Download or read book Quaternary Deformation of the Middle Pleistocene Christmas Canyon Formation and Its Implications for Neotectonic Processes Associated with the Garlock Fault and Eastern California Shear Zone written by Evan Michael Wolf and published by . This book was released on 2013 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Searles Valley region of southeastern California exhibits a series of northeasterly trending folds that are anomalously oriented when viewed in the context of the current regional stress field, where the principal compressive stress is oriented from the northeast and southwest. This region also marks a complex zone of deformation, as the Blackwater fault of the Eastern California Shear Zone (ECSZ) appears to terminate at its intersection with the Browns Valley/Ranch fault zone, 5 km south of the Garlock fault. The presence of the northeasterly trending Christmas Canyon anticline near the junction of these three fault systems has led to the inference that regional compression directed from the northwest and southeast may have occurred during the last 640,000 years. To assess the style of deformation associated with the interaction of these three fault zones, a geologic survey consisting of geologic mapping, remote sensing and absolute-dating techniques was conducted within the northeastern Lava Mountains, immediately south of the Garlock fault. The study area, informally designated as western Christmas Canyon, exhibits a series of northeasterly trending structures that have deformed and offset lacustrine deposits of the middle Pleistocene Christmas Canyon Formation. These northeasterly striking faults, exhibit displacements suggestive of sinistral shear, and are oriented on average 22 degrees counterclockwise to the trace of the Garlock fault in southern Searles Valley. The orientation and mode of deformation attributed to these faults implies that they may have formed as Riedel shears to the sinistral Garlock fault zone, and thus likely formed during a period of northeast-southwest directed regional compression. Conversely, a single northeast-trending synclinal structure within western Christmas Canyon implies regional compression nearly orthogonal to the adequate orientation for driving sinistral shear along the Garlock fault zone. The results obtained from the geologic survey of the western Christmas Canyon region imply that the Garlock fault has sinistrally offset two alluvial fan surfaces from their source drainage during the late Holocene, and that a period of northwest-southeast directed compression most likely did not occur since the deposition of the middle Pleistocene Christmas Canyon Formation. As a result, the formation of northeasterly trending folds within the Christmas Canyon Formation is inferred to be attributed to deformation associated with slip along Riedel shears of the Garlock fault zone, or as a result of distributed deformation associated with the termination of northwesterly striking dextral faults of the Eastern California Shear zone or P' shears to the Garlock fault.

Download or read book Remote Sensing Geology written by Ravi P. Gupta and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly three decades there has been a phenomenal growth in the field of Remote Sensing. The second edition of this widely acclaimed book has been fully revised and updated. The reader will find a wide range of information on various aspects of geological remote sensing, ranging from laboratory spectra of minerals and rocks, ground truth, to aerial and space-borne remote sensing. This volume describes the integration of photogeology into remote sensing as well as how remote sensing is used as a tool of geo-exploration. It also covers a wide spectrum of geoscientific applications of remote sensing ranging from meso- to global scale. The subject matter is presented at a basic level, serving students as an introductory text on remote sensing. The main part of the book will also be of great value to active researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Petrochronology is a rapidly emerging branch of Earth science that links time (ages or rates) with specific rock-forming processes and their physical conditions. It is founded in petrology and geochemistry, which define a petrogenetic context or delimit a specific process, to which chronometric data are then linked. This combination informs Earth’s petrogenetic processes better than petrology or geochronology alone. This volume and the accompanying short courses address three broad categories of inquiry. Conceptual approaches chapters include petrologic modeling of multi-component chemical and mineralogic systems, and development of methods that include diffusive alteration of mineral chemistry. Methods chapters address four main analytical techniques, specifically EPMA, LA-ICP-MS, SIMS and TIMS. Mineral-specific chapters explore applications to a wide range of minerals, including zircon (metamorphic, igneous, and detrital/Hadean), baddeleyite, REE minerals (monazite, allanite, xenotime and apatite), titanite, rutile, garnet, and major igneous minerals (olivine, plagioclase and pyroxenes). These applications mainly focus on metamorphic, igneous, or tectonic processes, but additionally elucidate fundamental transdisciplinary progress in addressing mechanisms of crystal growth, the chemical consequences of mineral growth kinetics, and how chemical transport and deformation affect chemically complex mineral composites. Most chapters further recommend areas of future research.

Download or read book Paleopalynology written by Alfred Traverse and published by Springer Science & Business Media. This book was released on 2007-05-21 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.
Download or read book Conservation Paleobiology written by Gregory P. Dietl and published by University of Chicago Press. This book was released on 2017-11-17 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: In conservation, perhaps no better example exists of the past informing the present than the return of the California condor to the Vermilion Cliffs of Arizona. Extinct in the region for nearly one hundred years, condors were successfully reintroduced starting in the 1990s in an effort informed by the fossil record—condor skeletal remains had been found in the area’s late-Pleistocene cave deposits. The potential benefits of applying such data to conservation initiatives are unquestionably great, yet integrating the relevant disciplines has proven challenging. Conservation Paleobiology gathers a remarkable array of scientists—from Jeremy B. C. Jackson to Geerat J. Vermeij—to provide an authoritative overview of how paleobiology can inform both the management of threatened species and larger conservation decisions. Studying endangered species is difficult. They are by definition rare, some exist only in captivity, and for those still in their native habitats any experimentation can potentially have a negative effect on survival. Moreover, a lack of long-term data makes it challenging to anticipate biotic responses to environmental conditions that are outside of our immediate experience. But in the fossil and prefossil records—from natural accumulations such as reefs, shell beds, and caves to human-made deposits like kitchen middens and archaeological sites—enlightening parallels to the Anthropocene can be found that might serve as a primer for present-day predicaments. Offering both deep-time and near-time perspectives and exploring a range of ecological and evolutionary dynamics and taxa from terrestrial as well as aquatic habitats, Conservation Paleobiology is a sterling demonstration of how the past can be used to manage for the future, giving new hope for the creation and implementation of successful conservation programs.
