IV. Litt om Jutulhugget
(NGU (79), Journal article, 1917)The Jutulhug (\"The big Troll's Notch\") is a cleft or canyon situated in the central part of Southern Norway under 62 degrees N. As our somewhat schematic drawing on p. 4 shows, it is situated in a wide saddle between the ... -
Age of the Krossnes Granite, West Norway
(NGU Bulletin (413), Journal article, 1988)Rb-Sr isotope whole-rock dating of the Krossnes Granite has yielded an isochron age of 430 \u00B1 6 Ma with I.R. = 0.07066 \u00B1 0.0005, interpreted as the age of intrusion. This age is close to that of the Håkre Granite ... -
