Download or read book The Triassic Timescale written by Spencer G. Lucas and published by Geological Society of London. This book was released on 2010 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mesozoic Era begins with the approximately 50-million-year-long Triassic Period, a major juncture in Earth history when the vast Pangaean supercontinent completed its assembly and began its fragmentation, and the global biota diversified and modern-ized after the end-Permian mass extinction, the most extensive biotic decimation of the Phanerozoic. The temporal ordering of geological and biotic events during Triassic time thus is critical to the interpretation of some unique and pivotal events in Earth his-tory. This temporal ordering is mostly based on the Triassic time-scale, which has been developed and refined for nearly two centu-ries. This book reviews the state of the art of the Triassic timescale and includes comprehensive analyses of Triassic radio-isotopic ages, magnetostratigraphy, isotope-based and cyclostratigraphic correlations and timescale -relevant marine and non-marine bio-stratigraphy.

Download or read book The Pennsylvanian early Permian Bird Spring Carbonate Shelf Southeastern California written by Calvin H. Stevens and published by Geological Society of America. This book was released on 2007-01-01 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Bird Spring Shelf in southeastern California, along with coeval turbidite basins to the west, records a complex history of Pennsylvanian and Early Permian sedimentation, sea-level changes, and deformation along this part of the western North American continental margin. In this work we describe and figure the fusulinids, including several new species, and establish detailed correlations between deposits of the shelf and the flanking basins. We then use these correlations to reconstruct the depositional history, paleogeography, and deformational history of the region. This work adds significant detail to existing interpretations of the late Paleozoic as a time of major tectonic instability on the continental margin of southeastern California as it changed from a relatively passive margin, which had persisted through most of the Paleozoic, to an active convergent margin that would characterize the Mesozoic."--Publisher's website.

Available in PDF, EPUB and Kindle. Book excerpt: The Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field. - The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access - Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility - Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events - Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)

Download or read book The Great Paleozoic Crisis written by Douglas H. Erwin and published by Columbia University Press. This book was released on 1993 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Download or read book Anatomy of a Paleozoic Basin written by Stephen C. Ruppel and published by . This book was released on 2019-04-15 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anatomy of a Paleozoic Basin: The Permian Basin, USA By any standard, the Permian Basin of West Texas and New Mexico is a "super basin." With cumulative oil production of nearly 40 billion barrels (Bbbl) and annual production of nearly 2 Bbbl, it's currently one of the most important hydrocarbon-producing basins in the world. More than 29 Bbbl of this production have come from conventional (carbonate and sandstone) reservoirs, about 75 percent from carbonate reservoirs. Approximately 9-10 Bbbl of the basin's cumulative oil production have come from unconventional targets-primarily organic-matter-rich mudrocks and associated facies-during the last 10 years. The Permian Basin contains perhaps a greater volume of these mudrocks than that of any other basin, a major reason for its current global prominence among hydrocarbon-producing basins. The Permian Basin also contains one of the most extensive data sets in terms of wells drilled, cored wells, and adjacent outcrop analogs, providing a basis for studies that not only helps define the distribution of hydrocarbons but also serves as an excellent laboratory for examining basin-forming processes.This two-volume Bureau of Economic Geology Report of Investigations and AAPG Memoir contains 26 papers covering a breadth of Permian Basin topics, including 4 papers on the basin's structural geology, tectonics, and Precambrian geology; 4 papers on its paleontology and biostratigraphy; 16 on its sedimentology and stratigraphy; 1 on its reservoir systems; and 1 that provides a history and synthesis of the major depositional and deformational events that formed the basin. The goal of this set of papers is to capture, in a single publication, the wealth of information and knowledge about Permian Basin geology that has been generated over the 60 years that have passed since John Galley's early comprehensive paper on the basin in 1958.

Download or read book The Palynology and Micropalaeontology of Boundaries written by Alwynne Bowyer Beaudoin and published by Geological Society of London. This book was released on 2004 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores geological boundaries in time and space using palynology and micropalaeontology. Boundaries produce distinct signatures in the micropalaeontological record. They can tell us much about the response of biotic systems to environmental change in both marine and terrestrial realms. Different microfossil groups and geological contexts require their own approaches, definitions and considerations of boundaries. The papers here cover the methodology of boundary identification from biostratigraphical, ecological and palaeoenvironmental perspectives.
