Data on REE chemistry of the Ordovician basaltic volcanites of Smøla show marked LREE enrichment and patterns which correspond with those known from Pleistocene and Recent calc-alkaline Javas of intraoceanic setting. This confirms earlier work suggesting that eruption of the Smøla volcanic rocks occurred
in a mature, evolved, island are environment. Comparison with data from the broadly coeval, calcalkaline, lower part of the Snåsavatn volcanites 250 km to the northeast suggests that the latter were erupted doser to the palaeo-continental margin than was the case for the Smøla rocks.
