Mantle Plumes

A Multidisciplinary Approach

Herausgegeben: Ritter, Joachim R. R.; Christensen, U.R.

Beschreibung

The concept of mantle plumes, originally suggested by Morgan (1971), is widely but not unequivocally accepted as the cause for hotspot volcanism. Plumes are thought of as deep-rooted, approximately cylindrical regions of hot rising mantle rock with a typical diameter of 100-200 km. Pressure-release melting near the b- tom of the lithosphere produces magmas that rise to the surface and lead, when the plate moves relative to the plume, to a chain of volcanic edifices whose age p- gresses with increasing distance from the plume. For a long time, the evidence for mantle plumes has been largely circumstantial. Laboratory and computer models of mantle convection show that under certain conditions plume-like structures can be found, and these simulations have been used to characterise their properties. Geodetic signals, such as topographic swells and associated geoid anomalies which surround the volcanic hotspots, support the plume hypothesis. They are best identified in an oceanic environment where the plume signal is usually less s- ceptible to be masked by effects of crustal or lithospheric heterogeneities. The i- topic and trace element composition of hotspot lavas differs from those of m- oceanic ridge basalts which is interpreted as indication for a source reservoir d- ferent from average upper mantle rock. The idea of mantle plumes has gained widespread popularity in various disciplines of Earth science and has been used, sometimes perhaps excessively, to explain volcanic and other phenomena.

Autor

Joachim R. R. Ritter is an expert in seismological experiments and seismic tomography. He has conducted research at volcanic fields in East Africa, California and Central Europe to reveal the deep roots of the magmatic processes. He is working at the Geophysical Institute at the University of Karlsruhe. Ulrich R. Christensen is a director at the Max Planck Institute for Solar System Research in Lindau Katlenburg. He applies fluid dynamics to study the dynamic processes in planets.

Rezensionen

Aus den Rezensionen: "... Das Buch beginnt mit einer Einführung in das Thema 'Mantle Plumes' und ihren Eigenschaften. ... Den Abschluß bilden 16 Farbtafeln ... Die Literaturzitate finden sich jeweils am Ende jedes Artikels. ... Positiv zu vermerken ist der Gesamtindex, der in vielen Werken sonst nicht vorhanden ist. Die Artikelsammlung fasst die neueste Literatur über Plumes zusammen und liefert viele multidisziplinär erfasste Daten aus dem Eifel-Plume. ... Das vorliegende Buch ist für Geologen, Mineralogen, Geophysiker, Geochemiker und Vulkanologen ... gedacht und sollte in keiner geowissenschaftlichen Bücherei fehlen ..." (C. SCHMITT-RIEGRAF, in: Zentralblatt für Geologie und Paläontologie, 2008, Issue 5-6, S. 997ff.)

From the reviews:

"This book, with 16 chapters and color plates, covers a diversity of topics dealing with the recognition and characterization of mantle plumes. ... There is a wide range in the depth of coverage and quality of the papers in the book. Some chapters are review papers and some are papers presenting new data. The book presents a good balance between geophysical and geochemical topics. ... The intended audience of the book are primarily geophysicists and geochemists interested in the mantle." (Kent C. Condie, Eos, Vol. 89 (11), 2008)

"The book comprises 16 individual papers, each focusing on a particular volcanic region or geological discipline. ... This means that the papers will be useful to a wider range of

people ... . As well as appealing to experts due to the inclusion of research at the forefront of the field, this book is accessible to non-experts thanks to the comprehensive background summaries and method explanations. Each paper is written as a self-contained unit making it easy for readers to dip in ... ." (Bryony Youngs, Geological Magazine, Vol. 145 (4), 2008)

"The mantle plumes, a term coined by J. Tuzo Wilson in 1963, are still controversial issue, particularly in terms of their depth of origin, their morphology, their longevity, even their existence. ... this book aims to bring some order to the discussion on this topic. ... This volume will be interesting to geologists and geophysicists from various disciplines of the Earth sciences, particularly geodynamics, geochemistry, and seismic tomography. It also will be very useful for recent graduated students at geological and geophysical faculties." (Marek Lewandowski, Pure and Applied Geophysics, Vol. 166, 2009)
