The Gullsteinberget and Knøsberget kyanite quartzite deposits

Abstract

Confidential until 01.01.2009The kyanite quartzite occurrences of Gullsteinberget and Knøsberget in Solør were mapped, sampled and analysed in order to determine the quality and distribution of potential quartz raw material. From the field mapping three potential bodies could be identified: (1) a 50 x 20 m, NE-SW striking body ca. 100 m ESE of the Gullsteinberget top, (2) a 50 x 40 m, NE-SW striking kyanite quartzite lens in the central part of the Gullsteinberget West target area and (3) a 50 x 10 m, NE-SW striking lens at Knøsberget. The average grain size of quartz is 0.5 to 1.3 mm at Gullsteinberget East (body 1), 0.5 - 1.0 mm at Gullsteinberget West (body 2) and 0.2 to 0.4 mm at Knøsberget (body 3). On the basis of these field observations a 400-kg sample were taken from body 2 for a processing test.
