Book Synopsis Re-evaluating the Late Devonian Mass Extinction by : Kelly N. Hillbun
Download or read book Re-evaluating the Late Devonian Mass Extinction written by Kelly N. Hillbun and published by . This book was released on 2015 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goal of this dissertation is to increase understanding of the so-called Late Devonian mass extinction through the use of stable isotope geochemistry. Despite decades of research, the timing, cause(s), and extent of the events surrounding this devastating interval in Earth history remain poorly understood. One of the best places to study the Devonian period is the Lennard Shelf in the Canning Basin of Western Australia. This region contains extensive, well-preserved exposures of Middle and Upper Devonian (Givetian, Frasnian, and Famennian) carbonate reefal platforms and slopes that are ideal for geochemical analyses. A significant amount of information could be learned about the Late Devonian mass extinction in the Canning Basin if we had a detailed chronostratigraphic framework of platform to basin strata and a better understanding of the paleoenvironmental conditions during the Upper Devonian. This research aims to use stable isotope chemostratigraphy to help build a high resolution chronostratigraphy and examine any environmental changes leading up to and following the F-F boundary that may have contributed to Devonian extinction events in the Canning Basin. This dissertation is divided into two parts; the first concerns my research on the Late Devonian mass extinction while the second is ancillary and documents my astrobiology research rotation. Part 1 contains introductory and concluding remarks as well as three chapters written as scientific manuscripts that have been, or will soon be, submitted for journal publication. The first of these three chapters examines the local and global controls on carbon isotope chemostratigraphy in the Lennard Shelf system to validate the use of secular variations as a chronostratigraphic tool for regional and global correlations. The next chapter provides a detailed, expanded view of the F-F boundary and constrains the pattern of carbon isotope perturbations across said boundary at the intra-zonal scale. The third scientific chapter broadens focus from the F-F to the entirely of the Upper Devonian and presents the first carbon isotope composite curve from Western Australia that is used to test the global nature (timing and extent) of Late Devonian events and examine the relationship between carbon isotope fluctuations, faunal turnover, and changes in the paleoenvironment (sea level, climate, ocean chemistry, paleogeography). Results from Part 1 not only have implications for re-evaluating one of the "Big Five" mass extinctions in the Phanerozoic, but are also relevant to studies in astrobiology and have additional applications in the oil and gas industry. The final chapter of my dissertation, which is in Part 2, concerns interdisciplinary, astrobiology work done during summer quarter, 2014, that was devoted to analyzing the relationship between astronomy and geology circa 1770-1810. This chapter is included in my dissertation as partial fulfillment of my dual-title astrobiology degree.

Book Synopsis Carbon Isotope Stratigraphy of the Devonian (emsian-eifelian) Onondaga Formation, New York State by : Lisa Catherine Fay
Download or read book Carbon Isotope Stratigraphy of the Devonian (emsian-eifelian) Onondaga Formation, New York State written by Lisa Catherine Fay and published by . This book was released on 2006 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Carbon isotope ([delta]3Ccarb) values were determined from carbonate deposits in the Onondaga Formation of the Appalachian foreland basin to correlate the Early-Middle Devonian (Emsian-Eifelian) strata of New York with a global stratigraphic framework. [delta]13C[carb] values representing the lower part of the Onondaga (Edgecliff Member) were sampled at the Neid Road quarry near the town of LeRoy, eastern New York, and values through the entire Onondaga (Edgecliff-Seneca Members) were obtained from a New York State Geological Survey drill core from the central Finger Lakes region of New York. New York [delta]13C[carb] values are compared to values from the central and southern European sections of Buggisch and Mann (2004) and van Geldern et al. (in press). The [delta]13C[carb] trend through the late Polygnathus costatuspatulus-early Polygnathus costatus partitus zones in the Neid Road quarry section is relatively steady about 1.4 %o, which agrees with European values of this time interval (Buggisch and Mann, 2004). Data from the drill core also show the steady values observed at the quarry, followed by a well defined 3.0 %o decrease in [delta]13C[carb] through the Polygnathus costatus costatus zone. In contrast to the relatively pure limestones of the Onondaga, the overlying unit in the drill core (Union Springs Formation of the Hamilton Group) consists of dark, organic rich, argillaceous limestones to calcareous mudstones, with dark shaly interbeds. The occurrence of organic rich strata coincident with a decrease in [delta]13C[carb], values can be explained by changes in depth of the local pycnocline, which may be caused by upwelling of nutrient rich deep water into shallower settings, depositing fine organic rich material while simultaneously inundating surface waters with 12C, thus, shifting the [delta]13C[carb] baseline to lighter values.

Book Synopsis Devonian Events and Correlations by : R. T. Becker
Download or read book Devonian Events and Correlations written by R. T. Becker and published by Geological Society of London. This book was released on 2007 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Devonian was a peculiar period, characterized by simplified plate tectonic configurations, climatic overheating and widely flooded continents. The bloom of fishes and ammonoids, extensive reef complexes, and the conquest of land indicate major biosphere innovations, punctuated by many global events, including two of the biggest mass extinctions. The Devonian was the first system for which subdivisions were formally defined. This was achieved by significant advances in pelagic biostratigraphy. The chronostratigraphic framework and interdisciplinary techniques allow us to correlate intervals or sudden events across facies boundaries, in order to reconstruct the sedimentary and evolutionary history of the system with highest precision. This volume honors the lifetime stratigraphic achievements of Michael Robert House (1930-2002). Based on case studies from Europe, North Africa and North America, it shows how the combination of biostratigraphy, chemostratigraphy, magnetostratigraphy, sequence stratigraphy and event stratigraphy can contribute to a much deeper understanding of both regional and global environmental change.

Book Synopsis Stratigraphic Paleobiology by : Mark E. Patzkowsky
Download or read book Stratigraphic Paleobiology written by Mark E. Patzkowsky and published by University of Chicago Press. This book was released on 2012-03-12 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether the fossil record should be read at face value or whether it presents a distorted view of the history of life is an argument seemingly as old as many fossils themselves. In the late 1700s, Georges Cuvier argued for a literal interpretation, but in the early 1800s, Charles Lyell’s gradualist view of the earth’s history required a more nuanced interpretation of that same record. To this day, the tension between literal and interpretive readings lies at the heart of paleontological research, influencing the way scientists view extinction patterns and their causes, ecosystem persistence and turnover, and the pattern of morphologic change and mode of speciation. With Stratigraphic Paleobiology, Mark E. Patzkowsky and Steven M. Holland present a critical framework for assessing the fossil record, one based on a modern understanding of the principles of sediment accumulation. Patzkowsky and Holland argue that the distribution of fossil taxa in time and space is controlled not only by processes of ecology, evolution, and environmental change, but also by the stratigraphic processes that govern where and when sediment that might contain fossils is deposited and preserved. The authors explore the exciting possibilities of stratigraphic paleobiology, and along the way demonstrate its great potential to answer some of the most critical questions about the history of life: How and why do environmental niches change over time? What is the tempo and mode of evolutionary change and what processes drive this change? How has the diversity of life changed through time, and what processes control this change? And, finally, what is the tempo and mode of change in ecosystems over time?
