The Geological Record of Neoproterozoic Glaciations


Book Description

In recent years, interest in Neoproterozoic glaciations has grown as their pivotal role in Earth system evolution has become increasingly clear. One of the main goals of the IGCP Project number 512 was to produce a synthesis of newly available information on Neoproterozoic successions worldwide. This Memoir consists of a series of overview chapters followed by site-specific chapters. The overviews cover key topics including the history of research on Neoproterozoic glaciations, identification of glacial deposits, chemostratigraphic techniques and datasets, palaeomagnetism, biostratigraphy, geochronology and climate modelling. The site specific chapters include reviews of the history of research on these rocks and up-to-date syntheses of the structural framework, tectonic setting, palaeomagnetic & geochronological constraints, physical, biological, and chemical stratigraphy, and descriptions of the glaciogenic and associated strata, including economic deposits.




Earth History and Palaeogeography


Book Description

Using full-colour palaeogeographical maps from the Cambrian to the present, this interdisciplinary volume explains how plate motions and surface volcanism are linked to processes in the Earth's mantle, and to climate change and the evolution of the Earth's biota. These new and very detailed maps provide a complete and integrated Phanerozoic story of palaeogeography. They illustrate the development of all the major mountain-building orogenies. Old lands, seas, ice caps, volcanic regions, reefs, and coal beds are highlighted on the maps, as well as faunal and floral provinces. Many other original diagrams show sections from the Earth's core, through the mantle, and up to the lithosphere, and how Large Igneous Provinces are generated, helping to understand how plates have appeared, moved, and vanished through time. Supplementary resources are available online, making this an invaluable reference for researchers, graduate students, professional geoscientists and anyone interested in the geological history of the Earth.

Reconstruction of the Paleo-Asian Ocean


Book Description

This Proceedings volume contains selected papers from two symposia which were held during the 29th International Geological Congress, Kyoto, Japan, 24 August--3 September, 1992. The first symposium --- ''Reconstruction of the Paleo-Asian Ocean'' --- contains 11 papers from a group of scientists working together in an international project of the same name. The goal of the project is to collect and evaluate petrologic and tectonic data within specific terranes so as to understand the geodynamic processes leading to the amalgamation of Asia. These papers represent vital geological discussions for interpreting the geodynamic maps being produced by the project. From the second symposium of this volume --- ''Quaternary Environmental Change'' --- 14 papers were selected. The wide range of topics can be divided as follows: Deep sea core analysis; Coral reef and nearshore environment; Paleoenvironmental analysis; Tephras, Loess and Pedology; River morphology and others.




Earth History and Palaeogeography


Book Description

This book provides a complete Phanerozoic story of palaeogeography, using new and detailed full-colour maps, to link surface and deep-Earth processes.
