Download or read book The Initiation Propagation and Arrest of Joints and Other Fractures written by John W. Cosgrove and published by Geological Society of London. This book was released on 2004 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a state of the art look at our understanding of joint development in the crust. Answers are provided for such questions as the mechanisms by which joints are initiated, the factors controlling the path they follow during the propagation process, and the processes responsible for the arrest of joints. Many of the answers to these questions can be inferred from the geometry of joint surface morphology and joint patterns. Joints are a record of the orientation of stress at the time of propagation and as such they are also useful records of ancient stress fields, regional and local. Because outcrop and subsurface views of joints are limited, statistical techniques are required to characterize joints and joint sets. Finally, joints are subject to post-propagation stresses that further localize deformation and are the focus for the development of new structures.

Book excerpt: This study focuses on sub-parallel, clast-scale fracture patterns within conglomerates of Eocene-Miocene synextensional sedimentary strata of the Titus Canyon Formation in the Grapevine and Funeral Mountains of southwestern Nevada and southeastern California. Features including shear fractures and pressure solution depressions, cross-cut by subsequent point-contact deformation and sub-parallel fractures, have also proven to be essential in a understanding the mechanism that produces this systematic deformation. We propose that clast deformation occurs in 2 phases. Phase 1 involves pressure solution processes. Pressure solution depressions are recognized as shallow features that begin to develop at relatively low temperatures of 90±10°C and depths of approximately 2-5 km. With rapid uplift and erosion, Phase 2 conditions emerge and lead to sub-parallel fracture processes. Modeling clasts as Eshelby inclusions with an internally uniform stress field, imply that sub-parallel fracturing occurs with minimum confining pressure in the range of 2 to 30 MPa. This corresponds to relatively shallow depths of less than 1250 meters. With progressive deformation from the same remote stress during Phase 2 conditions, shear factures coalesce from sub-parallel fractures. Through kinematic analysis, we infer strain field orientations consistent with a minimum compressive stress in a NW/SE orientation. Further analysis of shear fractures and slickenlines implies a maximum compressive stress near 225°, 50° SW. Investigation of units below the Titus Canyon Formation show slickenlines with similar orientations that cross-cut ductile fabrics below regional detachments. Units above the Titus Canyon Formation suggest that conditions leading to sub-parallel fractures were either no longer present by Late Miocene time or that younger units were deposited during deformation, but were not exposed to the appropriate conditions required to induce fracturing. Altogether, these data suggest a common source for the stress field responsible for the deformation. Our estimates imply a stress field with a maximum compressive stress oriented near normal to the orientation of sub-parallel regional detachments. This possibly indicate the influence of near-field stresses associated with brittle rupture events on the fault as it was exhumed, or some other driving stress oriented in a similar orientation. We propose the Boundary Canyon detachment fault and Monarch Spring fault as likely candidate sources of this stress field.

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book excerpt: Presents a history of the Mojave Road, originally an Indian trail, from the first explorations in the 1820s to its years as a wagon road in the 1870s and 80s, focusing on that portion of the road from the California Desert to the Colorado River.
Download or read book Lithic Debitage written by William Andrefsky (Jr.) and published by . This book was released on 2001 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Debitage, the by-product flakes and chips from stone tool production, is the most abundant artifact type found on prehistoric sites. Archaeologists now recognise its potential in providing information about the kinds of tools produced, the characteristics of the technology that produced them, human mobility patterns and even site function, applying scientific analyses to its study. This volume brings together some of the most recent research on debitage analysis and intepretation, including replication experiments, and offers methodologies for interpreting variability in assemblages at the micro and macro level.
