Cretaceous-Tertiary High-Latitude Palaeoenvironments: James Ross Basin, Antarctica - Special Publication no. 258 (Geological Society Special Publication)

High-latitude settings are sensitive to climatically driven palaeoenvironmental change and the resultant biotic response. Climate change through the peak interval of Cretaceous warmth, Late Cretaceous cooling, onset and expansion of the Antarctic ice sheet, and subsequently the variability of Neogene glaciation, are all recorded within the sedimentary and volcanic successions exposed within the James Ross Basin, Antarctica. This site provides the longest onshore record of Cretaceous-Tertiary sedimentary and volcanic rocks in Antarctica and is a key reference section for Cretaceous-Tertiary global change. The sedimentary succession is richly fossiliferous, yielding diverse invertebrate, vertebrate and plant fossil assemblages, allowing the reconstruction of both terrestrial and marine systems. The papers within this volume provide an overview of recent advances in the understanding of palaeoenvironmental change spanning the mid-Cretaceous to the Neogene of the James Ross Basin and related biotic change, and will be of interest to many working on Cretaceous and Tertiary palaeoenvironmental change.Also available: The Neuquen Basin, Argentina: A Case Study in Sequence Stratigraphy and Basin Dynamics - ISBN 1862391904 Terrane Processes at the Margins of Gondwana - ISBN 1862391793The Palynology And Micropalaeontology of Boundaries - ISBN 1862391602 The Neuquén Basin : An Overview / John A.

The Australide orogen, the southern hemisphere Neoproterozoic to Mesozoic terrane accretionary orogen that forms the palaeo-Pacific margin of Gondwana, is one of the largest and longest-lived orogens on Earth. This book brings together a series of reviews and multidisciplinary research papers that comprehensively cover the Australides from the Tasman orogen of eastern Australia to the Neoproterozoic and Palaeozoic orogens of South America, taking in New Zealand and Antarctica along the way. It deals with the evolution of the southern Gondwana margin, as it grew during a series of terrane accretion episodes from the late Proterozoic through to final fragmentation in mid-Cretaceous times. global perspectives are given by comparison with the Palaeozoic northern Gondwana margin and documentation of world-wide terrane accretion episodes in the Late Triassic-Early Jurassic and mid-Cretaceous. The Tasmanides of eastern Australia, and the terrane histories of New Zealand and souther South America are given comprehensive up-to-date reviews

this Volume Explores Geological Boundaries In Time And Space Using Palynology And Micropalaeontology. Boundaries Produce Distinct Signatures In The Micropalaeontological Record. Diffuse Or Sharp, Gradual Or Abrupt, Boundaries Can Tell Us Much About The Response Of Biotic Systems To Environmental Change In Both Marine And Terrestrial Realms. Different Microfossil Groups And Geological Contexts Require Their Own Approaches, Definitions And Considerations Of Boundaries. The Papers In This Compilation Capture The Current Range Of Thinking On The Methodology Of Boundary Identification From Biostratigraphical, Ecological And Palaeoenvironmental Perspectives. Contributions Span The Cambrian To Miocene And Feature Many Fossil Groups (including Pollen, Dinoflagellates, Foraminifera, Ostracodes, Conodonts And Diatoms). With A Strong Canadian And North American Focus, The Volume Also Includes Contributions From Poland, Egypt, Belgium, Argentina And The United Kingdom.

The Neuquén Basin of northern Patagonia is one of the largest petroleum provinces in South America and includes a dramatic record of relative sea-level changes as well as a unique and globally important palaeontological record. Understanding this region is also central to unravelling the history of the Andes. The latest developments in the study of the area have been combined in this volume to give an integrated series of case studies that document the structural, igneous, sedimentological and palaeontological history of the region from the Triassic to the Recent This volume explores geological boundaries in time and space using palynology and micropalaeontology. Boundaries produce distinct signatures in the micropalaeontological record. They can tell us much about the response of biotic systems to environmental change in both marine and terrestrial realms. Different microfossil groups and geological contexts require their own approaches, definitions and considerations of boundaries. The papers here cover the methodology of boundary identification from biostratigraphical, ecological and palaeoenvironmental perspectives Includes papers presented at a session sponsored by the Canadian Association of Palynologists, which was held at the Geological Association of Canada-Mineralogical Association of Canada Joint Annual Meeting in Saskatoon, 2002.
