Description
Small pit in soapstone. According to Wennberg (1959) the deposit, which occurs within a gabbro, can be traced more than 200 m. The width is 20-30 m. The pit seems to have a length around 30 - 40 m and a width around 20 m. The soapstone is fine-grained and apparently of rather good quality. It contains much talc and little magnesite, but is rich in pyrite and contains some chlorite (Karlsen et al. 1999a). The deposit has been investigated by drilling by NGU (Lund 1986a, 1986b). It is possible that the deposit has been protected because of the existence of heritage relicts. From Karlsen and Nilsson 1999..

Talc deposits in Norway
;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.99.135;146 pages
Abstract:
Information about talc and soapstone deposits registered in NGU's different databases and various available literature have been collected and described in the present report. Around 400 deposits/occurrences are known, but the detail of the available information varies widely. By reading old field-books as well as old manuscripts, maps, etc. dating as far back as A.D.1758, quite a lot of data has been found. The result of the work shows that most described talc in Norway is of ultramafic origin and is associated with serpentinites. The most common mineral association is talc + breunnerite. Different talc-provinces can be defined from the registered and non-registered data, the most important being Nord-Gudbrandsdalen, Altermark and Stølsheimen. While Altermark and Stølsheimen have been investgated in some detail with respect to talc as an industrial mineral, the Nord-Gudbrandsdalen talc province has been investigated both for milling talc and for soapstone use as dimension stone. Deposits that are probably extensive, but have so far not been investigated in detail, include the Lesjehorrungane deposits in the Nord-Gudbrandsdalen region and the Raudfjellet deposit in Nord-Trøndelag. The fractionated metakomatiites (pale green talc-chlorite rocks) of the southern part of the Palaeo-proterozoic Karasjok Greenstone Belt in Finnmark, Northern Norway, possibly represents, by far, the largest accumulations of talc in Norway. These rocks are recently mapped, for the first time, but other critical information is, however, very scarce.

Rapport om en befaring av klebersteinsforekomster i Skjerstad og Fauske herreder.
;Norges geologiske undersøkelse;FAGRAPPORT;Bergarkivet; No.BA 7462;2 pages
Abstract:
3 klebersteinsforekomster i Skjerstad er befart sammen med bl.a. en repre- sentant for Domkirka. 1. Klette (=Vargåsmyran?): ujevn kvalitet med mange stikk omvandlet olivin- gabbro. Ligger 2-3 km N for Misvær kapell. 2. Høgset: ukjent beliggenhet i 1992. Ujevn kvalitet m/asbest og tremulitt. 3. Stolpe: N for gården Stolpe i Misværdalen. Bra kvalitet med lite stikk, noe kis og smale kvartsårer. Kleberstein ligger i gabbro og kan følges over 200 m, bredden er 20-30 m. Fortjener oppmerksomhet. I tillegg nevnes Djuposen i Valnesfjord som en forekomst i klasse med Stolpe.

Sonderende undersøkelse av kleberstensforekomster ved Misvær og Stolpelia.
;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.85.204
Abstract:
En befaring/kartlegging av kleberstenspotensialet i Skjerstad kommune viser flere sonerte peridotittkopper med stedvis klebermineralisering. Overdekningsgraden er ganske betydelig. Det foreslås derfor at utvalgte områder må detaljkartlegges og at forekomsten ved Stolpelia oppbores.

Diamantboring av klebersteinforekomster ved Stolpelia.
;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.86.229 / 86.299
Abstract:
Oppboring av Stolpelia klebersteinsforekomst har påvist en tonnasje i størrelsesorden 37.000 tonn kleber med tildels betydelig bedre kvalitet enn det som tidligere er tatt ut. (Rapporten feilmerket 86.299)
