The 2,677 million year old Abitibi greenstone belt in Ontario and Quebec is one of the largest Archean greenstone belts on Earth and one of the youngest parts of the Superior craton which sequentially forms part of the Canadian Shield. [6] Ontario's metallic mineral wealth such as gold, copper and zinc comes from the Abitibi/Wawa subprovince. [5]
The Abitibi greenstone belt is a 2,800-to-2,600-million-year-old greenstone belt that spans across the Ontario–Quebec border in Canada. [1] It is mostly made of volcanic rocks , but also includes ultramafic rocks , mafic intrusions , granitoid rocks , and early and middle Precambrian sediments.
Around the world, greenstone belts are a hallmark of ancient Precambrian rocks. The Ennadai-Rankin greenstone belt is the second largest in Canada and displays felsic volcanic and volcaniclastic rocks, as well as mafic rocks reaching greenschist grade on the sequence of metamorphic facies.

The Nuvvuagittuq Greenstone Belt (NGB; Inuktitut: [nuv.vu.a.git.tuq]) is a sequence of metamorphosed mafic to ultramafic volcanic and associated sedimentary rocks (a greenstone belt) located on the eastern shore of Hudson Bay, 40 km southeast of Inukjuak, Quebec. These rocks have undergone extensive metamorphism, and represent some of the ...
