Book Description
Tectonic Evolution, Collision, and Seismicity of Southwest Asia
Author: Rasoul SorkhabiPublisher: Geological Society of America
ISBN: 0813725259
Category : Science
Languages : en
Pages : 684
Book Description
Southwest Asia is one of the most remarkable regions on Earth in terms of active faulting and folding, large-magnitude earthquakes, volcanic landscapes, petroliferous foreland basins, historical civilizations as well as geologic outcrops that display the protracted and complex 540 m.y. stratigraphic record of Earth's Phanerozoic Era. Emerged from the birth and demise of the Paleo-Tethys and Neo-Tethys oceans, southwest Asia is currently the locus of ongoing tectonic collision between the Eurasia-Arabia continental plates. The region is characterized by the high plateaus of Iran and Anatolia fringed by the lofty ranges of Zagros, Alborz, Caucasus, Taurus, and Pontic mountains; the region also includes the strategic marine domains of the Persian Gulf, Gulf of Oman, Caspian, and Mediterranean. This 19-chapter volume, published in honor of Manuel Berberian, a preeminent geologist from the region, brings together a wealth of new data, analyses, and frontier research on the geologic evolution, collisional tectonics, active deformation, and historical and modern seismicity of key areas in southwest Asia.
A Global Synthesis of the Ordovician System: Part 1
Author: D.A.T. HarperPublisher: Geological Society of London Special Publications
ISBN: 1786205882
Category : Science
Languages : en
Pages : 514
Book Description
The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. This first volume (SP532) charts the history of the Ordovician System and explores significant advances in our understanding of its biostratigraphy, including more precise calibration of its timescale with tephra chronology and regional alignments using astrochronology and cyclostratigraphy. Changes in the world’s oceans, their shifting currents and sea levels, the biogeography of their biotas and the ambient climate are described and discussed against a background of changing palaeogeography. This first volume also includes syntheses of the Ordovician geology for most European countries, including historical key areas, such as Great Britain, Baltoscandia and Bohemia. The second volume (SP533) provides synthetic aspects of the Ordovician geology of most other parts of the world.

The Great Ordovician Biodiversification Event

Pages : 497
Book Description
Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. During the 46-million-year Ordovician Period (489–443 m.y.), a bewildering array of adaptive radiations of "Paleozoic- and Modern-type" biotas appeared in marine habitats, the first animals (arthropods) walked on land, and the first non-vascular bryophyte-like plants (based on their cryptospore record) colonized terrestrial areas with damp environments. This book represents a compilation by a large team of Ordovician specialists from around the world, who have enthusiastically cooperated to produce this first globally orientated, internationally sponsored IGCP (International Geological Correlation Program) project on Ordovician biotas. The major part is an assembly of genus- and species-level diversity data for the many Ordovician fossil groups. The book also presents an evaluation of how each group diversified through Ordovician time, with assessments of patterns of change and rates of origination and extinction. As such, it will become the standard work and data source for biotic studies on the Ordovician Period.
