Download or read book Volcanism in Antarctica: 200 Million Years of Subduction, Rifting and Continental Break-up written by J.L. Smellie and published by Geological Society of London. This book was released on 2021-06-09 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memoir is the first to review all of Antarctica’s volcanism between 200 million years ago and the Present. The region is still volcanically active. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. Each is described in terms of (1) the volcanology and eruptive palaeoenvironments; (2) petrology and origin of magma; and (3) active volcanism, including tephrochronology. Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana; the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin; Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation; numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world’s major zones of lithospheric extension (the West Antarctic Rift System); and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg).
Book Synopsis Alkaline Rocks and Carbonatites of the World, Part 4 by : A.R. Woolley
Download or read book Alkaline Rocks and Carbonatites of the World, Part 4 written by A.R. Woolley and published by Geological Society of London. This book was released on 2019-09-02 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alkaline igneous rocks and carbonatites are compositionally and mineralogically the most diverse of all igneous rocks and, apart from their scientific interest, are of major, and growing, economic importance. They are important repositories of certain metals and commodities, indeed the only significant sources of some of them, and include Nb, the rare earths, Cu, V, diamond, phosphate, vermiculite, bauxite, raw materials for the manufacture of ceramics, and potentially Th and U. The economic potential of these rocks is now widely appreciated, particularly since the commencement of the mining of the Palabora carbonatite for copper and a host of valuable by-products. Similarly, the crucial economic dominance of rare earth production from carbonatite-related occurrences in China, has stimulated the world-wide hunt for similar deposits. This volume describes and provides ready access to the literature for all known occurrences of alkaline igneous rocks and carbonatites of Antarctica, Asia and Europe excluding the former USSR, Australasia and oceanic islands. More than 1,200 occurrences from 59 countries are outlined together with those of 57 oceanic islands and island groups. The descriptions include geographical coordinates and information on general geology, rock types, petrography, mineralogy, age and economic aspects with the principal references cited. There are 429 geological and distribution maps and a locality index. As has been demonstrated by the three earlier volumes, the present book is likely to be of considerable interest to mineral exploration companies, as there are no comprehensive published reviews of the economic aspects of the alkaline rocks. It will also interest research scientists in the fields of igneous petrology and volcanology, and geologists concerned with the regional distribution of igneous rocks and their geodynamic relationships.

Book Synopsis Antarctic Earth Science by : R. L. Oliver
Download or read book Antarctic Earth Science written by R. L. Oliver and published by Cambridge University Press. This book was released on 1983 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fourth international symposium on Antarctic Earth Sciences took place in Adelaide, South Australia during the week 16-20 August 1982. This volume contains a record of the centenary activities celebrating Sir Douglas Mawson and the one hundred and seventy-four papers that were presented by delegates for discussion over the five days. Sir Douglas Mawson was part of the first team to reach the magnetic South Pole, a leading geologist and scientific figure during the heroic age of of antarctic exploration. The papers presented during the symposium were divided into fifteen categories covering east and west Antarctica, marine, land and glacial geology, plate tectonics, islands, peninsulas, climatic change and Precambrian and Cenozoic era activity. The two hundred persons from sixteen countries who attended the symposium brought together a wide range of the most current expertise and research to share, of which this volume provides a record.
Book Synopsis Geologic History and Petrogenesis of Alkaline Volcanic Rocks, Mt. Morning, Antarctica by : Harold Lee Muncy
Download or read book Geologic History and Petrogenesis of Alkaline Volcanic Rocks, Mt. Morning, Antarctica written by Harold Lee Muncy and published by . This book was released on 1979 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Rocks exposed at Gandalf Ridge on the northern slopes of Mt. Morning represent the earliest documented evidence of volcanism in the Erebus volcanic province and the McMurdo Volcanic Group. K/Ar dating of samples from Gandalf Ridge suggests a mid-Miocene age (15.4 m.y. to 18.73 m.y.). The rocks range in composition from trachyandesite to quartz trachyte and pantellerite. Two different trends, one non-peralkaline and one peralkaline, are recognized. The non-peralkaline trend is represented by a trachyandesite-quartz trachyte sequence and the peralkaline trend by a trachyandesite-comenditic trachyte-comendite-pantellerite sequence. Major, trace, and rare earth element data are consistent with the trachyandesite being derived from an alkali basalt parent by fractional crystallization of olivine, clinopyroxene, feldspar, opaque oxides and apatite. The volcanism at Mt. Morning is believed to have been associated with the fracturing caused by an extensional tectonic regime. This regime is consistent with the widespread alkaline volcanism and the known crustal thinning in the western Ross Sea. These rocks are part of the McMurdo Volcanic Group.

Book Synopsis The Transantarctic Mountains by : Gunter Faure
Download or read book The Transantarctic Mountains written by Gunter Faure and published by Springer Science & Business Media. This book was released on 2010-09-21 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a summary of the geology of the Transantarctic Mountains for Earth scientists who may want to work there or who need an overview of the geologic history of this region. In addition, the properties of the East Antarctic ice sheet and of the meteorites that accumulate on its surface are treated in separate chapters. The presentation ends with the Cenozoic glaciation of the Transantarctic Mountains including the limnology and geochemical evolution of the saline lakes in the ice-free valleys. • The subject matter in this book is presented in chronological order starting about 750 million years ago and continuing to the present time. • The chapters can be read selectively because the introduction to each chapter identifies the context that gives relevance to the subject matter to be discussed. • The text is richly illustrated with 330 original line drawings as well as with 182 color maps and photographs. • The book contains indexes of both subject matter and of authors’ names that allow it to be used as an encyclopedia of the Transantarctic Mountains and of the East Antarctic ice sheet. • Most of the chapters are supplemented by Appendices containing data tables, additional explanations of certain phenomena (e.g., the formation and seasonal destruction of stratospheric ozone), and illustrative calculations (e.g., 38Cl dates of meteorites). • The authors have spent a combined total of fourteen field seasons between 1964 and 1995 doing geological research in the Transantarctic Mountains with logistical support by the US Antarctic Program. • Although Antarctica is remote and inaccessible, tens of thousands of scientists of many nationalities and their assistants have worked there and even larger numbers of investigators will work there in the future.

Book Synopsis The Petrology, Geochemistry, and Geochronology of Hotspot Seamounts in the North Pacific and Arc/backarc Volcanism on the Northern Antarctic Peninsula by : Randall Arthur Keller
Download or read book The Petrology, Geochemistry, and Geochronology of Hotspot Seamounts in the North Pacific and Arc/backarc Volcanism on the Northern Antarctic Peninsula written by Randall Arthur Keller and published by . This book was released on 1996 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic rocks from hotspots and island arcs/backarcs typically have enriched trace element and isotopic compositions that contain a contribution from subducted oceanic crust. Isotopic and trace element data suggest that the enriched components in hotspot volcanism are ancient subducted sediment and crust, and the enriched components in arc/backarc volcanism are hydrous fluids and melts from the subducting slab. This thesis examines the origins of these enriched components, and how they change in time and space. The Hawaiian-Emperor seamount chain records over 81 million years of volcanism from the Hawaiian hotspot. Seamounts at the old (northern) end of the chain have isotopic compositions more depleted then anything previously reported from the Hawaiian hotspot. Detroit seamount (81 Ma) has the most depleted composition, and was created while an active spreading ridge was close to the hotspot. Proximity to a spreading ridge must have caused the hotspot to entrain and melt more of the depleted upper mantle. The Patton-Murray seamount platform, at the old end of the Cobb hotspot track in the Gulf of Alaska, was volcanically active at 33 Ma, 27 Ma, and 17 Ma. The 33 Ma tholeiitic phase and 27 Ma alkalic phase are related to passage over the hotspot. The 17 Ma phase erupted too late to be directly related to the hotspot, but may have been caused by minor extension along a zone of weakness originally created by passage over the hotspot. On the northern Antarctic Peninsula, volcanism occurred above a subducting slab up to 360 km from the South Shetland Trench. Volcanism on the South Shetland Arc has enriched trace element and isotopic compositions that can be modeled by mixing of subducted sediments and depleted mantle. Backarc basin volcanism in Bransfield Strait contains less of the subducted component, and the most depleted samples are distinguishable from MORB only by their slightly elevated Cs and Pb concentrations. Extreme-backarc volcanism on James Ross Island (360 km from the trench) shows no evidence for the subducted component in its trace element compositions, but its Pb isotopic ratios are affected by Pb from subducted sediment.
