The end of the Archean aeon (3.0–2.5 Ga) was a period of fundamental change in many
aspects of the geological record. In Archean cratons, this timespan is marked by a …

Abstract The Superior Province consists of northern and southern high-grade gneiss
subprovinces and a central region of alternating granite-greenstone and metasedimentary …

Archean sandstone and shale samples from turbiditic (TF) and alluvial facies (AF) in the
Southern Volcanic Zone of the Abitibi greenstone belt, Canada, have been analyzed for …

We have compiled a record of the geochronology of mantle plume activity between 3.8 and
1.6 Ga. Over this time period, the ages of komatiites, and those of global plumes, correlate …

The granite-and-greenstone terrains that dominate upper crust formed from about 3.6 to
about 2.6 Ga, and record magmatic and tectonic processes very different from those of a …

New mapping and U–Pb zircon geochronological results in the southern Abitibi greenstone
belt (SAGB) support an autochthonous regional stratigraphy comprised of nine supracrustal …

his book is intended for graduate students of the Earth Sciences who require a T
comprehensive examination of the origins of igneous rocks as recorded by the isotope …

Abstract Models of greenstone belt development are crucial for exploration. Allochthonous
models predict belts to be a collage of unrelated fragments, whereas autochthonous models …

Abstract Late Archean (ca. 2.7 Ga) lode gold mineralization in the Superior Province of
Canada and Yilgarn Craton of Australia was late kinematic, and syn to late peak …

Abstract We report precise 207 Pb 206 Pb single zircon evaporation ages for low-grade
felsic metavolcanic rocks within the Onverwacht and Fig Tree Groups of the Barberton …
