special papers collisional delamination in new guinea the geotectonics of subducting slab breakoff by mark cloos benyamin sapiie andrew quarles van ufford richard j weiland paul q warren and timothy p mcmahon 2005 the island of new guinea is primarily the product of the most recent oceanic arc­continent collision on earth the mountainous spine the central range is a 1300-km-long by 100­150-km-wide belt with numerous peaks over 3 km elevation deformation that led to creation of the central range began when the australian passive margin entered a north-dipping subduction zone in the middle miocene collisional tectonism began at 8 ma and ended at about 4 ma with a change to strike-slip movements in the core of the range delamination of the lithospheric mantle underpinning caused asthenospheric upwelling and magma generation the shallow intrusion of felsic magmas generated copper and gold ore deposits the most spectacular of which are concentrated in the ertsberg mining district in the western central range regional relationships and fieldwork near the mining district along with geomechanical reasoning are the basis for making a detailed reconstruction of the events leading up to and during collisional orogenesis spe400 51 p isbn 0-8137-2400-7 $30.00 member price $21.00 special paper 399 wetlands through time edited by stephen f greb and william a dimichele 2006 the importance of wetlands in the global ecology is undisputed this is not only true of present wetlands but has been true of wetlands for at least the last 400 million years in fact with changing flora and fauna there has been an evolution of wetland functions and ecological links because many wetlands are located in lowland habitats and have poorly oxygenated substrates they have the potential for rapid burial with little erosion and high potential for preservation for these reasons abundant fossil flora and fauna have been found in association with ancient wetlands which are a cornerstone of the terrestrial fossil record and of our understanding of earth history likewise the coals we use as an energy resource are ancient wetland deposits wetlands through time contains 14 research papers on the ecology and importance of ancient wetlands spanning the time from the initial colonization of plants on land to an ice-age mammoth-bearing wetland spe399 304 p plus index isbn 0-8137-2399-x $80.00 member price $56.00 wetlands ds ds through time h time im ime me edited by stephen f greb and william a dimichele penrose conference series tectonics climate and landscape evolution edited by sean d willett niels hovius mark t brandon and donald m fisher 2006 this anthology covers a wide range of topics across the interface of tectonics climate surface processes and the evolution of the earth s topography arising from a penrose conference on the same topic the 26 papers in this book comprise a comprehensive snapshot of current research topics in this interesting field of cross-disciplinary research topics include the relationship between topography and precipitation modeling and field studies of the coupling between surface erosion and tectonics geochemical methods for measuring erosion rates and paleotopography and the use of digital topographic data to infer tectonic climatic or surface processes spe398 434 p plus index isbn 0-8137-2398-1 $95.00 member price $67.00 geoinformatics data to knowledge edited by a krishna sinha 2006 the science of informatics in the broadest sense has been several thousands of years in the making with the recent emergence of large storage devices and high-speed processing of data it has become possible to organize vast amounts of data as digital products with ontologic tags and concepts for smart queries coupling this computational capability with earth science data defines the emerging field of geoinformatics since the science of geology was established several centuries ago observations led to conclusions that were integrative in concept and clearly had profound implications for the birth of geology as disciplinary information about earth becomes more voluminous the use of geoinformatics will lead to integrative sciencebased discoveries of new knowledge about planetary systems twenty-one research papers co-authored by 96 researchers from both earth and computer sciences provide the first-ever organized presentation of the science of informatics as it relates to geology readers will readily recognize the vast intellectual content represented by these papers as they seek to address the core research goals of geoinformatics spe397 288 p isbn 0-8137-2397-3 $80.00 member price $56.00 blocs of docs view and download articles from gsa journals and individual chapters from gsa books 1997­present in quantities of 10 20 or 40 10 40 20 60 40 90 access articles at www.gsajournals.org 8 thegeologicalsocietyofamericap o b o x 914 0 · boulder c o 8 0 3 01 914 0 u s a
