This book was released on 2009 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: The provenance, stratigraphy, and depositional history of the Miocene-Pliocene Muddy Creek Formation (MCF) in southern Nevada are poorly studied and poorly constrained. Previous studies of the MCF have concluded that the formation consists of lacustrine, eolian, and fluvial deposits. Currently the age of deposition is loosely constrained between 8.5 and 4.1 Ma. This study documents the evolution of one portion of the eastern extent of the MCF and determines its provenance and depositional history at Flat Top and Mormon Mesas in Nevada; and near Beaver Dam and Littlefield, Arizona. This study intended to determine whether the MCF was deposited by a paleo-Colorado River that flowed through the Virgin River Gorge and into the Mesquite basin prior to ~5.5 Ma. Methods used in this study included petrographic analyses, detrital zircon analyses, facies analyses, paleocurrent indicators, and conglomerate clast counts. Detrital zircons from the MCF, a Pliocene unit near Littlefield, Arizona, and modern day Virgin River were compared to previously analyzed zircons from the Bidahochi Formation and known Colorado River zircons. Results from the MCF in the Beaver Dam Wash and at Flat Top Mesa indicate paleotransport was to the south-southeast and south-southwest respectively and in an inset Pliocene unit near Littlefield, Arizona paleotransport was to the south-southwest. Based upon sedimentological data the MCF within the study area was deposited in a fluvial environment. Conglomerate clasts and sandstone petrography from the MCF at Mormon Mesa indicate mixed volcanic, metamorphic, and sedimentary sources for the sediment which is dissimilar to deposits at Flat Top Mesa and Beaver Dam Wash which were derived from a volcanic source. The provenance data indicate the MCF at Flat Top Mesa and Beaver Dam Wash were derived from the Caliente Caldera complex, while the deposits at Mormon Mesa were derived from both the Caliente Caldera complex and the Colorado Plateau, which was deposited by a paleo-Virgin River. Results from an inset Pliocene unit in the Beaver Dam Wash indicate this unit was derived from the Caliente Caldera complex. In contrast, results from an inset Pliocene unite near Littlefield, Arizona indicate it was derived from the Colorado Plateau and deposited by a paleo-Virgin River. Despite the MCF at Mormon Mesa having a partial Colorado Plateau provenance results are consistent with previous models that indicated that neither the younger units nor the portions of the MCF that were studied were deposited by a paleo-Colorado River.

Download or read book Sandstone Petroleum Reservoirs written by John H. Barwis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sandstone Petroleum Reservoirs presents an integrated, multidisciplinary approach to the geology of sandstone oil and gas reservoirs. Twenty-two case studies involving a variety of depositional settings, tectonic provinces, and burial/diagenetic histories emphasize depositional controls on reservoir architecture, petrophysical properties, and production performance. An introductory section provides perspective to the nature of reservoir characterization and highlights the important questions that future studies need to address. A "reservoir summary" following each case study aids the reader in gaining quick access to the main characteristics of each reservoir. This casebook is heavily illustrated, and most data have not been previously published. The intended audience comprises a broad range of practicing earth scientists, including petroleum geologists, geophysicists, and engineers. Readers will value the integration of geological versus engineering interests provided here, and will be enabled to improve exploration and production results.

Available in PDF, EPUB and Kindle. Book excerpt: This volume describes and explores the emerging discipline of conservation paleobiology, and addresses challenges faced by established and young Conservation Paleobiologist's alike. In addition, this volume includes applied research highlighting how conservation paleobiology can be used to understand ecosystem response to perturbation in near and deep time. Across 10 chapters, the book aims to (1) explore the goals of conservation paleoecology as a science, (2) highlight how conservation paleoecology can be used to understand ecosystems’ responses to crises, (3) provide case studies of applications to modern ecosystems, (4) develop novel applications of paleontological approaches to neontological data, and (5) present a range of ecosystem response and recovery through environmental crises, from high-resolution impacts on organism interactions to the broadest scale of responses of the entire marine biosphere to global change. The volume will be of interest to paleoecologists, paleobiologists, and conservation biologists.
