Book Description
In the last decades, palaeomagnetic research has provided important information about the past variation of the Earth’s magnetic field (EMF) from its origin to the present day. However, questions regarding the origin and evolution of the EMF as well as the frequency and spatial distribution of its variations still remain open to debate. This Special Publication provides new insights into the study of the temporal and spatial evolution of the EMF presenting new data from palaeomagnetic and rock magnetic studies of archaeological materials, sediments and lavas. The papers presented cover a wide range of topics related to archaeology, stratigraphy and climate, including new data from several parts of the world, such as Europe, Africa, Australia, New Zealand, India and the Baltic Sea. This Special Publication aims to present an overview of the most recent secular variation studies and their use to disclose fundamental properties of the EMF evolution.
Oceanography and Marine Biology, An Annual Review, Volume 40
Author: R. N. GibsonPublisher: CRC Press
ISBN: 1134523149
Category : Science
Languages : en
Pages : 981
Book Description
Interest in oceanography and marine biology and its relevance to global environmental issues continues to increase, creating a demand for authoritative reviews that summarize recent research. Oceanography and Marine Biology: An Annual Review has catered to this demand since its foundation, by the late Harold Barnes, more than 40 years ago. It is an
Palaeomagnetism and Tectonics of the Mediterranean Region
Author: Antony MorrisPublisher: Geological Society of London
ISBN: 9781897799550
Category : Science
Languages : en
Pages : 438
Book Description
The Mediterranean region represents a complex mosaic of continental, microcontinental and ophiolitic terranes, whose overall evolution has been controlled by relative movements between the African and Eurasian plates. Palaeomagnetic studies have played an important part in deciphering the sequence of tectonic events in this region. The 33 papers presented here span the full width of the Mediterranean basin and present results from Permian to Quaternary rocks.
Geodynamics and Ore Deposit Evolution in Europe
Author: D. BlundellPublisher: Newnes
ISBN: 0080931340
Category : Science
Languages : en
Pages : 360
Book Description
This book presents a new synthesis of the major metallogenic provinces of Europe and the geodynamic processes involved that can lead to the formation of world-class ore deposits. It represents the culmination of a 5-year research programme, GEODE, set up by the European Science Foundation, that brought together researchers across Europe from a wide range of disciplines into collaborative research projects. They focused on five metallogenic provinces across Europe; the Precambrian Fennoscandian Shield, the Upper Palaeozoic Urals, the Variscides of France and SW Iberia, the Alpine–Balkan–Carpathian–Dinaride belt and sediment-hosted deposits of Europe. Because of the long and well-known tectonic history of Europe and the diversity of ore deposits, linkages between geodynamics and ore deposit evolution have been established and new insights into mineralizing fluids and ore formation processes have been gained. Presented as a set of individual review papers and a final synthesis, this book offers a coherent and structured appraisal of geodynamics and metallogeny in Europe, with valuable lessons for mineral exploration and research throughout the world.
The South Aegean Active Volcanic Arc
Author: M. FytikasPublisher: Elsevier
ISBN: 0080457576
Category : Science
Languages : en
Pages : 401
Book Description
This book is a collection of 22 selected papers from the homonymous Conference held in September 2003 Milos, Greece. The aim of the conference was to serve as a forum for the presentation and constructive discussion of the state-of-the-art and emerging issues on the South Aegean Volcanic Arc. In the first part of the book the tectonic- geodynamic setting and the present upper mantle structure of the Aegean area are discussed. It includes an interesting interpretation of data on the spatial distribution of intermediate focal depth earthquakes, fault plane solutions and deep velocity structures, to further investigate active tectonics related to the deep structure of the southern Aegean volcanic arc. The second part deals with general volcanological, petrological and tectonic characteristics of the SAAVA presenting an extensive review of volcanological, chemical, isotope and tectonic data, using a large amount of new field and laboratory data. Interesting conclusions are presented regarding the present volcanic associations, the volcanic fields location and shape in respect to the large tectonic lineaments and the plate motions, the source of the SAAVA parental magmas. Presented in the third part is an extensive review on the volcanic hazard assessment and the monitoring state of the SAAVA centers. Seismic and geodetic monitoring of the Santorini volcano and the recent (1995-1998) crisis of Nisyros volcano are presented and discussed. The last part deals with hydrothermal deposits and processes in the SAAVA, as well as products and processes in adjacent areas with a particular interest and significance that link them to the SAAVA processes. *Systematic re-evaluation on the geodynamic and tectonic setting of the Aegean active volcanic centers *Thorough review with new data and ideas on the magma source region, the magma differentiation processes in both the deep and shallow levels, and the volcanological processes related both to the magma composition and storage depth as well as to the tectonic regime of the volcano growth area *Up to date estimation of the volcanic hazard in the Aegean area, and a detailed presentation of the present state and the monitoring efforts of the South Aegean active centers

Environmental Problems in East-Central Europe
Author: Frank CarterPublisher: Routledge
ISBN: 1134688067
Category : Science
Languages : en
Pages : 517
Book Description
In this new edition, the progress made in the last decade to solve the environmental problems described in the first edition is assessed. The attempts to bring environmental legislation into line with West European norms is also described. Environmental Problems of East-Central Europe looks at air and water pollution, modern farming, water supplies, waste management and landscape protection. These topics are placed within economic, social and political profiles, as spending on a clean environment must be reconciled with welfare spending and the safeguarding of jobs, European Union assistance, civil society and the work of environmental NGOs are also discussed. All of these matters are considered within the context of the wider geographical area and then by each individual country, including the previously communist states lying to the west of the Soviet Union (now with the former federal states of Czechoslovakia and Yugoslavia broken up into seven different entities) and a review of the former Soviet Union with particular reference to the Baltic States. Environmental Problems in East-Central Europe provides a wealth of up-to-date reference material, with a vast amount of supporting literature on environmental conditions and the functioning of civil society and a map of each country. The environment is being taken seriously by them all, such is the influence of the Rio sustainability agenda in general and the EU environmental 'acquis' in particular. The book reveals that Eastern Europe is not a blighted area, but in some respects has a higher biodiversity than Western Europe. Although there is enormous waste and inefficiency in energy use, people actually consume relatively little and the East therefore has some lessons for the West in terms of managing on the bases of 'fair share' of the earth's resources.
