Heltzén (1996) viser til at de eldste sporene av drift på kalkstein finnes ved Magerholm og det var drift her med kalkbrenning i 1860-årene. Bugge (1905) beskriver Magerholm som fortsettelsen av sonen fra Blindheim via Ekorn og Emblem. Kalkspatmarmoren varierer fin- til grovkornig, og har både tydelige forurensninger av grafitt, kvarts og andre silikatmineraler.

Abstract:
Forkortet: In the present paper it is shown, that the Romsdalen, in the Northwestern part of Norway in the Algonkian Formation, there occur some extensive beds of lime- stone which are more fit for the carbide- and sulphite-industry than those of the Oslo region. Limestone also occurs in the environs of Trondheim and in the Northern part of Norway here occurring together with some dolomites and they commonly show rather a high percentage of magnesia. Limestones also occur in the Southern and the Western part of Norway ( Kristiansand-Stavanger-Bergen). The author has made 8 analyses of limestone from Romsdalen (p.8). Besides on pp. 10 and 11 there will be found analyses from the Oslo region, on p.13 from Northern Norway and on p.14 from the environs of Trondheim. In Romsdalen the limestone contains the following minerals: quartz, scapolite, white mica, oligoclase, apatite, pyrite, graphite, garnet, pyroxene, amphibole, biotite and occasionally a green mica. The structure of these Algonkian limestones ahow partly those features which are common with contact-metamorphic marble, partly those which are common with regional-metamorphic marble, and they are therefore likely to possess an intermediate character.
