Komatiites and komatiitic basalts within the Neo-Mesoarchaean, ca. 2.8 Ga greenstone belts in the western part of the Karelian craton in Finland formed in diverse palaeoenvironments. The lavas in the Tipasjärvi and Kuhmo greenstone belts formed in an oceanic plateau environment, whereas the komatiit...
