Adolphe Nicolas – författare

This book originates in the French classic "Principes de Tectonique" (Masson, 1983), written by professor Adolphe Nicolas, and the more recent "Principes de Tectonique" by J.L. Bouchez and A. Nicolas (De Boeck, 2018). This English edition is an up-to-date and augmented version that keeps the concise and rigorous writing of its inspiring predecessors. It is largely based on laboratory and field experience of both authors, with a focus towards hard rocks and magmatic rocks from both the continental crust worldwide and the mantle, principally from the Oman ophiolites. The book includes more than 250 illustrations, most of them original. In addition to classic geological subjects, the book includes elements such as plastic deformation of ice, quartz and olivine, fabric acquisition in rocks and magmas, measurement and orientation of stress, together with basic background information on neotectonics, geophysics and other practical tools such as magnetic fabrics not commonly treated in geological books. Since the targeted readers are present day young students, a few exercises of structural geology are included to improve their abilities.This book aims principally at students of Geology, at both the undergraduate and graduate levels. However, due to its numerous illustrations and rather concise writing, anyone interested in rock deformation and/or tectonics will find key answers in this book.

Over the past 20 years, geologists have come to realize that the real object of their studies is the Earth, and that their favorite subjects, whether basalts, earthquakes, or the Tibetan plateau (for example) are only the means to understanding the Earth itself as a complete entity. Geology has thus acquired aglobai perspective. The study of any particular regional problem is only of general interest in providing good foundations to investigate general phe­ nomena. But this same particular problem can only be completely understood ifits global context is taken into account. The geology of the Andes is only one of many examples of subcontinental subduc­ tion and, as such, its study contributes to our understanding of the mechanism of subduction. However, at the same time, understanding the geology of the Andes is today no longer possible without relating it to the geological history of the eastern Pacific, reconstructing the relative movements of the East Pacific Rise and the Nazca Ridge against South America and, in a wider sense, in the context of the his­ tory of the Pacific Ocean as a whole. Geology today is based on an infinite variety of natural examples which in the general frame of plate tectonics deals with geometrie objects, historie situations, or the various methods employed. The object "Earth" includes not only subjects like seismology, structural geology, and geochemistry, but also studies of the crust, mantle and core, oceans and continents, and mountain ranges and basins.

Teile der Kontinente enthalten trotz mehrfacher Umgestaltung durch die Plattentektonik noch Informationen über das initiale Stadium der Abkühlung des Planeten Erde. Im Gegensatz dazu ist in den Ozeanplatten die Geodynamik der Erde aufgezeichnet, wie sie sich in dem geologisch kurzen Zeitraum von 150 MA zwischen ihrem Entstehen an den mittelozeanischen Rücken bis zur Verschluckung in Subduktionszonen abspielt. Beim Studium der ozeanischen Rücken untersucht man den Antriebsmechanismus der geodynamischen Prozesse, die in der Erde ablaufen. Die Besonderheit dieses Buches liegt in der fruchtbringenden Verknüpfung von neuesten ozeanographischen Daten mit denen von Ophiolithen, die heute auf den Kontinenten befindlich, von ehemaligen Ozeanböden abgeschürft wurden. Dadurch entsteht das Bild von glutflüssigen untermeerischen Gebirgen, die immer wieder aufs neue junge Ozeanböden entstehen lassen. Das Buch ist vor allem für Studenten und Wissenschaftler der Geowissenschaften geschrieben. Es ist aber auch für ein breiteres Publikum geeignet, da der leicht verständliche Text durch zahlreiche meist farbige Abbildungen illustriert wird.
