Extending A Continent: Architecture, Rheology And Heat Budget (geological Society Special Publications)

Over the last three decades, there has been a growing appreciation of the role of extensional tectonics in convergent orogens. The opening contribution, by Brian Wernicke, provides a flavour of how this detachment era has changed our views on tectonometamorphic relationships in mountain belts. It gives a historic view of how our ideas about large-scale tectonic contacts in mountain belts have changed over the years. Wernicke concludes that controversy still persists over the existence and mechanics of slip on shallowly dipping extensional detachments. However, incontrovertible field evidence shows that slip on shallowly dipping extensional faults occurs in nature. The other papers provide a mix of new, innovative and controversial ideas that may help to solve the mechanical paradox on slip on shallowly dipping extensional detachments and quantitative case studies from New Zealand, the Aegean extensional province, the Alps and Finland.

They provide an important constraint on the initiation of horizontal motion of lithospheric plates on Earth and have been responsible for major growth of the continental lithosphere through the addition of juvenile magma. SP312 South Caspian to Central Iran Basins Edited by M F Brunet, M Wilmsen and J W Granath ISBN: 978-1-86239-271-7 Publication Date: May 2009 Pages: 360 Hardback Prices: $190 The data and models in this volume present a comprehensive picture of the Late Palaeozoic to Cenozoic evolution of the South Caspian to Central Iran region. Geodynamic processes and basin evolution are mainly controlled by the successive closure of the Palaeo- and Neo-Tethys oceans and the associated collisions, interspersed with periods of extension. SP291 The Geodynamics of the Aegean and Anatolia Edited by T Taymaz, Y Ylmaz and Y Dilek ISBN: 978-1-86239-239-7 Publication Date: December 2007 Pages: 320 Hardback Prices: $190 The Aegean region is considered to be a perfect natural laboratory in which to study the mechanisms of core complex formation, synchronous basin evolution and subsequent graben formation in late orogenic continental extensional deformation following crustal thickening due to orogenic contraction. The region has been the subject of intensive research for several decades. This will be essential reading about the structural evolution of the Eastern Mediterranean.

They can be broken into retreating and advancing types, based on their kinematic framework and resulting geological character. This volume presents fourteen papers dealing with general aspects of accretion and metamorphism and discuss examples of accretionary orogens and crustal growth through Earth history, from the Archaean to the Cenozoic

in Controlling Continental Break-up, Extensional Tectonics Is One Of The Most Fundamental Processes That Shape The Face Of Our Planet. Extension And Break-up Is Key To Understanding The Evolution Of Continents, And The Origin Of Sedimentary Basins And Their Hydrocarbon Potential, As Well As The Thermo-haline Circulation In The Oceans And Thus Global Climate.
