Rapakivi-gesteenten uit het Oslogebied
Grondboor & Hamer , Volume 23 - Issue 3 p. 109- 117
Until now in the counting of erratics many Norwegian rock types have been overlooked, because they are not recognized. It was found possible, however, to collect about 1100 erratics from the Oslo region in the NW part of Germany and the NE part of the Netherlands, during a period of 10 years. The collection consists of about 60 different igneous rock types, but the number of transitions and varieties is far greater. A description of six new indicator rocks from the Oslo region is given, among them is Drammen-rapakivi. Reeds verschenen publikaties over Miste.
