An introduction to the thin section description and interpretation of metamorphic rocks, their textures, and microstructures, for advanced undergraduate and graduate geology students. Sections cover some of the broader aspects of metamorphism and metamorphic rocks, the basics of description and interpretation of the textural/microstructural features from the simplest to the more complex, and advanced interpretations in polydeformed and polymetamorphosed rocks.

Mechanical properties and fluid transport in rocks are intimately linked as deformation of a solid rock matrix immediately affects the pore space and permeability. Part I of this topical volume covers mainly the nucleation and evolution of crack damage in rocks, new or modified techniques to measure rock fracture toughness and a discussion of upscaling techniques relating mechanical and fluid transport behaviour in rocks at different spatial scales.
Scientists examine tectonic faulting on all scales--from seismic fault slip to the formation of mountain ranges--and discuss its connection to a wide range of global phenomena, including long-term climate change and evolution. Tectonic faults are sites of localized motion, both at the Earth's surface and within its dynamic interior. Faulting is directly linked to a wide range of global phenomena, including long-term climate change and the evolution of hominids, the opening and closure of oceans, and the rise and fall of mountain ranges. In Tectonic Faults, scientists from a variety of disciplines explore the connections between faulting and the processes of the Earth's atmosphere, surface, a...
The proceedings of the 30th International Geological Congress held in Beijing, China in August 1997. This volume focuses on Precambrian geology and metamorphic petrology. It aims to present a view of contemporary geology to researchers interested in the geological sciences.
This monograph deals with the part of the field of experimental rock deformation that is dominated by the phenomena of brittle fracture on one scale or another. Thus a distinction has been drawn between the fields of brittle and ductile behaviour in rock, corresponding more or less to a distinction between the phenomena of fracture and flow. The last chapter deals with the transition between the two fields. In this new edition an attempt has been made to take into account new developments of the last two and a half decades. To assist in this project, the original author greatly appre- ates being joined by the second author. The scope of the monograph is limited to the mechanical properties o...
This book is a systematic guide to the recognition and interpretation of deformation microstructures and mechanisms in minerals and rocks at the scale of a thin section. Diagnostic features of microstructures and mechanisms are emphasized, and the subject is extensively illustrated with high-quality color and black and white photomicrographs, and many clear diagrams. After introducing three main classes of deformation microstructures and mechanisms, low- to high-grade deformation is presented in a logical sequence in Chapters 2 to 5. Magmatic/submagmatic deformation, shear sense indicators, and shock microstructures and metamorphism are described in Chapters 6 to 8, which are innovative chap...
This volume presents a selection of papers showing the current focus of studies of deformation structures and processes within the continental crust. The selected contributions use a large range of analytical techniques suited to the full range of structure sizes and fine-tuned to the physical process that controls the deformation, from the grain boundary at the micro-scale, the lithological contact at the meso-scale to the plate boundary at the global scale. The papers in the volume are grouped into three sections relating to specific lines of research within the analysis of rock deformation structures and processes, in particular in respect to the continental crust: structures within shear zones and faults; magmatic structures, and microstructures and rheology. These sections include papers describing field studies, experimental rock deformation and numerical modelling of deformation processes.
This collection of research and review papers addresses the question of structural evolution during deformation to high strains and the physical properties of rocks that have been affected by high-strain zones. The discussions range from natural examples at outcrop to microscopic studies. They include experiments and numerical models based on the active processes in high-strain zones as well as studies on the physical properties of highly strained rocks in the field and laboratory. Specific questions addressed include magnetotelluric imaging of faults, magnetic fabrics, fabric development, seismic properties of highly strained rocks, change of rheology with strain, influence of melt on the localization of deformation, the relationship between deformation and metamorphism as well as new methods in the analysis of deformation. The book is aimed at an interdisciplinary group of readers interested in the effects of high strain in rocks.
Despite being the cleverest man on Earth, Jonas Glebe becomes the unwitting tool of a baleful intelligence. He hopes that his new invention, the G-Bomb, will bring riches to himself and his daughter Margaret--but instead, it brings death, and a deadly threat to mankind. Val Turner knows the danger, but he is imprisoned, having been framed for Margaret’s murder. When Val’s eventually released, he’s too late to prevent the cataclysm that has engulfed the world. But fate intervenes: he saves a strange little man from drowning, and thereby changes the destiny of the world....
