Paleostress Inversion Techniques: Methods and Applications for Tectonics is an ideal reference for both academic and industry researchers in the Earth Sciences. The book introduces the methodologies developed to reconstruct (paleo) stress tensors from geological data. The interest and potential outcomes of the methods are illustrated by practical examples and supplementary electronic material and an overview on future research directions. As paleostress inversion methods are particularly useful in tectonic analyses at regional and local scales and their outcomes are relevant when trying to predict the orientations of fracture sets and potential fluid flow paths and associated mineralizations, this book provides an ideal resource. Includes detailed explanations of methods, along with concrete applications of paleostress inversion techniques Clearly illustrates the outcomes, advantages and limitations of the techniques Serves as a practical guide for both academics and industry researchers interested in structural geology, geodynamics and tectonics

Based on the Tenth International Basement Tectonics Conference held at the University of Minnesota-Duluth in August 1992, this volume contains 19 papers, 13 of which focus on the Middle Proterozoic Midcontinent Rift. An introductory essay discussing the Middle Proterozoic to Cambrian rifting in central North America is followed by contributions addressing topics including the Midcontinent Rift in Michigan and Minnesota, the Port Coldwell veins of northern Ontario, and petrography and sedimentation in the western Lake Superior region. The last five papers deal with the pre-Mount Simon basins of Ohio, the English Graben and the newly proposed East Continent Rift Complex, the Reelfoot Rift/Rough Creek Graben in the evolution of the Illinois Basin, and the A-type sheet granites in the Oklahoma Aulacogen of Cambrian age.

This lively introduction to geologic fracture mechanics provides a consistent treatment of all common geologic structural discontinuities. It explores the formation, growth and interpretation of fractures and deformation bands, from theoretical, field and lab-based perspectives, bridging the gap between a general textbook treatment and the more advanced research literature. It allows the reader to acquire basic tools to interpret discontinuity origins, geometries, patterns and implications using many of the leading and contemporary concepts known to specialists in the field. Problem sets are provided at the end of each chapter, and worked examples are included within each chapter to illustrate topics and enable self-study. With all common geologic structures including joints, hydrofractures, faults, stylolites and deformation bands being discussed from a fresh perspective, it will be a useful reference for advanced students, researchers and industry practitioners interested in structural geology, neotectonics, rock mechanics, planetary geology, and reservoir geomechanics.

The geometry of faults and fault systems affects the source mechanics of earthquakes and the deformation associated with slip on faults. This dissertation investigates aspects of the geometry of fault surfaces, in particular those with non-planar topology. I quantify the surface geometry using the tools of differential geometry to evaluate the geometry in a spatially coherent way. The study finds that at cm-scale ([approximately equal to]2cm) fault surfaces have no clear pattern of basic shapes succession, while at larger scales (10cm-50cm) corrugations along the slip direction are predominant while small undulations parallel to the direction of sliding exist on the cm-scale. The changes in surface shape and orientation lead to changes in resolved traction on the order of a few MPa for crustal settings, which far exceed generally associated triggering stresses. The undulations significantly retard slip on heuristic faults when compared to those lacking undulations. Geometric fault surface complexity on a crustal scale faults is investigated using relocated seismicity from a catalog of events for the Joshua Tree - Landers earthquake sequence. The spatial density of seismicity is used to locate finite width fault zones and construct surfaces indicative of the centers of these fault zones. The method identifies ten separate faults that exhibit significant non-planar geometry. The mechanical effects of the geometrically complex fault surfaces are illustrated using solutions to the quasi-static boundary value problem. I investigate the resultant stresses and tractions induced by slip on the Joshua Tree fault before the rupture of the Landers earthquake. The propensity for slip on the Landers faults is increased in regions of initiation and largest slip during the subsequent event. The geometrically complex models predict greater propensity for slip along the northern faults involved in the Landers earthquake than the commonly used planar and vertical four-fault models. The stresses adjacent to the Joshua Tree fault are investigated by calculating the changes in Coulomb stresses on optimally oriented surfaces of weakness. The geometrically complex model for Joshua Tree fault predicts the aftershocks immediately following the Joshua Tree earthquake quite well, and better than the planar fault model. Stress inversions are a useful and popular tool for structural geologist and seismologist alike. Many studies employ these methods on isolated faults or on fault system with limited ranges of orientations, which can lead to erroneous results. I propose a new method that incorporates the effects of mechanical interaction of the entire fault or fault system, solves the complete mechanical boundary value problem problem rather than employing empirical relationships between slip and stress or strain (faultless inversion). The method is tested on synthetic faults with various orientations to evaluate the effects of non-planarity and I find that the lack of varying normal vector orientations can introduce significant errors even for simple idealized cases. The effect of diversity of fault orientations are tested and the results indicate that faultless inversions do not perform as well for limited ranges of orientations when compared to the proposed method. The 1999 Chi-Chi, Taiwan, earthquake is used to test the proposed method. The resulting stress orientations are in good agreement with results from faultless inversions. Furthermore, slip distribution results are in general agreement with kinematic slip inversions using co-seismic surface deformation. Stress inversion methods using fault slip data can thus be improved upon, significantly in many cases, by solving a mechanical boundary value problem that takes into account the geometry of faults or fault systems.

The key driver for both the Hedberg conference and this publication was the recognition that knowledge of risk in the estimation of sealing capacity and fault-seal potential is important in making judgments at the exploration, appraisal, and development stages of the petroleum business. In addition, incorporating seal risk in the overall assessment of hydrocarbons in place can affect decisions to drill prospects and the location of appraisal and development wells, as well as reserve estimation.
