Polychronous evolution of neoarchean banded iron formation in the main ore sequence of the Kostomuksha greenstone belt: the age of zircons and accessory minerals // Transactions of Karelian Research Centre of Russian Academy of Science.

The banded iron formation (BIF) of the Neoarchean (2.76-2.74 Ga) Kostomuksha Formation of the Kostomuksha greenstone belt of the Karelian Craton was shown to contain the following accessory minerals: zircon, apatite, monazite and barite. Zircons from BIF have 2.9-2.8 Ga magmatic cores indicating the presence of Mesoarchean rocks in source areas. Metamorphic zircons were dated at 2.73, 2.64 and 1.86 Ga. They mark the polymetamorphic evolution.
