The chemical, mineralogical and structural properties of the Eocambrian limestone at Norra Hede in the province of Härjedalen have been investigated. This limestone has a small content of carbon and bituminous matter. The proportions of Ca : Mg in the carbonaceous cement are 5,77 : 1. The content of arenaceous matter is relatively great, consisting partly of drifted material. The limestone is laminated with alternating light and dark layers. There are also structures emanating from slumping and flow casts.
