Svekokarelian thrusting with thermal inversion in the Karasjok-Levajok area of the northern Baltic Shield
Krill, Allan G. (NGU Bulletin (403), Journal article, 1985)Recent mapping, isotopic dating, and metamorphic and structural observations from the Karasjok-Levajok are, lead to a tectonic interpretation that is similar in many ways to Phanerozoic plate tectonic models. Three major ...
