| Abstract: | Based upon the composition of carbonatites of the Fen Complex in Norway and the Alnö Complex in Sweden, the following nomenclature of carbonatitic rocks is suggested: Carbonatites (> 70 % carbonate minerals), sub-divided into the calcitic sövites and alvikites, the dolomitic to ankeritic rauhaugites and beforsites and the alkali-carbonatitic lengaite. Silico-carbonatites are rocks with 50–70 % carbonate minerals. They are subdivided into silico-sövites, silico-alvikites, silico-rauhaugite and silico-beforsite. |
