Summary:Both Archaean and early Palaeoproterozoic rocks occur NW of the large 2440 m.y. Koitelainen layered mafic intrusion. Archaean rocks older than 3000 m.y. are exposed in the Tojottamanselkä dome, and zircons from a quartzofeldspathic gneiss within the Pomokaira basement complex give an age of 2486 ± 4 m.y., representing the Palaeoproterozoic cover of the basement.
