Book Description
"This Special Paper presents a collection of 19 papers contributed to a joint Field Forum organized by the Geological Society of America and the Geological Society of South Africa in July 2004 in the Barberton Greenstone Belt and the Vredefort Dome, South Africa. The papers cover a wide variety of themes, including Archean and Proterozoic crust formation and geodynamics (with an appraisal of evidence of Archean subduction processes); the significance of impacts in the evolution of the early Earth's crust; traces of early life in Archean environments of Australia and South Africa and related studies of depositional environments; and processes affecting the giant Witwatersrand gold deposit."--Publisher's website.

Book Description
This book provides a comprehensive overview of the evolution of one of the oldest and best-exposed Archaean cratons on this planet. There is currently a renewed interest in the early Earth, and the Kaapvaal craton has long served as a model for early crustal evolution. This unique multidisciplinary resource features information on geology, tectonics, geochemistry, and geochronology. It offers a wealth of new data on various aspects of the craton as well as contributions on the various crustal units by international specialists.

Book Description
(Cont.) Lower crustal thermochronology also reveals the influence of a thermal perturbation to the southern African lithosphere in the Late Mesozoic, consistent with a broad upper mantle thermal anomaly associated with southern Gondwana breakup. The patterns of lower crustal heating are spatially and temporally complex, suggesting the importance of pre-existing lithospheric structure as a control on advective focussing. U-Pb zircon geochronology of basement lithologies from the western Kimberley domain of the Kaapvaal craton constrain a model for Neoarchean accretion of the Kimberley block to the eastern Kaapvaal shield at 2.9 Ga. The timing of this convergence through subduction beneath the western domain is correlated with a variety of Re-Os model ages for the underlying lithospheric mantle of the western craton, including peridotite depletion ages, eclogite formation ages and sulfide diamond inclusion ages, and suggests significant coupling of continental crust and lithospheric mantle formation and modification during convergent margin processes.
