Palaeomagnetism in Fold and Thrust Belts: New Perspectives


Book Description

Palaeomagnetism is a technique used to understand complex deformation patterns in fold-and-thrust belts; it can be used to characterize the distribution, magnitude and timing of vertical axis rotations, an elusive variable using other methods. A combination of palaeomagnetic and structural geology analyses has helped to unravel the geometry and kinematics of fold-and-thrust belts around the world and of different geological ages for more than 50 years. This volume comprises three sections: the first shows thorough overviews of western Mediterranean arcs and the western Carpathians; the second depicts several examples from the Andes, the Alps, Anatolia, Pyrenees, Iberian Ranges and the Atlas; and the third shows the latest research on the use of palaeomagnetism to understand fold-and-thrust belts in 3D and 4D in a more quantitative way and it also includes some methodological proposals to avoid common errors. In the papers of the first two sections, the combination of palaeomagnetic analyses with structural data, AMS or magnetostratigraphic analyses demonstrate the usefulness of palaeomagnetism in deciphering complex deformation patterns in fold-and-thrust belts.

Kinematic Evolution and Structural Styles of Fold-and-thrust Belts


Book Description

Fold-and-thrust belts occur worldwide, have formed in all eras of geological time, and are widely recognized as the most common mode in which the crust accommodates shortening. Much current research on the structure of fold-and-thrust belts is focused on structural studies of regions or individual structures and on the geometry and evolution of these regions employing kinematic, mechanical and experimental modelling. In keeping with the main trends of current research, this title is devoted to the kinematic evolution and structural styles of a number of fold-and-thrust belts formed from palaeozoic to recent times. The papers included in this book cover a broad range of different topics, from modelling approaches to predict internal deformation of single structures, 3D reconstructions to decipher the structural evolution of groups of structures, palaeomagnetic studies of portions of fold-and-thrust belts, geometrical and kinematical aspects of Coulomb thrust wedges and structural analyses of fold-and-thrust belts to unravel their sequence of deformations--




250 Million Years of Earth History in Central Italy


Book Description

"The Umbria-Marche Apennines are entirely made of marine sedimentary rocks, representing a continuous record of the geotectonic evolution of an epeiric sea from the Early Triassic to the Pleistocene. The book includes reviews and original research works accomplished with the support of the Geological Observatory of Coldigioco"--




Thrust Tectonics


Book Description

K.R. McClay Department of Geology, Royal Holloway and Bedford New College, University of London, Egham, Surrey, England TW20 OEX. Since the first Thrust and Nappe Tectonics Conference in London in 1979 (McClay & Price 1981), and the Toulouse Meeting on Thrusting and Deformation in 1984 (Platt et al. 1986) there have been considerable advances in the study of thrust systems incorporating new field observations, conceptual models, mechanical models, analogue and numerical simulations, together with geophysical studies of thrust belts. Thrust Tectonics 1990 was an International Conference convened by the editor and held at Royal Holloway and Bedford New College, University of London, Egham Surrey, from April 4th until April 7th 1990. There were one hundred and seventy participants from all continents except South America. The conference was generously sponsored by Brasoil U.K. Limited, BP Exploration, Chevron U.K. Limited, Clyde Petroleum, Enterprise Oil, Esso Exploration and Production UK Limited, and Shell U.K. Exploration and Production. One hundred and five contributions were presented at the meeting, - seventy six oral presentations (together with poster displays) and an additional twenty nine posters without oral presentation (McClay 1990, conference abstract volume).




Structural Geology and Tectonics Field Guidebook — Volume 1


Book Description

This book helps a novice to explore the terrain independently. Geoscience fieldwork with a focus on structural geology and tectonics has become more important in the last few years from both academic and industrial perspectives. This book also works as a resource material for batches of students or geological survey professional undergoing training as parts of their course curriculum. Industry persons, on the other hand, can get a first-hand idea about what to expect in the field, in case no academic person is available with the team. This book focused on structural geology and tectonics compiles for the very first time terrains from several regions of the globe.




Paleomagnetic Rotations and Continental Deformation


Book Description

One of the most interesting results obtained in the last two decades in the study of crustal deformation has been the recognition that large regions of continental crust undergo rotations about vertical axis during deformation. Proof of such rotations has come through the paleomagnetic studies, which reveal rotations when paleomagnetic declinations within the deforming region arc compared with those found in coeval rocks in the stable regions outside the deforming zone. Such rotations were first described in Oregon then in the North American Cordilleras and in Southern California and were a surprise to everyone. Even in California which, as a result of oil exploration, was among the best geologically explored regions in the world, no one could claim to have predicted that these rotations would be found. Rotations have subsequently been found in other areas of recent continental tectonic activity, notably in the Basin and Range province, New Zealand, the Andes, Greece and Western Turkey, so that they appear as an important feature of continental deformation.

Teaching Methodologies in Structural Geology and Tectonics


Book Description

This edited book discusses various challenges in teaching structural geology and tectonics and how they have been overcome by eminent instructors, who employed effective and innovative means to do so. All of the chapters were written by prominent and active academics and geoscientists fully engaged in teaching Structural Geology and Tectonics. New instructors will find this book indispensible in framing their teaching strategy. Effective teaching of Structural Geology and Tectonics constitutes the backbone of geoscience education. Teaching takes place not only in classrooms, but also in labs and in the field. The content and teaching methodologies for these two fields have changed over time, shaped by the responsibilities that present-day geoscientists are expected to fulfill.




Palaeomagnetism and Tectonics of the Mediterranean Region


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.
