movements and heat 1900–1800 million years ago in the Paleoproterozoic. Located between the Kola and Karelian domains the collision of these two blocks would have caused the disturbance.Sorjonen-Ward & Luukkonen 2005, p. 24. According to one view the Belomorian Province could just be a more metamorphosed part of the Karelian Province to the west.
