E-Book Overview
The Palaeozoic geological history of western South America has been the focus of intense international interest in the last few years. This book brings together multidisciplinary research and review papers on the Lower Palaeozoic geology of the Sierras Pampeanas and the Precordillera of central west Argentina. It deals with the final stages of assembly of the supercontinent of Gondwana and a period of tectonic interaction with Laurentia (the North American continent of today). The evidence for the growth of this part of the margin of Gondwana from late Neoproterozoic times is presented in terms of stratigraphy, palaeontology, igneous petrology, geochemistry and geochronology, and rival tectonic hypothesis are critically compared. At least two episodes of subduction-related marginal basin closure and terrane accretion are documented and re-assessed.

It received its Royal Charter in 1825 for the purpose of 'investigating the mineral structure of the Earth'. The Society is Britain's national society for geology with a membership of around 8500. It has countrywide coverage and approximately 1500 members reside overseas. The Society is responsible for all aspects of the geological sciences including professional matters. The Society has its own publishing house, which produces the Society's international journals, books and maps, and which acts as the European distributor for publications of the American Association of Petroleum Geologists, SEPM and the Geological Society of America. Fellowship is open to those holding a recognized honours degree in geology or cognate subject and who have at least two years' relevant postgraduate experience, or who have not less than six years' relevant experience in geology or a cognate subject. A Fellow who has not less than five years' relevant postgraduate experience in the practice of geology may apply
