Download or read book Devonian Events and Correlations written by R. T. Becker and published by Geological Society of London. This book was released on 2007 with total page 296 pages. 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.

Download or read book Paleozoic Stratigraphy and Resources of the Michigan Basin written by G. Michael Grammer and published by Geological Society of America. This book was released on 2018-04-12 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Michigan Basin is a classic intracratonic basin that has played a significant role in the fundamental understanding of geological processes in such basins, and has been an important resource for oil and gas, economic minerals, groundwater, and coal. Despite the classic nature of the Michigan Basin, there has not been a "special volume" dedicated to the basin in nearly 25 years. Since that time, new advancements in the geological sciences, particularly the utilization of high-resolution sequence stratigraphy and three-dimensional geostatistical modeling, have led to a new and more comprehensive understanding of the Paleozoic sedimentary packages of the Michigan Basin. This volume provides significant new insights of the Michigan Basin to both academic and applied geoscientists; it includes papers that discuss various aspects of the sedimentology and stratigraphy of key units within the basin, as well as papers that analyze the diverse distribution of natural resources present in this basin.
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.
