dc.description.abstract	Rb-Sr isotope whole-rock dating of undeformed and unaltered parts of the Blåfjellhatten granite has yielded an isochron age of 1356 +- 29 Ma with I.R.=0.7254 +-0.0027, interpreted as the age of intrusion. This age contrasts with an earlier interpretation of the granite as part of the 1780-1650 Ma Transscandinavian Granite-Porphyry Belt and with other dates from the Grong-Olden Culmination and other basement windows in the central Norwegian Caledonides. The new data indicate that the Blåfjellhatten granite is not directly related to any of the major tectonothermal events of the Baltic Shield.
