Lithogeochemical character of mafic and ultramafic plutonics in Northern Sweden

Abstract

Northern Sweden is dominated mainly by Paleoproterozoic rocks. Igneous activity during the Svecofennian orogeny (1.93-1.87 Ga) created vast amounts of both volcanic and plutonic rocks within and around the Archaean craton. Post-orogenic 1.80-1.77 Ga granitoids were formed later within the same region.
