Download or read book Precambrian to Earliest Mississippian Stratigraphy Geologic History and Paleogeography of Northwestern Colorado and West central Colorado written by James M. Soule and published by . This book was released on 1992 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The early Paleozoic of northwestern and west-central Colorado is represented by continental shelf and continental shelf marginal sedimentary rocks of Late Cambrian, Ordovician, and Late Devonian ages. Differentially epeirogenic movements along fracture systems having Precambrian origins affected sedimentation patterns and probably mostly account for intervening times of erosion or nondeposition; activity along these tectonic elements persisted into the Neogene and possibly continues. These tectonic elements are west-north-west, south-southeast, and northeast trending fracture systems and an east-trending aulacogen in the approximate area of the modern Uinta Mountains. North-central Colorado was emergent land throughout most of this time and shed clastic sediments at varying rates to the west and southwest. Episodic continental motion and the effects of the Antler orogeny to the west are probably the direct causes of these epeirogenic movements.
Download or read book Geological Evolution of the Earth During the Precambrian written by L.J. Salop and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in Precambrian geology has been exceptionally great, indeed quite striking for geologists of the older generation; only some 30-40 years ago the Precambrian appeared as an uncertain and even mystic prelude to geologic evolution. Even the very name - Precambrian - means some indi visible unit in the early history of the Earth, the beginning of which is poorly known. At the same time it was obvious that the Precambrian formations are of extremely varied and complex composition and poor knowledge and lack of reliable methods of division and correlation were to blame for the lack of significant progress in studies of this early evolutionary stage of the planet. Certainly, even at the very start of Precambrian studies, the results obtained were quite promising, lifting as they did the mysterious veil over the regional Precambrian; but they presented no general realistic picture of this early stage in the Earth's evolution at that time. Recently, this situation has completely changed, due to new methods of study of the older forma tions, and due also to the refinement of some well-known methods, in particular of division, dating, and correlation of "silent" metamorphic strata. Application of different isotope methods of dating was most impor tant in providing objective rock age and thereby the age of geologic events recorded in these rocks. Thus it became possible to reconstruct the oldest geologic period of our planet.

Download or read book The Precambrian Earth written by P.G. Eriksson and published by Elsevier. This book was released on 2004-03-04 with total page 967 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the editors strive to cover all primary (i.e. non-applied) topics in Precambrian geology in a non-partisan way, by using a large team of international authors to present their datasets and highly divergent viewpoints. The chapters address: celestial origins of Earth and succeeding extraterrestrial impact events; generation of continental crust and the greenstone-granite debate; the interaction of mantle plumes and plate tectonics over Precambrian time; Precambrian volcanism, emphasising komatiite research; evolution and models for Earth's hydrosphere and atmosphere; evolution of life and its influence on Precambrian ocean chemistry and chemical sedimentation; sedimentation through Precambrian time; the application of sequence stratigraphy to the Precambrian rock record. Each topic is introduced and a non-partisan closing commentary provided at the end of each chapter. The final chapter blends the major geological events and rates at which important processes occurred into a synthesis, which postulates a number of "event clusters" in the Precambrian when significant changes occurred in many natural systems and geological environments.

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 Geology of the Precambrian Superior and Grenville Provinces and Precambian Fossils in North America written by Stephen Bernard Lucas and published by . This book was released on 1998 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents three major contributions on aspects of Precambrian geology in North America. The first presents a comprehensive overview of the Archean Superior Province and its mineral resources to early 1995. It summarizes the major lithological and structural associations that comprise the province along with their inferred tectonic significance and that of the mineral deposits contained in each association. The major types of deposits are described in terms of their key geological affiliations and district-scale geological settings. Regional geology of the tectonic sub-provinces and their internal domains are reviewed and related to the time-space distribution of the deposits that they contain. Finally, the tectonic and metallogenic history of the Province is summarized and the numerous interpretations that have been put forward are discussed in light of current knowledge. The second contribution covers the Grenville Province (Mesoproterozoic) and its stratigraphic correlations, lithology, metamorphism, structure, geologic history, and tectonic models and their interpretations. The final contribution provides a general, current overview of the Precambrian fossil occurrences in North America and their stratigraphic distribution. Includes index.
