Greenstone belts are zones of variably metamorphosed mafic to ultramafic volcanic sequences with associated sedimentary rocks that occur Precambrian Geology Archaean and Proterozoic cratons between granite and gneiss bodies.
The name comes from the green hue imparted by the colour of the metamorphic minerals within the mafic rocks: the typical green minerals are chlorite, actinolite, and other green.

PRECAMBRIAN GEOLOGY OF BAIRD TOWNSHIP INTRODUCTION Baird Township is located in the Red Lake greenstone belt and includes the towns of Madsen and Starratt-Olsen.
The east boundary of the township is 5 km west of the town of Red Lake. The township is bordered by Killala, Fairlie and Heyson townships on the west. The Precambrian rocks, older than 2, m.y., in the Saganaga Lake-Northern Light Lake area on the Minnesota-Ontario boundary include a thick succession of metavolcanic rocks, chiefly greenstone but with some intermediate to silicic types, and minor metasediments; the Northern Light Gneiss; the Saganaga Muskego Township alkalic syenodiorite and granodiorite; and the Knife Lake Group.

Bornhorst, Rodney C. Johnson, Rodney C. Johnson, P. Sims, L.M.H. Carter. The Abitibi Greenstone Belt (AGB), and specifically the Blake River Group, affords us the relatively rare opportunity to study seafloor volcanic and hydrothermal processes in an area that is both accessible and has a significant thickness of exposed extrusive pile.
We plan to study mafic volcanic rocks of the AGB that were erupted as part of an ancient Archean seafloor sequence. Our proposed. The trondhjemitic Northern Light Gneiss, Saganaga Tonalite, and syenodioritic to granodioritic Icarus pluton are part of a typical Archean igneous sequence that began with the extrusion of large volumes of basic volcanics, which make up large parts of present-day greenstone belts, and ended with a small post-kine-matic alkalic stock.
