Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
Paleomagnetic data are useful in many applications in Earth Science from determining paleocurrent directions to analyzing the long-term behavior of the geomagnetic field. Despite the diversity of applications, the techniques required to obtain and analyze the data are similar. This book attempts to draw together the various principles and practices within paleomagnetism in a consistent and up-to-date manner. It was written for several categories of readers: 1) for Earth Scientists who use paleomagnetic data in their' research, 2) for students taking a class with paleomagnetic content, and 3) for other professionals with an interest in paleomagnetic data. <...>
This book is the sequel to Palaeomagnetism and Plate Tectonics written by Michael W. McElhinny, first published in 1973. The aim of that book was to explain the intricacies of paleomagnetism and of plate tectonics and then to demonstrate that paleomagnetism confirmed the validity of the new paradigm. Today it is no longer necessary to explain plate tectonics, but paleomagnetism has progressed rapidly over the past 25 years. Furthermore, magnetic anomaly data over most of the oceans have been analyzed in the context of sea-floor spreading and reversals of the Earth's magnetic field. Oceanic data can also be used to determine paleomagnetic poles by combining disparate types of data, from deep-sea cores, seamounts, and magnetic anomalies. Our aim here is to explain paleomagnetism and its contribution in both the continental and the oceanic environment, following the general outline of the initial book. We demonstrate the use of paleomagnetism in determining the evolution of the Earth's crust. <...>
The lower Chickabally Mudstone Member of the Budden Canyon Formation is Ba'rfemian and probable lowermost Aptian in age. Its lower contact is gradational with the Roaring River Member 'of 'the formation, but is bounded above by an angular unconformity at the base of the Huling Member in the Mitchell Creek Area of the Ono Quadrangle. The unconformity is documented by the angular relation of beds in the two members, the thinning section in the lower Chickabally Member from southwest to northeast, and the cutting out of fossil zones in the lower Chickabally Member from south to north.
Early in the Mesozoic the western portion of the South American continent was subjected to differential but gentle crustal deformation which resulted in a series of crustal downwarps situated at intervals from Colombia on the north to Southern Patagonia on the south. These downwarps were in the nature of small geosynclinal troughs separated one from the other by peninsula-like land areas of probable low topographic relief.
Writing this history of paleontology has revived vivid fossil-related memories from my past. Ever since childhood I have been fascinated and inspired by the fragmentary vestiges of ancient creatures, the rubble of once great nations of animals. Every birthday I would plead with my parents to be taken to the Natural History Museum in London, in a more naive era when a small boy could be set free to explore the terracotta halls of this Romanesque “cathedral of life.” I loved the grand dinosaur skeletons, of course, although I was already aware that some of them were made of plaster, but it was the unfrequented gallery of ancient fish that I remember most. Even more than their spectacular land-living descendants, this gallery’s inhabitants looked intriguingly, overwhelmingly old—crushed and mangled messengers from an alien era before feet trod the Earth. Many appeared timid and harmless, yet some were heavily armored, hinting that some awful threat was abroad in those days. <...>

First of all I would like to express my deep gratitude towards Prof. Dr. rer. nat. Ralf Littke for giving me the opportunity to carry out my PhD studies at the Institute of Geology and Geochemistry of Petroleum and Coal and for his constant support throughout my studies and personal development.
