The Akanvaara and Koitelainen intrusions, ca 2440 Ma old, represent a
group of cratonic mafic layered intrusions (aged from 2500 to 2440 Ma) of
the Fennoscandian (Baltic) Shield. These intrusions, which show all the standard
types of igneous layering, host deposits of chromite, vanadium, titanium,
platinum-group elements (PGE) and gold.
