Richard E. Ernst – författare

The Archean Earth: Tempos and Events, Second Edition is a process-based reference book that focuses on the most important events in early Earth, bringing together experts across Earth Sciences to give a comprehensive overview of the main events of the Archean Eon, as well as of the rates at which important geological and geobiological processes occurred in the same time interval. Over the last two decades, significant progress has been made in our understanding of the processes and events on the early Earth corresponding to advances in the analytical technologies and the continuing efforts of many colleagues that pursue their passion of unravelling the Archean rock record.The book addresses the origin of the Earth, succeeding impact events, and the evolution of the early Earth, covering topics such as Archean tectonics, volcanism, generation of continental crust, and the ongoing debate about the onset of plate tectonics; the evolution and models for Earth's hydrosphere and atmosphere; the Archean atmosphere and chemical sedimentation; and sedimentation through Archean time; among others. Each topic is well-illustrated and includes a closing commentary at the end of each chapter, leading up to the final chapter which blends the major geological events and rates at which important processes occurred into a synthesis, postulating a number of "event clusters" in the Archean when significant changes occurred in many natural systems and geological environments

Provides a comprehensive introduction and overview on early Earth, highlighting the Archean Eon in the context of the larger time scalesPresents detailed descriptions of the main processes, events, and rates that occurred throughout the ArcheanOffers an assessment of the first habitable environments, the preserved morphological and geochemical traces of early life, and the impact it had on Earth's biogeochemical cycles

Large igneous provinces (LIPs) are intraplate magmatic events, involving volumes of mainly mafic magma upwards of 100,000 km3, and often above 1 million km3. They are linked to continental break-up, global environmental catastrophes, regional uplift and a variety of ore deposit types. In this up-to-date, fascinating book, leading expert Richard E. Ernst explores all aspects of LIPs, beginning by introducing their definition and essential characteristics. Topics covered include continental and oceanic LIPs; their origins, structures, and geochemistry; geological and environmental effects; association with silicic, carbonatite and kimberlite magmatism; and analogues of LIPs in the Archean, and on other planets. The book concludes with an assessment of LIPs' influence on natural resources such as mineral deposits, petroleum and aquifers. This is a one-stop resource for researchers and graduate students in a wide range of disciplines, including tectonics, igneous petrology, geochemistry, geophysics, Earth history, and planetary geology, and for mining industry professionals.

Environmental changes caused by LIPs and SLIPs include rapid global warming, global cooling ('Snowball Earth'), oceanic anoxia events, mercury poisoning, atmospheric and oceanic acidification, and sea level changes.Continued research to characterize the effects of these extremely large and typically short duration igneous events on atmospheric and oceanic chemistry through Earth history can provide lessons for understanding and mitigating modern climate change.Large Igneous Provinces: A Driver of Global Environmental and Biotic Changes describes the interactions between the effects of LIPs and other drivers of climatic change, the limits of the LIP effect, and the atmospheric and oceanic consequences of LIPs in significant environmental events.Volume highlights include: Temporal record of large igneous provinces (LIPs)Environmental impacts of LIP emplacementPrecambrian, Proterozoic, and Phanerozoic case historiesLinks between geochemical proxies and the LIP recordAlternative causes for environmental changeKey parameters related to LIPs and SLIPs for use in environmental change modellingRole of LIPs in Permo-Triassic, Triassic-Jurassic, and other mass extinction eventsThe American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.
