Book Synopsis A Window Into Terrestrial Paleoclimate by : Landon K. Burgener

Available in PDF, EPUB and Kindle. Book excerpt: The isotopic composition of pedogenic (formed in soil) carbonates provides a geologically abundant archive of terrestrial climate change and the interactions between Earth’s climate, geologic, and biologic systems. However, early paleoclimate reconstructions based on the carbon and oxygen isotope composition of soil carbonates were largely limited to qualitative estimates of change in key climate and environmental parameters such as surface temperature, precipitation, and soil biologic activity. The development of carbonate clumped isotope geothermometry has made it possible to make quantitative estimates of carbonate formation temperatures, and to relate those temperatures to changes in the Earth’s climate. The application of carbonate clumped isotope geothermometry to studies of soil carbonate systematics has shown that the seasonality of soil carbonate formation is closely linked to the timing of the local wet season, which has important implications for how the clumped isotope formation temperatures of soil carbonates relate to more meaningful climatologic parameters such as mean annual temperature. However, important questions remain regarding the impact of other climate and soil factors such as precipitation type (e.g., rain versus snow) and soil sediment grain size on the seasonality and mechanisms of soil carbonate formation. This dissertation places new constraints on the effects these soil and climate factors have on the seasonality of soil carbonate formation, sheds new light on non-equilibrium formation processes affecting soil carbonates in freezing environments, and provides new, quantitative terrestrial paleoclimate reconstructions of seasonal variability in surface temperature during the Late Cretaceous greenhouse period. Chapter 2 presents soil carbonate clumped and stable isotope data from an approximately 4000 m elevation transect on the western flank of the Chilean Andes. The results from this first chapter provide evidence that the presence or absence of a winter snowpack plays a critical role in modulating soil wetting and drying cycles, which in turn dictate the seasonality of soil carbonate formation. Additionally, this work provides the first evidence of soil carbonate formation under conditions of isotopic disequilibrium in freezing environments. Chapter 3 builds on the results of Chapter 2 by presenting the analyses of a suite of cold-climate soil carbonates from soils with both fine grained (the High Arctic and the Tibetan Plateau) and coarse grained (the Chilean and Argentinian Andes and the Dry Valleys, Antarctica) inter-cobble matrices. The findings of this chapter show that in freezing soils, matrix grain size is an important control on promoting or inhibiting kinetic isotope effects during soil carbonate formation. Soils with coarse-grained matrices experience rapid CO2 degassing associated with bicarbonate dehydration during soil freezing, which results in disequilibrium soil carbonate formation. In contrast, fine-grained matrices inhibit soil CO2 degassing and promote equilibrium carbonate formation, even in freezing environments. Chapter 4 represents and application of cutting-edge soil carbonate paleoclimate reconstruction techniques to the long-standing issue of terrestrial seasonal temperature variability during greenhouse climates. The clumped isotope composition of paleosol carbonates from Late Cretaceous sedimentary outcrops in south-central Utah and northwest Montana, USA are used to reconstruct summer soil temperatures along the mid-latitude, western margin of the Western Interior Seaway. These summer temperatures are then paired with previous reconstructions of local mean annual temperature to reconstruct mean annual range in temperature for these two sites. The results of this work show better agreement with model simulations of Late Cretaceous seasonal temperature changes than previous estimates, and add to a growing body of work that suggests that seasonal temperature variations in greenhouse environments did not differ significantly from the modern. These findings have important implications not only for our understanding of greenhouse climate, but also for the impact of climate on the paleogeographic distribution of ancient faunal communities.

Book Synopsis Constructing a High-resolution Record of Silurian Paleoclimate Using Carbonate Oxygen Isotopes by : Julia W. Clarke
Download or read book Constructing a High-resolution Record of Silurian Paleoclimate Using Carbonate Oxygen Isotopes written by Julia W. Clarke and published by . This book was released on 2021 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The collection of [delta]18O data from carbonates provides insight into the temperature of Earth millions of years ago. Paleozoic [delta]18O records are currently compiled from brachiopod fossils because of their resistance to diagenetic alteration, but this data is relatively sparse and not well time-resolved. Bulk carbonate [delta]18O data can present a more full view geographically and temporally, but is more susceptible to diagenesis. Here we overcome these challenges by using simple age models alongside previously collected [delta]18O data from [delta]13C studies to show that bulk carbonates can preserve a primary isotopic signal of Silurian temperatures, as well as generate a high-resolution climate record of the Silurian Period that correlates climate fluctuations with [delta]13C events. We then present [upper case delta]47-derived temperatures from clumped stable isotope analysis from four Silurian sites, and show that the reported temperatures can be consistent with the bulk rock [delta]18O record. With bulk carbonate [delta]18O measurements able to reconstruct an accurate record of Silurian temperatures, this generates an even larger dataset than the existing brachiopod compilation from E. Grossman and Joachimski (2020), and shows that this technique can be further applied to construct temperature records throughout the Paleozoic. Additionally, having a clear link between [delta]13C and temperature allows for a better understanding of carbon isotope excursions and their causes.

Book Synopsis Methods in Paleoecology by : Darin A. Croft
Download or read book Methods in Paleoecology written by Darin A. Croft and published by Springer. This book was released on 2018-10-27 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the reconstruction of past ecosystems and provides a comprehensive review of current techniques and their application in exemplar studies. The 18 chapters address a wide variety of topics that span vertebrate paleobiology and paleoecology (body mass, postcranial functional morphology, evolutionary dental morphology, microwear and mesowear, ecomorphology, mammal community structure analysis), contextual paleoenvironmental studies (paleosols and sedimentology, ichnofossils, pollen, phytoliths, plant macrofossils), and special techniques (bone microstructure, biomineral isotopes, inorganic isotopes, 3-D morphometrics, and ecometric modeling). A final chapter discusses how to integrate results of these studies with taphonomic data in order to more accurately characterize an ancient ecosystem. Current investigators, advanced undergraduates, and graduate students interested in the field of paleoecology will find this book immensely useful. The length and structure of the volume also makes it suitable for teaching a college-level course on reconstructing Cenozoic ecosystems.
Download or read book Calcretes written by V. Paul Wright and published by John Wiley & Sons. This book was released on 2009-04-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcretes are an important component of many ancient fluvial, lacustrine and shallow-marine carbonate sequences, and they are widely developed in many parts of the world at the present time. Calcretes are useful to the earth scientist involved in reconstructing ancient environments, palaeoclimates and palaeographics, and they may also reveal details of soil biota and chemistry. Over the last two decades the journal Sedimentology has published a number of articles on this subject and a compilation of them is presented here. In addition to the five main sections, this volume also includes an introduction to the subject that offers a review of recent work on calcretes. The collection of papers illustrates the range of calcrete occurrences and the great variety of textures and fabrics. This volume is authored and edited by experts and will serve as more than an introduction to the subject for geologists, soil scientists and geographers.

Book Synopsis Soils of the Past by : Gregory J. Retallack
Download or read book Soils of the Past written by Gregory J. Retallack and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscapes viewed from afar have a timeless quality that is soothing to the human spirit. Yet a tranquil wilderness scene is but a snapshot in the steady stream of surficial change. Wind, water and human activities reshape the landscape by means of gradual to catastrophic and usually irreversible events. Much of this change destroys past landscapes, but at some times and places, landscapes are buried in the rock record. This work is dedicated to the discovery of past landscapes and their life through the fossil record of soils. A long history of surficial changes extending back almost to the origin of our planet can be deciphered from the study of these buried soils, or paleosols. Some rudiments of this history, and our place in it, are outlined in a final section of this book. But first it is necessary to learn something of the language of soils, of what happens to them when buried in the rock record and which of the forces of nature can be confidently reconstructed from their remains. Much of this preliminary material is borrowed from soil science, but throughout emphasis is laid on features that provide most reliable evidence of landscapes during the distant geological past. This book has evolved primarily as a text for senior level university courses in paleopedology: the study of fossil soils.
Book Synopsis Devonian Climate, Sea Level and Evolutionary Events by : R. T. Becker, 1st
Download or read book Devonian Climate, Sea Level and Evolutionary Events written by R. T. Becker, 1st and published by Geological Society of London. This book was released on 2016-10-20 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.
