Available in PDF, EPUB and Kindle. Book excerpt: During the last few years, carbonatites have received a considerable amount of attention. Some of this interest was no doubt kindled by the importance of volatiles in the Earth's mantle, particularly CO , by the fact that carbonatites 2 can be used to monitor the chemical evolution of the sub-continental upper mantle, and by the fact that carbonatites may be effective metasomatizing agents at both mantle and crustal levels. The interest in Oldoinyo Lengai has extended over at least 100 years, but it was not until the eruptions of 1960, when the unique carbonatitic nature of its lavas was recognized, that the volcano took on special significance in volcanology and igneous petrology. The recognition of carbonatitic flows coin cided with the first successful laboratory experiments carried out on carbonatitic melts. Since then, Oldoinyo Lengai has formed a cornerstone in all carbonatite discussions. It is probably true to say that the findings from Oldoinyo Lengai have dominated our ideas about carbonatites, in spite of the fact that the alkali rich, natrocarbonatitic lavas of Oldoinyo Lengai are markedly different from other carbonatites.

Download or read book The Gregory Rift Valley and Neogene recent Volcanoes of Northern Tanzania written by John Barry Dawson and published by Geological Society of London. This book was released on 2008 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure and volcanic activity of the northern Tanzania sector of the Gregory Rift Valley have hitherto been less well described than those in Ethiopia and Kenya. This book focuses on northern Tanzania where, although the volcanic area is smaller than those to the north, there are major features such as Kilimanjaro, the highest mountain on the African continent; Ngorongoro, one of the largest calderas on Earth; and Oldoinyo Lengai, the world's only active carbonatite volcano. Following an account of the discovery and early exploration of the rift valley, there are descriptions of the individual volcanoes. These are set within the context of the regional geology and geophysics of the rift valley, and in relation to the structural evolution of the rift and its associated sedimentary basins which include Olduvai, an important site in the history of human evolution The volume concludes with a discussion of the volcanism as related to the plume-related African Superswell.

Download or read book Igneous Rocks and Processes written by Robin Gill and published by John Wiley & Sons. This book was released on 2010-02-15 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for geoscience students taking introductory or intermediate-level courses in igneous petrology, to help develop key skills (and confidence) in identifying igneous minerals, interpreting and allocating appropriate names to unknown rocks presented to them. The book thus serves, uniquely, both as a conventional course text and as a practical laboratory manual. Following an introduction reviewing igneous nomenclature, each chapter addresses a specific compositional category of magmatic rocks, covering definition, mineralogy, eruption/ emplacement processes, textures and crystallization processes, geotectonic distribution, geochemistry, and aspects of magma genesis. One chapter is devoted to phase equilibrium experiments and magma evolution; another introduces pyroclastic volcanology. Each chapter concludes with exercises, with the answers being provided at the end of the book. Appendices provide a summary of techniques and optical data for microscope mineral identification, an introduction to petrographic calculations, a glossary of petrological terms, and a list of symbols and units. The book is richly illustrated with line drawings, monochrome pictures and colour plates. Additional resources for this book can be found at: http://www.wiley.com/go/gill/igneous.
Download or read book The Aln Carbonatite Complex Central Sweden written by Peter Kresten and published by Springer. This book was released on 2018-07-03 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This GeoGuide provides an overview of the geology of Alnö, combined with an up-to-date field itinerary. Covering all major geological aspects, it offers an essential summary of Alnö and its intriguing magmatic rocks in a compact form suitable for field excursions and home study alike. As one of the type localities for carbonatite, the late Proterozoic Alnö ring complex has been a crucial site for carbonatite-related research (next to the Fen complex in Norway), and provided one of the earliest test beds for this unique group of igneous rocks. Five geological excursions introduce the visitor to the most rewarding outcrops, including detailed descriptions and a wealth of high-quality colour photographs. The excursions are complemented by a detailed review of the history of scientific investigation on Alnö and, in particular, a catalogue of exotic and common minerals associated with the complex’s carbonatitic and alkaline silicate rocks. Finally, a summary of its trace element and isotope geochemistry as well as a brief outlook on Alnö’s potential as a future source of Rare Earth Elements (REEs) completes the book.
Download or read book Cenozoic Volcanism in the Tyrrhenian Sea Region written by Angelo Peccerillo and published by Springer. This book was released on 2016-12-01 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an updated edition of the book by the same author: "Plio-Quaternary volcanism in Italy - Petrology, geochemistry, geodynamics," published in 2005 by Springer. This edition has the same structure as the previous publication, with a general introduction; various chapters dedicated to different volcanic provinces in Italy; and a final chapter on the relationships between magmatism and geodynamics. It includes information that has become available in the last ten years, and new chapters have been added offering detailed discussions of the Oligo-Miocene orogenic volcanism on Sardinia and of some small outcrops of fragmented volcanic rocks occurring in several places of the Apennines. This new edition now covers the entire Tyrrhenian Sea magmatism of the last 40 Ma. Lastly, it includes two appendices: Appendix 1 reports on a comparison between the Tyrrhenian Sea volcanism and the partially coeval magmatism along the Alps and adjoining areas and has the objective of highlighting similarities and difference that can tell us much on geodynamics and magmatism between the converging plates of Europe and Africa. Appendix 2 is an update of the 2005 edition appendix and deals with classification of orogenic rocks with special emphasis on potassic alkaline volcanics.

Download or read book Volcanoes written by John P. Lockwood and published by John Wiley & Sons. This book was released on 2022-09-13 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: VOLCANOES Since the publication of the first edition of Volcanoes in 2010, our world of volcanology has changed in exciting ways. Volcanoes have continued to erupt (some 61 eruptions with VEI magnitudes greater than 3 have taken place since 2010), and in this revised and updated edition, the authors describe the largest of these, and the ones that have had the most impact on society. Volcanoes, Second Edition, contains more than 80 new photographs and figures to better illustrate volcanic features and processes, with an updated Bibliography that includes important papers describing recent eruptions and new findings. Volcanologic research is improving the foundations of knowledge upon which all our science rests, and we briefly summarize the most important of these advances and new research tools developed over the past eleven years. The most productive of these new tools are remotely operated, constantly monitoring volcanoes and their impacts on the Earth’s atmosphere from space and exploring new volcanic worlds beyond the bounds of Earth. Remotely Operated Vehicles (ROVs) are now widely available to understand better the most active volcanoes on Earth - those beneath the sea. This superlative textbook will enable students who may never see an erupting volcano to evaluate news stories about far-away eruptions, and to distinguish between overly sensational stories and factual reporting that puts facts in context. Emergency managers, land use planners, and civic officials also need to understand volcanic processes when their communities are threatened – this book will inform and guide them in their decision-making. Avoiding overly technical discussions and unnecessary use of jargon, with the important needs of civil authorities, teachers and students particularly in mind, this second edition of Volcanoes will also be of interest to general readers who are interested in these fascinating and ever-changing features of our dynamic planet.
Download or read book Volcanic Processes in the Sedimentary Record written by A. Di Capua and published by Geological Society of London. This book was released on 2023-04-18 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanoes and sedimentary systems are linked by a strong relationship. The ascent and eruption of magma liberates large volumes of material, through a variety of mechanisms, to the surrounding environment, with subsequent sediment input and transport influencing the evolution of that environment. This connection between volcanism and adjacent sedimentary systems has long attracted the attention of geologists, giving rise to an increasing body of academic research over the past three decades. Volcanic Processes in the Sedimentary Record: When Volcanoes Meet the Environment collects innovative works exploring how volcanoes and sedimentary systems interact, moving from the processes directly associated with eruptive behaviour, to the most distal sedimentary offshoots, where volcanogenic particles are accumulated during or after volcanic activity. In doing this, different volcanic and environmental settings are explored, travelling through space and time, showing how volcaniclastic detritus is produced and dispersed by volcanic, volcano-sedimentary and sedimentary mechanisms, via processes affecting development of volcanic edifices themselves through to the most distal depocentres.
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.
Download or read book Phoscorites and Carbonatites from Mantle to Mine the Key Example of the Kola Alkaline Province written by F. Wall and published by The Mineralogical Society of Great Britain and Ireland. This book was released on 2004-07-01 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phoscorites are dark, often very handsome, sometimes economically valuable, magnetite-apatite-silicate rocks, almost always associated with carbonatite. They are key to understanding the longstanding question of how carbonate and carbonate-bearing magmas rise to the crust and the Earths surface. Despite this, they have been given little attention; a search on geological literature databases will produce thousands of references to carbonatite (up to 4125 on Georef) but not more than thirty references to phoscorite. This book goes some way to redress this balance. Over recent years many European and North American scientists have studied Kola rocks in collaboration with Russian colleagues. The idea for this book came from one such project funded by the European organisation, INTAS (Grant No 97-0722). The Kola Peninsula is one of the outstanding areas in the World for the concentration and economic importance of alkaline rocks. However, Russian work on the Kola complexes is still relatively unknown and a particular aim of this book, as well as presenting current research, is to make this knowledge accessible to English language readers. A large exploration programme on Kola alkaline rocks was active from 1950 to 1990 and involved teams of geologists who studied many kilometres of drill core and carried out detailed mineralogical and petrological studies.

Download or read book Geology of National Parks of Central Southern Kenya and Northern Tanzania written by Roger N. Scoon and published by Springer. This book was released on 2018-04-09 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the interrelationship between the spectacular geology of an area of East Africa that includes a branch of the rift valley, as well as giant freestanding ice-capped mountains and extraordinarily toxic, alkaline lakes, and some of the greatest concentrations of wildlife on Earth. It suggests that geological processes that have shaped the iconic landforms, including active volcanoes, may also be responsible for the unusually diverse speciation which characterises the region. Moreover, it is not a coincidence that important palaeoanthropological discoveries have been unearthed in the region. National parks and conservation areas have tremendous potential for geotourism and the book assists both tour guides and visitors in this regard. In addition, the book may provide a better understanding to management of the importance of geology for sustaining wildlife.
