Available in PDF, EPUB and Kindle. Book excerpt: The Early Cretaceous (Barremian-Albian) Burro Canyon Formation in Eastern Utah and Western Colorado is a dominantly fluvial system that resembles the Cedar Mountain Formation, a correlative unit that lies across the Colorado River and is famous for recent dinosaur discoveries, The Burro Canyon Formation is arbitrarily split from the Cedar Mountain Formation using the Colorado River as a dividing line. This non-stratigraphic means of splitting one unit from the other is largely due to convention and it has become entrenched in the literature. Sections measured on Hotel Mesa and Buckhorn Mesa, both in eastern Grand County, Utah, were made in order to better delineate the contact between the two formations in this remote area on the Uncompahgre Plateau. The section on Hotel Mesa is in the Poison Strip Sandstone Member of the Cedar Mountain Formation as demonstrated by correlation to nearby established measured sections. Multiple paleocurrents were taken on Buckhorn Mesa, along with three new measured sections. These measured sections and paleoflows were then used to determine whether these rocks are likely to be in the Burro Canyon Formation or the Cedar Mountain Formation. Facies were established for the outcrops, with preliminary facies associations then being developed and outlined on photographs. Analyses show that these fluvial sandstones on this edge of the Uncompahgre Plateau are all in the Poison Strip Sandstone Member of the Cedar Mountain Formation. Also, no other Early Cretaceous sediments are found on this entire portion of the Plateau, as illustrated using panoramic photographs.

Book Synopsis Cedar Mountain and Dakota Formations Around Dinosaur National Monument by : Douglas A. Sprinkel
Download or read book Cedar Mountain and Dakota Formations Around Dinosaur National Monument written by Douglas A. Sprinkel and published by Utah Geological Survey. This book was released on 2012 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 20 page report describes the stratigraphy of the Cedar Mountain and Dakota formations in and around Dinosaur National Monument in northeast Utah and includes new palynology and radiometric age data. The contract between these formations is unconformable in which the Dakota formation has incised into the underlying Cedar Mountain formation. Locally, the Dakota includes a basal marine mudstone and shale unit that contains late Albian dinoflagellate cysts, which represents peak sea level during the Kiowa-Skull Creek depositional cycle and indicates the first marine incursion of the Cretaceous Western Interior Seaway into Utah.

Book Synopsis Stable Isotope Studies of the Water Cycle and Terrestrial Environments by : A-V. Bojar
Download or read book Stable Isotope Studies of the Water Cycle and Terrestrial Environments written by A-V. Bojar and published by Geological Society of London. This book was released on 2021-11-09 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is devoted to Earth surface environmental reconstructions and environmental changes that may be deciphered and modelled using stable isotopes along with mineralogical/chemical, sedimentological, palaeontological/biological and climatological methodologies. The book is divided into two sections, both using stable isotopes (see www.geolsoc.org.uk/SP507) in various samples and phases as the main research tool. The first section is devoted to studies focusing on the distribution of isotopes in precipitation, groundwater, lakes, rivers, springs, tap water, mine water and their relationship with terrestrial environments at regional to continental scale. In relation to this, the second section includes case studies from a range of continental settings, investigating cave deposits (stalagmites, bat guano), animal skeletons (dinosaurs, alligators, turtles, bivalves), present and past soils (palaeosols) and limestones. The sections focus on the interaction between the surficial water cycle and underground water storage with deposits acting as archives of short- to long-term climatic and environmental changes. Examples from the Early Cretaceous to present time come from Europe, Asia, Africa, North and South America.

Book Synopsis Vertebrate Paleontology in Utah by : David D. Gillette
Download or read book Vertebrate Paleontology in Utah written by David D. Gillette and published by Utah Geological Survey. This book was released on 1999 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 52 papers in this vary in content from summaries or state-of-knowledge treatments, to detailed contributions that describe new species. Although the distinction is subtle, the title (Vertebrate Paleontology in Utah) indicates the science of paleontology in the state of Utah, rather than the even more ambitious intent if it were given the title “Vertebrate Paleontology of Utah” which would promise an encyclopedic treatment of the subject. The science of vertebrate paleontology in Utah is robust and intense. It has grown prodigiously in the past decade, and promises to continue to grow indefinitely. This research benefits everyone in the state, through Utah’s muse ums and educational institutions, which are the direct beneficiaries.
Book Synopsis A Taphonomic Study of Selected Sites in the Poison Strip Sandstone and Ruby Ranch Members of the Cedar Mountain Formation (Lower Cretaceous), East Central Utah by : David A. Lee
Download or read book A Taphonomic Study of Selected Sites in the Poison Strip Sandstone and Ruby Ranch Members of the Cedar Mountain Formation (Lower Cretaceous), East Central Utah written by David A. Lee and published by . This book was released on 2014 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taphonomic characteristics were explored and described in order to understand the relationship between preservation of vertebrate fossils and corresponding lithostratigraphic units in the upper Cedar Mountain Formation of east-central Utah. This was accomplished through collection, analysis, and interpretation of taphonomic data collected from fossil specimens and their corresponding stratigraphic units from two localities: Tonys Bone Bed (Poison Strip Sandstone Member) and Lorries Site (Ruby Ranch Member). In addition to original quarry descriptions and assemblage information, taphonomic data were collected, including weathering and abrasion, which were compared by locality and element shape in order to determine their relationship. Data regarding fracturing and breakage were also collected and analyzed in order to better understand the post-depositional conditions of bone degradation. Both localities were described and characterized by weathering traits, abrasion traits, degree of articulation, preferred long bone orientation, and corresponding lithofacies. Tonys Bone Bed is characterized by less prominent degrees of weathering and differential transport abrasion by element shape, as well as preferred long-bone orientation, and corresponds to a lake margin debris flow and pedogenically altered overbank deposit. Lorries Site is characterized by more pronounced weathering, which is differentiated based on element shape, prominent long-bone orientation, and corresponds to a crevasse splay deposit with carbonate concretionary development.
Book Synopsis U-Pb Detrital Zircon Geochronology of Lower Cretaceous Cedar Mountain and San Pitch Formations in Central-eastern, Utah by : Gary J. Hunt
Download or read book U-Pb Detrital Zircon Geochronology of Lower Cretaceous Cedar Mountain and San Pitch Formations in Central-eastern, Utah written by Gary J. Hunt and published by . This book was released on 2015 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of U-Pb ages of detrital zircons from synorogenic Lower Cretaceous (Barremain-Albian) Cedar Mountain and San Pitch formation conglomerates and sandstones (N = 7, n = 641) preserved in the Sevier foreland basin of Utah are statistically related to age spectra of detrital zircons in Jurassic-Neoproterozoic strata (N = 11, n = 1104) in the Cordilleran fold-thrust belt. A history of Sevier thrust-belt unroofing, reworking, and recycling of detritus is recorded in the distribution of detrital zircons in Lower Cretaceous foreland basin strata. Three geochronological provenance intervals are observed in Neoproterozoic-Jurassic strata in the thrust-belt that are also recognized in 3 inverted chronofacies in foreland basin strata. The first provenance interval in the thrust belt is recognized as chronofacies A in the foreland basin. It is defined by a dominant group of Paleoproterozoic detrital zircons and the presence of significant numbers of Late Neoproterozic-Early Paleozoic (550 - 300 Ma) grains. Quartzites and sandstones in the thrust belt in provenance interval 1 include Pennsylvanian-Permain Oquirrh Formation, Permian Diamond Creek Sandstone, and the Jurassic Nugget Sandstone. Statistically related to provenance interval 1 are the oldest foreland basin strata in chronofacies A, including the Buckhorn Conglomerate Member of the Cedar Mountain Formation on the San Rafael Swell, and the Yellow Cat and Poison Strip Sandstone members in eastern Utah. The second provenance is observed in Ordovician-Devonian strata in the Canyon Range thrust sheet, and chronofacies B in the foreland basin; these display mostly Paleoproterozoic detrital zircons with dominant age groups of 1.8-1.9 Ga and 2.2-2.4 Ga. Cedar Mountain Formation conglomerates at the base of the Cretaceous succession in Salina Canyon on the southwestern Wasatch Plateau, and the Short Canyon Conglomerate (Upper Albain) on the western San Rafael Swell, are statistically related to detrital zircon age spectra observed in the Eureka (Ordovician) and Cove Fort (Devonian) quartzites in the thrust-belt. The third provenance interval observed constitutes Neoproterozoic and Cambrian quartzites from the Canyon Range thrust sheet and chronofacies C in the foreland basin, which all produce a tri-modal population of Mesoproterozoic (1.0-1.2 Ga), Paleoproterozoic (1.4 Ga and 1.6-1.8 Ga), and a subordinate population of Archean (>2.5 Ga) grains. Upper Albian conglomerates of the San Pitch Formation produced detrital zircon grains that were derived primarily from the oldest allochthonous strata in the thrust sheet, thus recording the complete unroofing of the thrust-belt in Early Cretaceous time. Abundant Mesozoic detrial zircon grains were sampled in distal Cedar Mountain Formation samples, whereas in more proximal deposits of the Buckhorn Conglomerate on the San Rafael Swell, Cordilleran arc grains are rare. This is due to different sediment dispersal patterns and involves recycling of detrital zircons from reworked Mesozoic strata and perhaps transported directly from Jurassic plutons in the southern Mogollon Highlands. The Buckgorn Conglomerate was deposited by braided transverse rivers with headwaters in the Sevier highlands that produce minimal Triassic-Jurassic detrital zircons, whereas distal deposits of the Yellow Cat and Poison Strip Sandstone members were deposited in a distal axial river system with headwaters in the Mogollon highlands where Triassic-Jurassic zircons are plentiful. Three stages of the early Cretaceous foreland basin in Utah are recognized. An initial stage, which was controlled predominantly by dynamic subsidence, is recognized by the slow deposition of Barremian-Aptian strata of the lower Cedar Mountain Formation (e.g. Buckhorn Conglomerate) with no evidence of a clastic wedge developement to the west. The second stage is the observance of the first westward thickening wedge of sediment recognized in Aptian-Albian Cedar Mountain Formation (Ruby Ranch Member); this indicates that the flexural component of the foreland basin began in Late Aptian or later.The final stage of Early Cretaceous thrust-belt unroofing is recognized with deposition of the San Pitch Formation on proximal axial rivers in an actively subsiding foredeep depozone during latest Albian time.

Download or read book A Taphonomic Study of Selected Fossil Sites in the Lower Cretaceous Yellow Cat Member, Cedar Mountain Formation in East-central Utah written by Matthew L. Howard and published by . This book was released on 2014 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: There appear to be significant differences among taphonomic variables of vertebrate fossils from three selected paleontological localities in the lower Cretaceous Yellow Cat Member of the Cedar Mountain Formation in east-central Utah. The taphonomic variables include weathering, abrasion, and fracturing. The specific sites that were studied are Doellings Bowl, Dalton Wells, and Gaston Quarry. The quarries are located on federal- and state-owned land and have well established fossil collections. This work focused on assessing whether there is an association of taphonomic variables with varying lithofacies in the Yellow Cat Member of the Cedar Mountain Formation. Analysis of the taphonomic variables was conducted, with the focus on weathering, abrasion, fracture, and breakage conditions. Utilizing Kruskal-Wallis, chi-square, and linear trend analyses, these taphonomic characters were compared 1) between localities and 2) between element classes (ex. rod-shaped bones vs. flat bones).

Book Synopsis A Fossil Locality Predictive Model for the Early Cretaceous Cedar Mountain Formation, Utah, USA by : Daniel Burk
Download or read book A Fossil Locality Predictive Model for the Early Cretaceous Cedar Mountain Formation, Utah, USA written by Daniel Burk and published by . This book was released on 2014 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hard work and chance are nearly always among the deciding factors in finding new, important, and productive paleontological localities. Fossil locality predictive models have the potential to reduce unproductive field time and maximize hard work thus increasing the chances researchers have to find important localities. This study uses remotely sensed data to design and test a fossil locality predictive model for the Early Cretaceous Cedar Mountain Formation. Landsat 8 OLI/TIRS data from known localities were summarized, reclassified and used in a weighted suitability analysis to categorize fossil locality potential of the study area. Field work was conducted to test model functionality. Field observations were used to refine the weighted suitability analysis. Landsat 8 OLI/TIRS data alone offers a less accurate prescription of fossil locality potential. Additional physical and environmental factors play a role in determining the chance of finding fossils. Slope degree and aspect data from known localities were summarized and analyzed to further refine the model. The usefulness of fossil locality predictive models is dependent upon the quality of input data and methods used to determine fossil locality potential. In order to fully determine the quality of a fossil locality predictive model, field work testing the model must be conducted.
