| Brekkebekkdalen-Straumsåsen-Styggberget-Fåset-Fåsteen zone This is a very well known zone consisting of separate occurrences of the Otta serpentine conglomerate and fragments of its ophiolitic substrate (Fig 37). At Brekkebekkdalen, or Steivanglia, the conglomerate forms a c. 200 m long N-S trending ridge in the terrain and with a width of at least 25 m (Helland 1893, p.116), (Braseth 1995, p.155). The northern part is non-talcified serpentinite conglomerate, whereas the southern part is strongly altered to soapstone, and with a very sharp E-W running border between the two (Olerud 1993, p.14). The soapstone has been exploited for more than a century and used both in dimension stone production, mainly for the typical "Østerdals" fire place, and production of small blocks (60 kg) for use in soda melting at the Moss cellulose factory (Braseth 1995, p.155-157). According to Olerud (1993) the soapstone is unsuitable as raw material for talc production due to the dark colour. From Karlsen and Nilsson 1999. |

| 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. |
