Sammendrag
Forkortet: The Rennebu sheet embraces an area of about 590 square miles, situated about 28 miles south of Trondheim. Professor Tørnebohm (p.6) and Professor Kjerulf (p.6) have each given their view of the geological structure. The author's division is mentioned on p.9. It coincides in the main with Kjerulf's. First the Røros group is described, then the Hovind group. Above the Hovind group lie layers of breccia, the so-called breccia-slate (Brøgger), which consists of sometimes rounded fragments, and which the author supposes represents a disconcordance. Above these lies the Støren group, which consists of slates, sandstones, breccias, and variolitic diabase. The study of the geology of these regions was undertaken in 1903 by the geologist of Sverdrup's North Polar Expedition, P. Schei, but was interrupted by his sudden death. He had not published his views; but from a lecture that he delivered in the Norwegian Geological Society, it appeared that he compared these diabase with Scotch and English \"pillow lavas\". As such the author has here described them.
