Cooling history of the eastern Svecokarelides: whole-rock and mica Rb-Sr and hornblende K-Ar ages in the areas of Pihtipudas-Iisalmi and Joroinen-Sulkava, Finland
Rb-Sr age determination on mica and whole-rock samples and K-Ar age determination on hornblendes were carried out to get information on the time of metamorphism and early cooling in two Proterozic areas of the Finnish Svecokarelides. In the Joroinen-Sulkava area (southern Finland) a whole-rock isoch...
