Volcanic Degassing (Geological Society Special Publication) (No. 213)


Geological Society Publishing, "Volcanic Degassing (Geological Society Special Publication) (No. 213)"

Humans have long marvelled at (and feared) the odorous and colourful manifestations of volcanic emissions, and, in some cases, have harnessed them for their economic value. The degassing process responsible for these phenomena is now understood to be one of the key factors influencing the timing and nature of volcanic eruptions. Moreover the surface emissions of these volatiles can have profound effects on the atmospheric and terrestrial environment, and climate. Even more fundamental are the relationships between the history of planetary outgassing, differentiation of the Earth's interior, chemistry of the atmosphere and hydrosphere, and the origin and evolution of life.
This book provides a compilation of 23 papers that investigate the behaviour of volatiles in magma, the feedbacks between degassing and magma dynamics, and the composition, flux, and environmental, atmospheric and climatic impacts of volcanic gas emissions.

Tectonic, Magmatic, Hydrotherma, & Biological Segmentation at Mid-Ocean Ridges (Geological Society Special Publication)


Tectonic, Magmatic, Hydrotherma, & Biological Segmentation at Mid-Ocean Ridges (Geological Society Special Publication) By C. J. Macleod
Publisher: Geological Society of London 1996-11-01 | 258 Pages | ISBN: 1897799721 | PDF | 6 MB

We now recognize that mid-ocean ridges are not simple, two-dimensional features, but are instead partitioned into morphologically distinct segments on a variety of scales. Variations in axial morphology reflect differences in the structure of the magma reservoirs and in the nature of mantle upwelling beneath the ridge. Segment ends may be starved of magma, and spreading accommodated by tectonic stretching as well as by magmatic accretion. The location of the magmatic heat source and the distribution of permeability within the segment strongly control the geometry of seawater circulation in the crust and locus of hydrothermal discharge. In turn, the mechanisms of faunal colonization of vent sites and the evolutionary history of vent organisms depend strongly upon the spatial distribution of black smoker vents and the hydrodynamics of dispersal of the vent fluids. Segmentation, therefore, plays a vital role in the inter-relationship between all tectonic, magmatic, hydrothermal and biological processes at mid-ocean ridges. The recent research presented in this book, much of it carried out under the aegis of the British mid-ocean ridge 'BRIDGE' programme, examines this inter-relationship with the aim of furthering our understanding of the causes and consequences ofridge axial segmentation.

Modern Ocean Floor Processes and the Geological Record


Modern Ocean Floor Processes and the Geological Record (Geological Society Special Publication) By Robert A. Mills
Publisher: Geological Society of London 1998-12-01 | 303 Pages | ISBN: 1862390231 | PDF | 24 MB

This volume considers the geological processes at and biological colonization of, deep ocean spreading centres from both a modern, for example Mid-Atlantic Ridge, the East Pacific and the South West Indian Ridge, and an ancient perspective, such as in the UK, Cyprus, Turkey, Greece and the Urals.The book is one of the first attempts to bring together researchers from disciplines as diverse as geophysics and biology studying modern active hydrothermal systems and the fossilized remains of long-extinct hydrothermal systems that are now locked in the geological record.By using new knowledge of how hydrothermal systems function we can aid the understanding and prediction of mineral deposits now found on land.


The Future of Geological Modelling in Hydrocarbon Development - Special Publication no 309

The Future of Geological Modelling in Hydrocarbon Development - Special Publication no 309
Geological Society of London | January 15, 2009 | English | ISBN: 1862392668 | 225 pages | PDF | 7.95 MB

The 3D geological model is still regarded as one of the newest and most innovative tools for reservoir management purposes. The computer modelling of structures, rock properties and fluid flow in hydrocarbon reservoirs has evolved from a specialist activity to part of the standard desktop toolkit. The application of these techniques has allowed all disciplines of the subsurface team to collaborate in a common workspace. In today's asset teams, the role of the geological model in hydrocarbon development planning is key and will be for some time ahead.

Myth and Geology - Special Publication no 273 (Geological Society Special Publication)


L. Piccardi and W. B. Masse; Editors, "Myth and Geology - Special Publication no 273 (Geological Society Special Publication)"
Publisher: Geological Society of London | 2007 | ISBN 1862392161 | PDF | 346 pages | 13.4 MB

This book is the first peer-reviewed collection of papers focusing on the potential of myth storylines to yield data and lessons that are of value to the geological sciences. Building on the nascent discipline of geomythology, scientists and scholars from a variety of disciplines have contributed to this volume. The geological hazards (such as earthquakes, tsunamis, volcanic eruptions and cosmic impacts) that have given rise to myths are considered, as are the sacred and cultural values associated with rocks, fossils, geological formations and landscapes. There are also discussions about the historical and literary perspectives of geomythology. Regional coverage includes Europe and the Mediterranean, Afghanistan, Cameroon, India, Australia, Japan, Pacific islands, South America and North America. Myth and Geology challenges the widespread notion that myths are fictitious or otherwise lacking in value for the physical sciences.

The Geological Concept of Mountains in the Holy Qur'an" by Zaghlul R. El-Naggar

The study presented in this publication attempts to identify some of the relationships between recent findings in the field of geology and the meaning of some passages in the Qur'an. Some of these passages, which were revealed about 14 centuries ago,expressed certain geological facts, and it is only through some of the most recent geological findings of this century that these facts have become scientifically recognized. Other passages which contain indications of geological concepts are analyzed for additional details and explanations in this field.


The information in this study should be of great interest to both the Muslim and non-Muslim. It serves to strengthen the faith and to encourage the development of more scientific knowledge, and it adds a new dimension and perspective to geological research.
Author is considered an eminent scholar in the field of geology and has many publications, as well as participation in numerous conferences in his area. In this particular booklet, he analyzes in great detail a number of findings in geology and applies them directly to the understanding of Qur'anic passages which refer to the same subject.
The reader will find this material to be greatly stimulating, interesting and inspiring.
