K-Ar age determinations of the Alta-Kvænangen window rocks, northern Norway
K-Ar age determinations have heen made on ophiolitic material from the Alta-Kvænangen window. Isotopic dilution was also necessary for the potassium measurements. Minimum ages of 1.4 to 1.5 b.y. have been found. These ophiolites have thus a Precambrian age. A formation age of 1.8 to 2.0 b.y. is also...
