Available lithostratigraphic, tectonothermal, geochronological and paleomagnetic data from
2.1–1.8 Ga collisional orogens and related cratonic blocks around the world have …

Geological and paleomagnetic data support the hypothesis that a Paleo-Mesoproterozoic
supercontinent, referred to as Columbia, existed before the formation of Rodinia. This pre …

Trace element concentrations and combined Sr-and Nd-isotope compositions were
determined on stromatolitic carbonates (microbialites) from the 2.52 Ga Campbellrand …

A combined solution for the two major terrestrial lead paradoxes has been sought. These
are the 'future'paradox (upper crustal and upper mantle Pb isotope compositions plot in the …

An outstanding feature of the Archaean Eon is that it was a time of major production and
preservation of continental lithosphere. Here I review the geological, geochemical and basic …

Abstract U–Pb and Lu–Hf isotope analyses, obtained by laser ablation-sector field-
inductively coupled plasma-mass spectrometry on zircon grains from 37 granitoid samples …

Modern-style plate tectonics can be tracked into the geologic past with petrotectonic
assemblages and other plate-tectonic indicators. These indicators suggest that modern plate …

A combined set of U–Pb and Lu–Hf in sit u laser ablation ICP-(MC)-MS zircon analyses were
obtained from orthogneisses and granitoids in the Central Zone of the Limpopo Belt, which …

The Precambrian foundation of southern Africa consists of Archaean cratonic nuclei
surrounded by belts formed during three separate Proterozoic orogenic episodes. Crust that …
