Selbu. Fjeldbygningen inden rektangelkartet Selbus omraade

Abstract

Forkortet: The present paper is a description published together with the geological map of Selbu, the country around the Selbu lake, SE of Trondheim. The Trondheim district has already been geologically mapped on a smaller scale and described by Kjerulf; several of the maps on the 1\/100 000 scale have also been published. The literature in which may be found special reference to Selbu and the evidence upon which Kjerulf bases his stratigraphical divisions of the Trondheim district is cited p. 5-6. A map showing the routes of the geological surveyors in Selbu is given p.7. It must be noticed that notwithstanding the work done, the stratigraphical divisions in the Trondheim district cannot yet be looked upon as definetely fixed. Fossils are, as will be seen from the literature cited, few and far between; the various regional metamorphoses extending over large tracts of country seem to have effectually destroyed most of the vertiges of organic life. Within the precincts of the Selbu map no fossils have as yet been discovered; the nearest place where any have been found is in Holtålen, S of Selbu: here Professor Vogt in 1888 found dictyograptus. Kapittel s. 29-36: Kvernstensdriften i Selbu.
