Book Description




The Evolution of the Rheic Ocean


Book Description

Geological evolution of middle to late Paleozoic rocks in the Avalon terrane of northern mainland Nova Scotia, Canadian Appalachians: a record of tectonothermal activity along the northern margin of the Rheic Ocean in the Appalachian-Caledonide orogen.




The Variscan Orogeny


Book Description

This volume summarizes the state of the art of Variscan geology from Iberia to the Bohemian Massif. The European Variscan belt consists of two orogens: the older, northern and the younger, southern. The northern Variscan realm was dominated by Late Devonian–Carboniferous rifting, subduction and collisional events as defined by sedimentary records, crustal growth, recycling of continental crust and large-scale deformations. In contrast, the southern European crust was reworked by major Late Carboniferous collision followed by Permian wrenching. The Late Carboniferous–Permian orogeny overprinted the previously accreted system in the north, but with much lower intensity, resulting in magmatic recycling and extensional tectonics. These two main orogenic cycles do not reflect episodic evolution of a single orogenic system but a complete change in orientation of stress field, thermal regime, degree of reworking and recycling of European crust, reflecting a major switch in plate configurations at the Early–Late Carboniferous boundary.




The Geology of Iberia: A Geodynamic Approach


Book Description

Taking a new global approach, this unique book provides an updated review of the geology of Iberia and its continental margins from a geodynamic perspective. Owing to its location close to successive plate margins, Iberia has played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys s.l. and Eurasian plates over the last 600 Ma of Earth's history. The geological record starts with the amalgamation of Gondwana in the Neoproterozoic succeeded by the rifting and spreading of the Rheic ocean; its demise, which led to the amalgamation of Pangea in the late Paleozoic; the rifting and spreading of several arms of the Neotethys ocean in the Mesozoic Era and their ongoing closure, which was responsible for the Alpine orogeny. The significant advances in the last 20 years have attracted international research interest in the geology of the Iberian Peninsula. This volume presents the most comprehensive, careful and updated description of the variscan cycle in Iberia. This volume focuses in the different geological events since the Cambrian-Early Ordovician rift until the late variscan orocline formations including magmatic and metamorphic evolution.




The Geology of Central Europe: Precambrian and Palaeozoic


Book Description

Publishers Weekly Top 10 Best of the Year In her new collection, Story Prize finalist Maureen F. McHugh delves into the dark heart of contemporary life and life five minutes from now and how easy it is to mix up one with the other. Her stories are post-bird flu, in the middle of medical trials, wondering if our computers are smarter than us, wondering when our jobs are going to be outsourced overseas, wondering if we are who we say we are, and not sure what we'd do to survive the coming zombie plague. Praise for Maureen F. McHugh: "Gorgeously crafted stories."—Nancy Pearl, NPR "Hauntingly beautiful."—Booklist "Unpredictable and poetic work."—The Plain Dealer Maureen F.

4-D Framework of Continental Crust


Book Description

"This book contains landmark papers on the processes of formation of continental crust from its beginnings in the Archean to modern processes, as well as discussions of several ancient and modern orogenic belts. The book is international in scope, with contributions from geoscientists dealing with crustal processes on five continents, and articles from more than 50 non-U.S. authors and co-authors."--Publisher's website.




From Rodinia to Pangea


Book Description

"The Appalachians constitute one of Earth's major tectonic features and have served as a springboard for innovative geologic thought for more than 170 years. This volume contains 36 original papers reporting the results of research performed throughout nearly the entire length and breadth of the Appalachian region, including all major provinces and geographical areas. Memoir 206 was designed to commemorate the (near-)fortieth anniversary of the publication of the classic Studies of Appalachian Geology volumes that appeared just prior to the application of plate tectonic concepts to the region. Contributions concerning structural evolution, sedimentation, stratigraphy, magmatic processes, metamorphism, tectonics, and terrane accretion illustrate the wide range of ongoing research in the area and collectively serve to mark the considerable progress in scientific thought that has occurred during the past four decades."--pub. desc.




Resolving the Late Paleozoic Ice Age in Time and Space


Book Description

"This volume summarizes new developments in understanding the longest-lived icehouse period in Phanerozoic Earth history, the late Paleozoic ice age. Resolving the Late Paleozoic Ice Age in Time and Space provides summaries of existing and new data from the various Gondwanan continental relics, and also reviews stratigraphic successions from the paleotropical and temperate regions of Laurussia that preserve an indirect record of glaciation. It addresses the extent to which records of glaciation indicate protracted, long-term climatic austerity, as opposed to fluctuating, more dynamic climate, and provides new constraints on the timing of glaciation. Additionally, it tackles questions of synchroneity of glaciation across the various Gondwanan continental relics, and timing relationships between near-field and far-field records at greater levels of resolution than has been possible previously. Results point toward a dynamic icehouse regime that is comparable to the Cenozoic icehouse, and away from traditional interpretations of the late Paleozoic ice age as a single, protracted event that involved stable, long-lived ice centers."--Publisher's website.




Ice Ages, Climate Dynamics and Biotic Events: The Late Pennsylvanian World


Book Description

The Late Pennsylvanian was a time of ice ages and associated climate dynamics. A major reduction in Gondwana ice-volume was followed by a prolonged period of relative global warmth, culminating in the last great ice age of the late Paleozoic. It also was a major turning point in the evolution of life on land, when the coal forests of the Middle Pennsylvanian gave way to new kinds of Late Pennsylvanian wetland vegetation, and new kinds of animals appeared. Changes in the terrestrial biota began during the Middle Pennsylvanian, accelerating and proceeding in a spatially complex manner throughout the Late Pennsylvanian. The Late Pennsylvanian is thus a laboratory for studying environmental changes in a glacial world, and for assessing coeval biotic changes, in part to establish the possible links between the two. No book has been dedicated to this time interval, so this volume fills a gap in our understanding of a dynamic Late Pennsylvanian world that is much like the late Cenozoic world.




Geological Development of Anatolia and the Easternmost Mediterranean Region


Book Description

Anatolia and the easternmost Mediterranean region, especially Turkey, Cyprus and northern Syria, represent an excellent natural laboratory for the study of fundamental geological processes (e.g. rifting, seafloor spreading, ophiolite genesis and emplacement, subduction, exhumation and collision). Their interaction has created an intriguing array of deep-sea basins, microcontinents and suture zones.The volume's 22 papers include a large amount of new field-based information (much of it multidisciplinary and the product of teamwork). After an overview, the volume is divided into four sections: Late Palaeozoic--Early Cenozoic of the Pontides (northern Turkey); Late Palaeozoic--Early Cenozoic of the Taurides--Anatolides (central and southern Turkey); Late Cretaceous--Pliocene sedimentary basins and structural development (central Anatolia to the Mediterranean); Late Miocene--Recent Neotectonics (southern Turkey, Cyprus and northern Syria). The volume will interest numerous academic researchers, those concerned with resources (e.g. hydrocarbons; mineral deposits) and also hazards (e.g. earthquakes), as well as advanced undergraduate and postgraduate students -- P. 4 of cover.
