Summarizes invited and contributed papers from the May 1992 Project pangea workshop in Lawrence, Kansas. Topics include the climatic evolution of India and Australia, pangean orogenic and epeirogenic uplifts, permian climatic cooling in the Canadian Arctic, and pangean shelf carbonates. Annotation c
In recent years, efforts to integrate solid earth geophysical studies and climate studies have progressed slowly, but this volume responds to the deficiency with an in-depth examination of climate modeling. Written by eminent figures from both disciplines, it focuses on the role of tectonic boundary conditions for paleoclimate reconstruction at the same time it presents background material on the impact of tectonic changes on climate and the uncertainties in tectonic boundary conditions.
Explores soil as a nexus for water, chemicals, and biologically coupled nutrient cycling Soil is a narrow but critically important zone on Earth's surface. It is the interface for water and carbon recycling from above and part of the cycling of sediment and rock from below. Hydrogeology, Chemical Weathering, and Soil Formation places chemical weathering and soil formation in its geological, climatological, biological and hydrological perspective. Volume highlights include: The evolution of soils over 3.25 billion years Basic processes contributing to soil formation How chemical weathering and soil formation relate to water and energy fluxes The role of pedogenesis in geomorphology Relationships between climate soils and biota Soils, aeolian deposits, and crusts as geologic dating tools Impacts of land-use change on soils The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the Editors
Ancient ice ages are revealed by distinctive stratal facies that tell us much about the times of coolness and how the climate system works. Several strong ice ages were recorded in the late Paleozic time and during transitions from the Devonian in to the Carboniferous and from the Ordovician in to the Silurian. In Precambrian time, several are documented for both the late and early Proterozoic age. This title explores findings on the pre-Mesozoic ice ages, examining climate in relation to tectonobiogeochemical activities rooted in the changing earth-air-ocean system.
The breakup of the Pangean supercontinent in the Triassic-Jurassic age left great rift basins containing an extraordinary record of the physical and biological conditions which precipitated a major extinction event at the time. These basins collectively form a rift province called the Central Atlantic Margin, which spans more than 45 degrees of paleolatitude and records over 35 million years of Earth history. Leading experts present a detailed review of the rift province's geology, paleobiology, and geophysics. This extensive two-volume work offers in-depth coverage of the North American components of the Central Atlantic Magmatic Province. In volume 1, leading researchers give thorough reviews and highlight recent advances in our understanding of the structural geology, tectonics, and volcanism of the Central Atlantic Magmatic Province.
Dr James Maxlow's new eBook, Terra Non Firma Earth, deals with one of the most controversial scientific theories about the Earth. It is commonly believed that the Earth has been a constant diameter during most of geological time, but James Maxlow provides a range of evidence that the Earth is expanding in size. James Maxlow's eBook is an important landmark in science and the questions raised in it need to be seriously considered by all sincere scientists.
This volume, in honour of Peter L. Forey, is about fishes as palaeobiogeographic indicators in the Mesozoic and Cenozoic. The last 250 million years in the history of Earth have witnessed the break-up of Pangaea, affecting the biogeography of organisms. Fishes occupy almost all freshwater and marine environments, making them a good tool to assess palaeogeographic models. The volume begins with studies of Triassic chondrichthyans and lungfishes, with reflections on Triassic palaeogeography. Phylogeny and distribution of Late Jurassic neoselachians and basal teleosts are broached, and are followed by five papers about the Cretaceous, dealing with SE Asian sharks, South American ray-finned fishes and coelacanths, European characiforms, and global fish palaeogeography. Then six papers cover Tertiary subjects, such as bony tongues, eels, cypriniforms and coelacanths. There is generally a good fit between fish phylogenies and the evolution of the palaeogeographical pattern, although a few discrepancies question details of current palaeogeographic models and/or some aspects of fish phylogeny.
The earth's pre-Quaternary period--more than two million years ago--has been studied systematically only since the 1960's, when geologists started to take seriously the concept that the continents have changed position on the earth's surface. While previous books have dealt with climate models and paleoclimate, this is the first to offer a sustained exploration of the methods that are the foundation of any interpretation of earth processes.
"This volume presents current understanding of the mechanisms and environments of the formation of calcretes and palustrine carbonates. Through a series of specific field examples, papers in this volume illustrate the wide variety of potential applications of these types of deposits. The papers presented here cover a wide array of ages and environmental settings of calcrete and palustrine deposition and include many interesting applications, such as the climatic and geomorphic controls on calcrete formation, possible modern analogues for palustrine carbonates, the interplay between palustrine, pedogenic, and diagenetic processes, the utility of radio-isotopic methods for dating pedogenic carbonates, applications to understanding landscape evolution, and reconstruction of diagenetic sequences. The result is a state-of-the-art book on these deposits so common in the geological record and in recent environments."--Publisher's website.
