The marble layer which is a potential resource is unusually coarse-grained. It is white and with grains of calcareous spar of up to 1 cm, usually ½ cm, and visually has none or a very small one proportion of other minerals, only around 1%. It is identified very small grains of graphite, quartz and light mica (muscovite) in the marble between the large grains of lime spar. Compared to others marble deposits in Nordland the marble is very little contaminated by other minerals.
