According to Mortenson (1945) the location is in the hills which can be reached by following a 4 km long road from Søredalen. This is a rare type of occurrence for Norway as talc/soapstone here is formed by metasomatism of dolomitic calcite marble. The deposit and its mode of occurrence is described in detail by (Mortensen 1945). According to Dahl (1981) there has here been production during shorter periods covering a time span of several centuries, - more recent ones around 1900 and in the 1930s. All together c. 500 m³ rock has been quarried, most of which has been used as "talc" of various qualities. The talc occurs as pure, pale green and irregularly folded layers, interbedded with layers richer in chlorite or even chlorite and mica. The whole lensoid deposit is surrounded by granites. Remaining talc in the quarry is strongly cracked according to Dahl (1981). According to Mortensen (loc.cit.) minor layers or lenses of serpentine or talc occurs in the marble, but they have always shown to be small and little persistent. Mining has been concentrated basically on these minor accumulations of talc. Bugge (1929) reports up to 60 cm wide bands of light talc within a 5-6 m wide zone of chlorite schist within a 15x15 m cut in the quarry. Stone from this quarry is used on the façade of Stortingsgata 4 in Oslo (Capitol of Norway).
