Abstract

Forkortet: The author gives some observations made on a tour along the shores of the Balsfiord, which goes inland from Tromsø; the occurrence of the rock described by Rosenbusch as sagvandite, a mixture of enstatite and magnesite. P. 127,128 are shown a sketch and a map of the easternmost of the two hills in which the sagvandite occurs. The surrounding rock is gneiss and finegrained crystalline schists allied to it; the stratification of surrounding rocks near the sagvandite is everywhere seem to have the same strike as the sagvandite. The author finally mentions the raised beaches of the Balsfiord.
