Norwegian Minerals and Rocks of Possible Caledonian Origin


IN a recent communication1 an outline is given of the sequence of metamorphic and structural events which affected the Lewisian rocks of the Glenelg inlier. In this outline a period of folding, about 740 million years old, and certainly older than 560 million years, is considered to form part of the Caledonian orogeny. Further can be mentioned the intrusion of the Ben Vuroch granite into Dalradian sediments between 700 and 500 million years ago2.
