Available in PDF, EPUB and Kindle. Book excerpt: The Upper Ordovician (450-460 Ma) Chazy, Black River and Trenton groups of eastern North America record the tectonic activation of a passive carbonate platform. Associated with tectonic collision and development of a peripheral-type foreland basin, the tectonic history is complicated by the occurrence of two basin-forming episodes. Although considered analogous by previous authors, a growing list of observations indicate that the stratigraphic record from both foreland basins and their coeval Great American Carbonate Bank (GACB) contain somewhat different, non-analogous, signatures. A number of key issues arise when comparing both tectonic episodes. These include: 1) non-analogous spatial-temporal scales whereby the northern (Vermontian) tectophase is much larger and of longer duration compared to the southern (Blountian) tectophase; 2) sedimentary provenance analyses show a more mafic contribution in the northern basin fill compared to that of the southern basin; 3) the position of K-bentonite swarms relative to basin filling phases is non-analogous; and 4) the location and timing of Ordovician volcanism/plutonism shows a pronounced change after the first tectophase. Thus, important research questions for this study include: A) How does the architecture of the foreland basin complex and adjacent GACB change spatially and temporally during each distinct tectophase?; B) Can provenance differences between tectophases be explained relative to tectonic events in the orogen?; C) What is the timing and significance of K-bentonite position and timing of plutonism/volcanism relative to foreland basin fill episodes?; 4) What inferences are gained from theoretical modeling of load geometries and foreland basin evolution when considered with empirical data from the Taconic Orogeny; and 5) Is a new model for the Taconic Orogeny needed to explain the growing list of incongruities? In order to investigate these questions, a refined, high-resolution, sequence stratigraphic framework has been constructed and utilized to re-calibrate Upper Ordovician strata during the last stand of the GACB. The refined framework was constructed using the occurrence of sequence boundaries, erosional surfaces, transgressive, highstand, and regressive systems tracts, hardgrounds and flooding surfaces, laterally extensive and unique lithofacies, highly repetitive sub-meter scale cyclic intervals, updated macrofaunal and microfaunal biostratigraphies, as well as known chemostratigraphic and event stratigraphic data (Nd, C, & Sr isotopic excursions, K-bentonite horizons, seismite horizons, etc.). Also defined for the first time are a number of time-restricted facies including widespread siliciclastic events, chert-rich intervals, and pronounced calcification events. As such, an improved temporal and spatial chronology of thirteen time-slices (~ 1 million year duration) has been produced for the Ashbyan, Mohawkian, to earliest Cincinnatian interval. This integrated stratigraphic model is used to link the sedimentary record of the foreland basin complex to climatic changes, sea-level oscillation, and specific tectonic events in the orogen. These data provide an understanding of the evolution of the foreland basin and its sub-components including the backbulge, forebulge, and foredeep basins. Moreover, coupled with newly calibrated strontium isotopic curves, this study has allowed for the development of a new model for the Taconic Orogeny that helps to explain differences in the timing and spatial relationships between the southern and northern tectophases.

Download or read book Subsurface Geology of a Prograding Carbonate Platform Margin Great Bahama Bank written by Robert N. Ginsburg and published by SEPM (Society for Sedimentary Geology). This book was released on 2001 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume will be of special interest to carbonate sedimentologists, geochemists, petroleum geologists, engineers, and seismologists. It addresses fundamental aspects of prograding carbonate platforms in a Neogene example from Great Bahama Bank. A remarkable seismic profile, which imaged the prograding margin, provided the seismic stratigraphic framework. Two continuouslycored and logged borings on the profile produced the ground truth for testing and characterizing processes: lithologies and ages of sequence boundaries; influence of sea level fluctuations on progradation, controls on impedance contrasts in carbonates; fluid flow through the submerged margin; log responses of different lithologies; and the origin, ages and depositional environments of the platform top and prograding clinothems. The new findings on diagenesis are of special interest, including complete mineral stabilization in seawater, early burial dolomitization related to sequence boundaries and how diagenesis controls sonic velocity and permeability.

Download or read book Lower Ordovician trilobites of the Kirtonryggen Formation Spitsbergen written by Richard A. Fortey and published by John Wiley & Sons. This book was released on 2013-10-22 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes early Ordovician (Ibexian: Tremadocian–early Floian) trilobites from Northern Spitsbergen from the section through the Kirtonryggen Formation adjacent to Hinlopen Strait. The Formation is divided into three Members, each with distinct trilobites collectively representing the fullest known succession from the Bathyurid biofacies of the eastern Laurentian carbonate platform. Previous research on the Ordovician of Spitsbergen is summarised and correlations with similar faunas previously described from Canada, Greenland, western Newfoundland, Vermont–New York State, Oklahoma and Missouri are discussed. Taxonomic problems are discussed in detail leading to the recognition of 53 species, of which 15 are new, belonging to 31 genera including four new. Twenty-four taxa are described under open or tentative nomenclature. The lower Member yields the earliest known occurrences of the Illaenoidea, Proetoidea and Scutelluoidea, supporting the hypotheses relating the origin of new major clades to inshore habitats.

Download or read book Compressional Tectonics written by Elizabeth J. Catlos and published by John Wiley & Sons. This book was released on 2023-05-04 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compressional Tectonics A synthesis of current knowledge on collisional and convergent plate boundaries worldwide Major mountain belts on Earth, such as the Alps, Himalayas, and Appalachians, have been built by compressional tectonic processes during continent-continent and arc-continent collisions. Understanding their formation and evolution is important because of the hazards associated with convergent and collisional plate boundaries, and because these mountain belts contain resources such as precious metals, rare earth elements, oil, gas, and coal. Compressional Tectonics: Plate Convergence to Mountain Building reviews our present-day knowledge of the tectonic evolution of the Alpine-Himalayan and Appalachian belts. Volume highlights include: Overview of terminology relating to compressional and contractional tectonics Discussion of subduction zone dynamics Debates over the timing of the collision and convergence of particular subduction and suture zones Examples of the different stages in the development of orogenic belts This book is one of a set of three in the collection Tectonic Processes: A Global View. The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Download or read book Caves and Karst of the Upper Midwest USA written by Greg A. Brick and published by Springer Nature. This book was released on 2020-12-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the karst and pseudokarst of the Upper Midwest, USA, consisting of the states of Minnesota, Wisconsin, Iowa, and Illinois—the first regional synthesis in 40 years. Starting with an overview of the regional geology of what is largely glaciated fluviokarst and paleokarst developed on Paleozoic carbonates, but including other lithologies such as the St. Peter Sandstone and the Ft. Dodge Gypsum, the caves, springs, sinkholes, and karst hydrogeology of each state are described. Special attention is devoted to the region’s longest caves: Coldwater Cave, Mystery Cave, and the Minnesota Cave Preserve caves. Application of tools such as data loggers and LiDAR, with new conceptual models such as hypogenic speleogenesis, has been transformative here. Special topics include lead and zinc mining in the Driftless Area, vertebrate and invertebrate cave fauna near the Laurentide ice limit, the impact and policies of nutrient and herbicide intensive modern agriculture on karst, and paleoclimate studies. The discovery, exploration, institutional history of caving organizations, and show caves of the Upper Midwest, from the year 1700 onwards, are brought up to date. The top 10 historical paradigms of cave and karst science in the Midwest are reviewed. Perspectives on paleontology, archeology, and Native American rock art are included.
