- Rapporter 
A number of carbonate occurrences in the Evenes and Rolla areas, in Nordland and Troms County respectively, contain calcium carbonate with low content of crystal-bound iron and manganese. The calcite in such rocks has potentially high whiteness, and the rock might be suitable for production of high-purity calcite products (such as GCC). Short core boreholes have been drilled to provide continuous samples from four localities in the Evenes area and five loalities at Rolla.
