Download or read book The Lewisian written by Graham Park and published by Liverpool University Press. This book was released on 2022-05-01 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first 2,500 million years of the geological history of Britain are stored in the gneisses of the Lewisian Complex of NW Scotland. Graham Park explores the long journey of discovery in which this history was gradually deciphered and the controversies and arguments in the scientific community over the past two centuries that arose in this period.

Download or read book Large Igneous Provinces from Gondwana and Adjacent Regions written by S. Sensarma and published by Geological Society of London. This book was released on 2018-02-19 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gondwana, comprising more than 64% of the present day continental mass, is home to 33% of large igneous provinces (LIPs) and key to understanding the lithosphere–atmosphere system and related tectonics that influenced global climate and sediment production on Earth. Gondwana has many of the largest LIPs, with areas of 200 000 to 2 000 000 km2. Several Gondwana LIPs erupted near active continental margins as well as within continents. The rifting of continents continued even after LIP emplacement or was aborted by a coeval compression and did not open into an ocean. Important contemporary frontiers include understanding significant amounts of synchronous silicic volcanic rocks in mafic LIPs, bringing better stratigraphic constraints supported by precise age dating and volume estimation of LIPs, the possible link between LIP emplacement and biotic crisis, refinement of the existing petrogenetic models and assessing large eruptions and associated societal risk. This volume covers topics on magma emplacements, petrology and geochemistry, source characteristics, flood basalt–carbonatite linkage, tectonics and geochronology of LIPs distributed in Gondwana continents.

Download or read book The Geology of Antarctica written by Robert J. Tingey and published by Oxford University Press, USA. This book was released on 1991 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological information from Antarctica has so far been published in expedition reports, conference proceedings, and science journals. This information is thus not readily accessible to Earth scientists who are interested, but not directly involved, in Antarctic research. The Geology ofAntarctica bridges this gap with each chapter presenting an authoritative review of a particular aspect of Antarctic geology. The text provides descriptions of all major rock units found in Antarctica, as well as reviews of Antarctic palaeontology, geophysics, petroleum prospects, and mineral resources. Special attention is drawn to the features of Antarctica that are significant from the wider perspectives of globalgeology.

Download or read book Lamprophyres Lamproites and Related Rocks written by L. Krmíček and published by Geological Society of London. This book was released on 2022-02-09 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleoproterozoic to Cenozoic lamprophyres, lamproites and related rock types (e.g., orangeites, kimberlites) are volatile-rich mafic magmatic rocks with a unique potential for the investigation of processes affecting mantle reservoirs. They originated from primary mantle-derived melts that intruded both cratons and off-craton regions, which were parts of former supercontinents – Columbia, Rodinia and Gondwana–Pangea. Well-known for hosting economic minerals and elements such as diamonds, base metals, gold and platinum-group elements, they are also significant for our understanding of deep-mantle processes, such as mantle metasomatism and mantle plume–lithosphere interactions, as well as large-scale geodynamic processes, such as subduction-related tectonics, and supercontinent amalgamation and break-up. This book aims to provide a timely overview of the state-of-the-art and recent advances as achieved by various research groups around the world. Mineralogical, geochemical, geochronological and isotope analyses are used to decipher the complex petrogenesis and metallogenesis of these extraordinary rocks, and unravel a complete history of tectonic events related to individual supercontinent cycles.
