Download or read book Rock Magnetic Cyclostratigraphy written by Kenneth P. Kodama and published by John Wiley & Sons. This book was released on 2014-10-06 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rock magnetic cyclostratigraphy merges environmental magnetism, in which rock magnetic measurements are used to detect past environmental change, and cyclostratigraphy, in which cyclic variations of lithology or a sedimentary rock’s physical properties are related to astronomically-forced paleoclimate change. In addition to providing paleoclimate data, cyclostratigraphy can establish high-resolution chronostratigraphy for a sequence of sedimentary rocks, even at distant times in Earth’s history. This book provides an overview of concepts underlying these two techniques, recipes for the time series analysis of cyclostratigraphy, and case studies to illustrate the variety and breadth of problems addressed by rock magnetic cyclostratigraphy. New Analytical Methods in Earth and Environmental Science Because of the plethora of analytical techniques now available, and the acceleration of technological advance, many earth scientists find it difficult to know where to turn for reliable information on the latest tools at their disposal, and may lack the expertise to assess the relative strengths or limitations of a particular technique. This new series will address these difficulties by providing accessible introductions to important new techniques, lab and field protocols, suggestions for data handling and interpretation, and useful case studies. The series represents an invaluable and trusted source of information for researchers, advanced students and applied earth scientists wishing to familiarise themselves with emerging techniques in their field. All titles in this series are available in a variety of full-colour, searchable e-book formats.

Download or read book The Geology of Stratigraphic Sequences written by Andrew D. Miall and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequence stratigraphy represents a new paradigm in geology. The principal hypothesis is that stratigraphie successions may be subdivided into discrete sequences bounded by widespread unconformities. There are two parts to this hypothesis. First, it suggests that the driving forces which generate sequences and their bounding unconformities also generate predietable three-dimensional stratigraphies. In re cent years stratigraphie research guided by sequence models has brought about fundamental im provements in our understanding of stratigraphie processes and the controls of basin architecture. Sequence models have provided a powerful framework for mapping and numerieal modeling, enabling the science of stratigraphy to advance with rapid strides. This research has demonstrated the importance of a wide range of processes for the generation of cyclie sequences, including eustasy, tectonics, and orbital forcing of climate change. The main objective of this book is to document the sequence record and to discuss our current state of knowledge about sequence-generating processes.

Download or read book Orbital Forcing Timescales and Cyclostratigraphy written by Michael Robert House and published by Geological Society Publishing House. This book was released on 1995 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The metronomic variations of the Earth-Moon system and of the Earth-Sun orbital patterns produce gravitational and temperature effects that alter the physical environment on the Earth's surface. These give an interpenetrating effect of forcing cycles ranging from twice-daily tides, day-night alternations, various tidal patterns and the annual solar pattern. All of these have been used palaeontologically to give precision to short-term age determination in the past. It is cycles of the Milankovitch band that are showing promise of enabling new practical timescales to be established for parts of the geological record. These depend on changes in the Earth-Sun distance and changes in the tilt of the Earth's axis with respect to the Earth's orbit round the Sun. There is increasing evidence that small-scale sedimentary rhythmic couplets may represent the effect of such changes. The disentangling of the interpenetrating cycles to produce an orbital forcing timescale is an exciting problem and challenge for palaeobiology and sedimentology. These should enable numerical dates to be given to bio- and chronostratigraphical timescales and eventually enable many Earth processes to be analysed in real time. The papers in this volume represent major new developments in sedimentological, paIaeontological, geochemical and stratigraphical research being undertaken in this field.--Provided by publisher.--Provided by publisher.

Download or read book Antarctic Ice Sheet History Neogene Cyclostratigraphy and Quantitative Biostratigraphy in the Southern Ocean written by Nicholas Benetti Sullivan and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of deep time is crucial for contextualizing present and future environmental change. This is particularly true for the high southern latitudes, a linchpin of the global climate system. However, assembling and compositing a complete, high-resolution sedimentary archive in these regions is often difficult, owing to a range of logistical, environmental, and stratigraphic challenges. Two quantitative methodologies are brought to bear on these problems. The first is stratigraphic constrained optimization (CONOP), a tool for compiling individual, imperfect, local stratigraphic sections into a parsimonious composite succession. The second is astrochronology, a branch of cyclostratigraphy focused on the recognition of astronomically influenced climate rhythms (Milankovitch Cycles) in the stratigraphic record. The findings presented here, using these approaches, provide insight into past environmental and oceanographic change occurring at timescales ranging from millennia to millions of years. Chapter 1 of this dissertation presents strategies for calibrating timescales generated by CONOP with the geochronological information encoded in astrochronology. A synthesis of new and published cyclostratigraphic records in the Southern Ocean are reviewed. These are then used to help refine and calibrate a CONOP output, and four strategies for integrating these interpretations are discussed. Various case studies are used to build a refined composite history for the Southern Ocean. Chapter 2 presents a new Early Miocene cyclostratigraphic analysis of Miocene strata at two ice-proximal sites, IODP U1521 and AND-2A, in the Ross Sea in the Southern Ocean. Astrochronological analysis was conducted on clast abundance data that reflect the proportion of ice-rafted debris. The variable strength of observed obliquity and eccentricity forcing in data across two distinct time intervals (17.4-17.7 Ma and 18.0-18.5 Ma) informs our uncertainty of ice sheet dynamics during the warm climate of the Miocene and helps characterize the different responses of marine influenced versus terrestrial-based ice sheets. These interpretations are then used to inform and develop a new hypothesis relating the evolution of the Antarctic cryosphere to multi-million year "grand cycles" in eccentricity and obliquity. Finally, chapter 3 presents the discovery of astronomically-influenced millennial (1-15 kyr) cycles in early Miocene strata in the core AND-2A from McMurdo Sound. This discovery shows the ubiquity of millennial-scale cyclicity in the southern cryosphere, even during the comparatively warmer Miocene climates that predate a large Northern Hemisphere ice sheet. These findings help us understand the intrinsic behavior of the Antarctic ice sheet and its response to external forcing at a range of temporal scales. The chapters of this dissertation contribute to a better understanding of the temporal dynamics of the Southern Ocean and the Antarctic cryosphere, a complex and dynamic system that may respond to modern climate change in unexpected ways. This has been achieved with the development of new ways of using astrochronology and CONOP together, a methodological advancement that shows promise for application at all levels of the geologic timescale.

Download or read book Magnetic Susceptibility Application written by A.C. Da Silva and published by Geological Society of London. This book was released on 2015-10-14 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic susceptibility (MS) is a tool frequently used by geologists on sediments or rocks to perform correlations and sea-level or climatic reconstructions. Applied measurements are made on unoriented, bulk samples and bulk MS is mostly influenced by the magnetic mineral content of the rock and often interpreted as influenced by detrital inputs. Magnetic data acquisition is fast and straightforward and this allows the high-resolution sampling needed for palaeoclimatic research (e.g. spectral analysis). However, the link with detrital inputs is not always preserved and the impact of diagenesis on the final MS signal can blur primary information. This volume includes contributions dealing with the origin of the magnetic minerals, and the application of MS as a palaeoenvironmental or palaeoclimatic proxy and also as a tool to provide astronomical calibration in order to improve the chronology of selected time intervals.

Download or read book Cyclostratigraphy and the Milankovitch Theory written by W. Schwarzacher and published by Elsevier. This book was released on 1993-08-24 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclostratigraphy is concerned primarily with measuring geological time and the time units used in this approach are sedimentary cycles. Milankovitch cycles mark time intervals of tens of thousands to several millions of years. Such cycles are the result of variations in the Earth's position in relation to the Sun and these in turn determine the climatic variations. The Milankovitch theory was resurrected in the 1960's when evidence from Pleistocene deep sea sediments linked orbital variations and climate. This monograph discusses sedimentary cycles and their use in measuring geologic time. There is considerable effort made to clarify the term "sedimentary cycle", in particular, the two opposing concepts of cyclic stratification and event stratification. The recognition of sedimentary cycles and of Milankovitch cycles specifically, is considered and care is taken with the question of relating sediment thickness to time. Several examples from the Carboniferous to the Cretaceous are given to show how cyclostratigraphy can be applied to current geological problems. This volume should be of interest to geologists involved with stratigraphical analysis and basin analysis.
