Greenstone Belts


Book Description

This book is the first comprehensive compilation of data and ideas relating to the origin, evolution, and significance of the world's greenstone belts, and includes contributions from over 100 experts. In the first of two parts, reviews are presented on broad topics relating to the geology of greenstone belts and their surroundings, covering mainly post-1980 research. These include: historical, sedimentologic, volcanic, structural, metamorphic, metallogenic, and thermal aspects; summaries of mafic/ultramafic magnetism, strain, fluids, geophysics and deep structures; relations with associated granitoids, tectonic evolution, and geochronology; and field relationships. The second part takes a more focused look at the geology of specific cratons and individual greenstone belts worldwide, including Archaean, Proterozoic, and Phanerozoic examples. Detailed geologic maps on large and small scales, extensive tabulations of data, and short written summaries of the salient features are included for all belts. The book will be a valuable reference tool for academic and industrial researchers, students, explorationists, and anyone interested in the evolution of Earth processes over geologic time.

The Geology of the Belingwe Greenstone Belt, Zimbabwe


Book Description

A study on the Bellingwe Greenstone Belt, presenting the stratigraphy of the belt, its structure and tectonic setting, the sedimentology of what may be a rift basin, the geochemistry of the freshest Archaean komatiites yet found, and models of the evolution of the region.

Archean Base and Precious Metal Deposits, Southern Abitibi Greenstone Belt, Canada


Book Description

The Abitibi greenstone belt of eastern Canada represents the world's largest Neoarchean terrane of supracrustal rocks. Straddling the border between the provinces of Ontario and Quebec, the belt covers an area that is approximately 700 km from southeast to northwest and 350 km from north to south. The belt is comprised of several major east-trending successions of folded volcanic and sedimentary rocks, with intervening intrusions. The supracrustal rocks of the Abitibi greenstone belt are uniquely well preserved and have mostly been overprinted only at a low metamorphic grade, allowing the study of primary geological relationships.




Encyclopedia of Earth and Space Science


Book Description

Provides a comprehensive reference for Earth and space sciences, including entries on climate change, stellar evolution, tsunamis, renewable energy options, and mass wasting.




Precambrian Geology and Metamorphic Petrology


Book Description

The proceedings of the 30th International Geological Congress held in Beijing, China in August 1997. This volume focuses on Precambrian geology and metamorphic petrology. It aims to present a view of contemporary geology to researchers interested in the geological sciences.




Cratons and Fold Belts of India


Book Description

Cratons and Fold Belts of India, is a unique attempt at presenting geological characteristics and evolution of the fold belts and the cratonic areas of the Indian shield. The author has evaluated the different evolutionary models for each fold belt in light of all the currently available geological and geochronological informations that are clearly listed. Shortcomings, if any, of each model are stated and a viable geodynamic model is presented for each fold belt. The book is self-contained – it includes an introduction to the processes of mountain building, especially plate tectonics theory with its application to the evolution of the Himalaya as an illustrative example – so that the reader can better appreciate the novel approach to the evolution of Proterozoic fold belts. The author eschews a detailed account of the fold belts for a clear description of all the concepts that go into building models. It is primarily written for graduate students, teachers and for those geoscientists who aspire to know all about the Indian shield.
