Since the discovery of the first gold occurrences in the Chibougamau area in and in the Kirkland Lake, Timmins, and Rouyn-Noranda areas inthe Abitibi greenstone belt of eastern Canada has become one of the most explored and best studied Neoarchean volcanic and sedimentary terranes.

A geochronological, major/trace element geochemical and Nd–Pb isotopic study of early- to mid-Archean basement granitoids/gneisses, ∼ Ga greenstone belt and – Ga late-Archean granitoids from the Hanikahimajuk Lake area of the northern Slave province was undertaken to constrain the tectonomagmatic evolution of the north-central area of Slave province, Northwest Territories Cited by: Kresz, D.

Competing models on the origin and evolution of greenstone belts have important implications for the Archean Earth. The role of plate tectonics in the evolution of Phanerozoic and.

Granite-greenstone belts are one of the most important components of Archean cratons and record crucial information in the formation and evolution of early continental crust (Anhaeusser, Little is known about the Hadean and the Archean impact record on Earth.

In the CT3 drill core from the Fig Tree Group of the northern Barberton Greenstone Belt, 17 spherule layer intersections occur, which, provide an outstanding new opportunity to gain insights into meteorite bombardment of the early by: 4.

This is a minimum age for volcanism in the greenstone belt. A sample of gneiss from near the belt contains two populations of zircons with ages of ± 47 Ma and ± 9 Ma. The ca Ga zircons are interpreted as dating the formation of the granitic parent of the gneiss, and the ca Ga zircons are interpreted as dating gneiss Cited by:   The Abitibi belt in Canada is the largest Archaean greenstone ternane3, and has been a touchstone for many models because its surface geology is relatively well known8–10, it contains Cited by: Evolution of an Archean Greenstone Belt in the Stormy Lake-Kawashegamuk Lake Area (Stratigraphy, Structure and Geochemistry) - Western Wabigoon Subprovince, Northwest Ontario: Brock University: M.

Such orogeny can be accounted for if compressive deformation of the crust is accompanied by thinning of the mantle by: The Belingwe Greenstone Belt contains a variety of igneous and metamorphic rocks, set in a granite-gneiss terrain. Five main tectonic units are identified.

The oldest unit is the ~ Ga Shabani-Tokwe Gneiss Complex, forming much of the terrain to the east of the belt. The sediments in two of South Africa's major Archaean greenstone belts, the Barberton and Pietersburg greenstone belts, span an age range of some million years.

Both greenstone belts represent remnants of extensive fold and thrust belts with complex, but different polyphase tectonic histories.

The oldest sediments were deposited between circa and M.a. on oceanic like crust Cited by: The Red Lake greenstone belt is Archaean in age (older than billion years) and is located in the Superior province of the Canadian Precambrian Shield. It is a fairly typical greenstone belt, being composed of a complex assemblage of lavas, sediments, and by: 3.

Archean plate motions. geologists believed that during the Archean some type of what occured. plate tectonics. Archean plates are believed to have moved. Organic compounds of the kind required for the origin of early life readily dissolve in the warm waters of the mid-ocean ridge area, but these compounds are protected in that warm area by and Although the origin is unclear, most cratons of the world experienced major episodes of metamorphism between about __________ billion years ago.

Radiometric age determinations suggest that the major thermotectonic event responsible for the present distribution of rock types was the Liberian (c. Ma), though there is inconclusive evidence of earlier events. It is also possible that the Marampa and Kasila Groups may be younger than the bulk of the ‘typical’ greenstone : J.

Wright. ARCHAEAN granite–greenstone terrains such as the west African and Rhodesian Cratons, are frequently bordered by pene-contemporaneous, long-lived, high-grade mobile belts containing granulite Cited by: The project aim is to define conditions at the surface of the Archean Earth through detailed study of drill cores from the Barberton Greenstone Belt, South Africa.

The focus will be on the nature of the sedimentary and volcanic rocks that formed the habitat of early terrestrial life. The geochemistry and isotope systematics of Archean greenstone belts provide important constraints on the origin of the volcanic rocks and tectonic models for the evolution of Archean cratons.
