Abitibi greenstone belt - Wikipedia
The Abitibi greenstone belt is one of the world's largest Archean greenstone belts. It represents a series of subterranes that exhibit similar geological, geochemical, and isotopical signatures similar to those formed during the evolution of paired active-arc-back-arc systems.
Geology of the Abitibi Greenstone Belt - GeoScienceWorld
The Abitibi greenstone belt, which straddles the border between Ontario and Quebec in eastern Canada, represents one of the largest and best-preserved Neoarchean greenstone belts in the world. The belt consists of E-trending successions of folded volcanic and sedimentary rocks and intervening domes of intrusive rocks.
The World-Class Abitibi Greenstone Belt of Canada
2013年7月16日 · The AGB is a 150 km wide greenstone belt that stretches for 650 km across Eastern Canada, from Wawa, Ontario in the west to Val d’Or, Quebec in the east. The area has produced over 180,000,000 ounces of gold and more than 450,000,000 tons of Cu-Zn ore since the early 1900’s.

We describe major revisions to stratigraphy of the Abitibi greenstone belt and the implications of an autochthonous development of the vol-canic stratigraphy for exploration for syngenetic mineralization.
Metallogeny of the Abitibi Greenstone Belt, Canada
2023年12月26日 · The Abitibi greenstone belt, extending from northeastern Ontario to northwestern Quebec in Eastern Canada, is the largest belt of Neoarchean supracrustal rocks on the planet, and also one of the richest in terms of base and precious metals, including several critical and strategic metals.
Formation of the Abitibi greenstone belt by arc-trench migration
1995年5月1日 · The Abitibi Greenstone Belt (AGB) is the largest and the best-preserved greenstone belt of Archean age in the world. It consists of both mafic and felsic rocks with ages ranging ≈2730-2680 Ma...
This review focuses on the Abitibi greenstone belt because it is a gold-endowed belt that contains several Au and Cu-Au porphyry deposits formed during the ~100 My magmatic phase that ends at ca. 2.70 Ga (see below) prior to the main deformation phase.
