processes on the early earth edited by wolf uwe reimold and roger l gibson 2006 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 spe405 402 p plus index

geochemistry a tribute volume to derek c ford and william b white edited by russell s harmon and carol m wicks 2006 over the past half-century derek c ford and william b white established the foundation and framework within which geomorphological hydrological and geochemical studies of caves and karst are conducted in north america this was accomplished through almost entirely independent parallel and complementary research and teaching career paths this volume contains papers derived from a representative cross section of the papers presented at the gsa meeting plus a small number of additional volunteered contributions the general theme of the book is the diversity and breadth of geomorphological hydrological and geochemical research currently being conducted by the karst research community in north america and around the world ford and white each have contributed a retrospective contribution reviewing the progress in karst geomorphology and speleogenesis and karst hydrology over the past half-century the other contributions examine specifically how different facets of karst terrains are being studied in the early years of the twenty-first century spe404 344 p

most provocative recent plate-tectonic revelation is that continental crust was subducted to depths of >100 km and exhumed at numerous locations worldwide throughout the phanerozoic it is now recognized that the formation and exhumation of these ultrahigh-pressure or uhp rocks is an inherent and fundamental dynamic aspect of collisional orogenesis that affects a panoply of earth processes including but not limited to exchange of material between the crust and mantle the generation and collapse of mountain belts the formation of continental crust and the influence of uhp rock formation and exhumation on tectonic plate motions this volume presents a collection of papers highlighting recent discoveries in the field spe403 206 p isbn 0-8137-2403-9 $60.00 member price $42.00 penrose conference series neogene-quaternary continental margin volcanism a perspective from méxico edited by claus siebe josé luis macías and gerardo j aguirre-díaz 2006 this volume represents the culmination follow-up of a successful penrose conference held in january 2004 at the foot of popocatépetl volcano in central méxico where more than 100 specialists gathered to discuss magmatic arc volcanism in the americas petrological and geochemical issues eruption dynamics hazard studies and other topics relating to arc volcanoes were treated in great detail this volume includes the most recent advances in our knowledge of the subduction-related trans mexican volcanic belt this area is densely populated and includes some of the most beautiful but potentially most dangerous volcanoes in the world spe402 329 p isbn 0-8137-2402-3 $95.00 member price $67.00 new frontiers in dead sea paleoenvironmental research edited by yehouda enzel amotz agnon and mordechai stein 2006 this volume is a key contribution to anyone interested in the near east and its changing environments climate change natural hazards and lacustrine processes salt diapirs and age dating it presents new data and syntheses by active researchers of the dead sea basin one of the most historically geologically and hydrologically interesting lake basins in the world the dead sea holds a few records its shores are at the lowest elevation on the continents and its water is among the most saline and dense in the world it is a place where humans have interacted with harsh environments and rough landscapes for a very long time this extremely arid lake basin is a challenge to modern societies some chapters cover natural hazards such as earthquakes and collapse sinkholes floods and flood-producing storms others contribute to understanding the scarce water resources of surface and ground water in the area shore and lake depositional processes the evolution of the lake water and age dating methods also are presented and are used in reconstructing the lake levels and the near east climate change in historical and prehistorical times the interaction of people and their use of the shores and the fascination nineteenth century travelers had with the lake are also presented spe401 253 p isbn 0-8137-2401-5 $80.00 member price $56.00 new frontiers in dead sea paleoenvironmental research edited by
