Iron ores associated with the ferrocarbonatites were worked in the eastern part of the Fen Complex between 1657 to 1927. A large number of iron mines, located in the Gruvåsen area near Ulefoss is worked in a carbonatite rock called rødberg ("red rock").
Hematite was mined from 1956 to 1925 with production estimated. at c. 10⁶ t (Bjørlykke & Svinndal 1960; Andersen 1983). The iron ores are typically lenses, veins and dike-like bodies within carbonatites and carbonated gneisses.
