I. L.: kommentar: Forekomsten er en av flere pegmatitter knyttet til Råna intrusjonen. Forekomstene var hovedsakelig utnyttet pga. glimmer, mest før og under siste verdenskrig. Spørsmålet er om pegmatittene kan være aktuell som råstoff for superren kvarts? Har de spesielle mineraler som gjør dem interessante? Forekomstene av denne typen bør ses på under ett. Også denne forekomsten som Kaldådalen ligger relativt nært Nikkel og Olivin AS anlegg men svært høyt til fjells. Konklusjon: Forekomsten er en liten linse hvor kvarts-feltspat-muskovitt er intenst sammenvokst. Muskovitten har vært utnyttet. Sannsylig svært lite interessant. Litteratur: Poulsen, A.

Abstract:

The situation of the map Tysfjord is shown on p. 10. It comprises a very rugged country between the coast and the frontier, with several glaciers and mountains up to 1744 meter. The present paper contains the geomorphology, general geology, tectonics and glacial geology of the district, further the history of mining, a full description of all the non-metallic mineral deposits and of those ore deposits, which are restricted to this map area. The petrology and the rock analyses (amounting to more than 30) are reserved however for a special paper dealing with a wider district. The same is the case with the main ore deposits in the northern part, extending outside the map area. A main feature of the geomorphology of the district is the extreme westerly position of the main Scandinavian watershed. Its distance from the head of some of the present fjords is only 3 km, and in late glacial time this distance in one place was only 1 km. From here the water runs 350 km eastwards to the Gulf of Bothnia. There is scarcely to be found a parallel elsewhere to such an extreme position. The sceneries on both sides of this watershed are widely different.
