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 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.

This book was released on 2014 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stratigraphic architecture and evolution of the Late Cambrian-Early Ordovician Owen Group isdocumented in this research project. An integrated approach was used to ascertain the basin evolution,with emphasis on the stratigraphic build-up of the Owen Group in the Mts Jukes-Darwin-Sorell-Strahan area of the southern West Coast Range, Tasmania, Australia. This included field mapping,measurement of detailed stratigraphic sections, sedimentary facies analysis, petrography, and Scanning Electron Microscopy, along with Energy Dispersive X-ray Spectroscopy and geochemical analyses. The thesis presents an overall source to sink understanding from regional to micro-nano scale processes involved in the deposition, stratigraphic build-up and diagenesis of the Owen Group.The depositional settings during the Late Cambrian-Early Ordovician were markedly different fromtheir present day analogues, and the Owen Group sediments provide excellent exposures to facilitate a study of pre-vegetation, warm, humid climate, braided fluvial depositional settings. In the area studied the group is comprised of conglomerate, sandstone and minor mudstone successions that are markedly different compared to other areas in western and northern Tasmania. The sediments were deposited in half-grabens formed during Late Cambrian extensional tectonics, with each depocenter containing a unique stratigraphy reflecting different depositional styles. The most remarkable feature of the Jukes-Darwin area stratigraphy is the occurrence of two, fining up, alluvial-marine cycles, separated by an unconformity. The new, two fold classification presented here divides the siliciclastics into lower and upper sequences. The overall stratigraphy is subdivided into 17 informal mappable units, 13 units (L1-L13) in the lower sequence and 4 units (U1-U4) in the upper sequence.Each sequence begins with sediments deposited in a braided fluvial system and ends with sediments deposited in an intertidal to shallow marine environment. However, in the Mt Sorell-Mt Strahan depocenter the Owen Group is comprised only of a thick, monotonous, conglomerate-dominated sequence deposited by sheet flow processes.The sediments are mainly comprised of quartz, mica, lithic grains (volcanic, metamorphic andsedimentary), clays, zircon, tourmaline, leucoxene, rutile, glauconite and chert grains. These were supplied by a Proterozoic Tyennan metamorphic and a Middle Cambrian Mount Read Volcanicprovenance and have undergone severe diagenesis, including quartz overgrowth, iron coating, andhaematite, chlorite and sericite alteration. Multi-phase haematite-related diagenesis is common and late stage hydrothermal fluid alteration assemblages have severely altered and coloured the sediments.Geochemical analyses of the Owen Group show that the average composition of sandstones includesvery high SiO2 (92.72%), low Al2O3 (3.34%) and Fe2O3 (1.71%), very low K2O (0.90%) and MgO(0.15%), while CaO and Na2O are extremely low (

Available in PDF, EPUB and Kindle. Book excerpt: A new data set of 53 $\sp{87}$Sr/$\sp{86}$Sr ratios for the Lower Devonian has been collected from well preserved, and stratigraphically well constrained, brachiopod shells from the Leon region in Spain, western Urals in Russia, Podolia in Ukraine and New York State in the United States. Multiple criteria, including trace element and stable isotope (C, O) analysis, scanning electron microscopy, cathodoluminescence and optical light microscopy, were used to determine the state of preservation of the samples.
