Available in PDF, EPUB and Kindle. Book excerpt: The Devonian was a peculiar period, characterized by simplified plate tectonic configurations, climatic overheating and widely flooded continents. The bloom of fishes and ammonoids, extensive reef complexes, and the conquest of land indicate major biosphere innovations, punctuated by many global events, including two of the biggest mass extinctions. The Devonian was the first system for which subdivisions were formally defined. This was achieved by significant advances in pelagic biostratigraphy. The chronostratigraphic framework and interdisciplinary techniques allow us to correlate intervals or sudden events across facies boundaries, in order to reconstruct the sedimentary and evolutionary history of the system with highest precision. This volume honors the lifetime stratigraphic achievements of Michael Robert House (1930-2002). Based on case studies from Europe, North Africa and North America, it shows how the combination of biostratigraphy, chemostratigraphy, magnetostratigraphy, sequence stratigraphy and event stratigraphy can contribute to a much deeper understanding of both regional and global environmental change.

Available in PDF, EPUB and Kindle. Book excerpt: "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.

Available in PDF, EPUB and Kindle. Book excerpt: A Comprehensive review of modern stratigraphic methods. The stratigraphic record is the major repository of information about the geological history of Earth, a record stretching back for nearly 4 billion years. Stratigraphic studies fill out our planet’s plate-tectonic history with the details of paleogeography, past climates, and the record of evolution, and stratigraphy is at the heart of the effort to find and exploit fossil fuel resources. Modern stratigraphic methods are now able to provide insights into past geological events and processes on time scales with unprecedented accuracy and precision, and have added much to our understanding of global tectonic and climatic processes. It has taken 200 years and a modern revolution to bring all the necessary developments together to create the modern, dynamic science that this book sets out to describe. Stratigraphy now consists of a suite of integrated concepts and methods, several of which have considerable predictive and interpretive power. The new, integrated, dynamic science that Stratigraphy has become is now inseparable from what were its component parts, including sedimentology, chronostratigraphy, and the broader aspects of basin analysis.

Download or read book Lower and Middle Devonian stratigraphy and depositional environments of the Sheep Desert Pintwater and Spotted Ranges Northern Clark County Nevada written by Linda Jane Jarvis and published by . This book was released on 1981 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: During much of the Early and Middle Devonian, shallow normal marine and peritidal sediments were deposited in northwestern Clark County, Nevada. Lack of a standard stratigraphic nomenclature for the area necessitates utilizing terminology from central Nevada and western Utah. The Sevy Dolomite represents Early Devonian deposition in a tidal flat environment. A Zlichovian transgression initiated deposition of the normal marine McColley Canyon Formation in the area. Continuation of that transgression was responsible for the deposition of the lower part of the Pintwater Formation, a new formation which consists of silty, argillaceous dolomite with abundant secondary chert. A Dalejan regression occurred during deposition of the upper part of the Pintwater Formation; it was during the later phases of this regression that the Oxyoke Canyon Sandstone was deposited in a complex barrier bar system which paralleled the coastline. Three Middle Devonian transgressions of varying magnitude have been recognized in southern Nevada. The first transgression, during the early Eifelian, was responsible for the widespread deposition of the Coarse Crystalline Member of the Simonson Dolomite. The Coarse Crystalline Member represents an entire transgressive-regressive cycle. The second Middle Devonian transgression, which occurred later in the Eifelian, initiated deposition of the restricted, shallow subtidal to supratidal Alternating Member of the Simonson Dolomite. Deposition of this unit was marked by periodic minor rises in sea level. Each dark-light dolomite couplet represents a single transgressive pulse followed by upward-shallowing sedimentation. Peritidal sedimentation was brought to an end by the third Middle Devonian transgression. This transgression, which occurred during the middle to late Givetian, brought the deeper water lithotope of the Guilmette Formation into the area. The tectonic setting in southern Nevada during the Early Devonian was significantly different than that in central Nevada; southern Nevada facies are different than central Nevada facies, and a relatively condensed conodont sequence indicates a slower rate of subsidence. During the Middle Devonian, however, facies throughout southern and east-central Nevada are markedly similar, as is the timing of depositional events. This indicates that the tectonic setting along the southern Cordilleran margin was more uniform by Middle Devonian time.
Download or read book Warm Climates in Earth History written by Brian T. Huber and published by Cambridge University Press. This book was released on 2000 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geologic record contains evidence of greenhouse climates in the earth's past, and by studying these past conditions, we can gain greater understanding of the forcing mechanisms and feedbacks that influence today's climate. Leading experts in paleoclimatology combine in one integrated volume new and state-of-the-art paleontological, geological, and theoretical studies to assess intervals of global warmth. The book reviews what is known about the causes and consequences of globally warm climates, demonstrates current directions of research on warm climates, and outlines the central problems that remain unresolved. The chapters present new research on a number of different warm climate intervals from the early Paleozoic to the early Cenozoic. The book will be of great interest to researchers in paleoclimatology, and it will also be useful as a supplementary text on advanced undergraduate or graduate level courses in paleoclimatology and earth science.
