dc.description.abstract	The Eidfjord Granite has a 7-point whole-rock Rb-Sr isochron age of 931 +- 35 Ma with initual 87Sr\/86Sr = 0.7058 +- 0.0028 (50.0 X (10)9 year 87Rb half life; errors at 95 per cent confidence level). Two separated biotites show the imprint of Caledonian metamorphism and post-orogenic cooling: Rb-Sr age 393 +- 7 Ma; K-Ar ages 405 +- 10 Ma and 432 +- 10 Ma, respectively.
