The Archaean-Proterozoic boundary beneath the Caledonides of northern Norway and Sweden: U-Pb, Rb-Sr, and isotope data from the Rombak-Tysfjord
The Baltic Shield includes an Archaean craton in northeastern Finland. Early Proterozoic accretions to this Archaean craton comprise of (1) the Svecofen- nian domain, which consists of island arc volcanic and sedimentary rocks that formed at 1.94 - 1.85 Ga and that between 1.83 and 1.78 Ga became in...
