Book excerpt: During the final year of the grant, we have investigated (1) why the strengths of rocks decrease with increasing temperature and in the presence of water through study of the fracture process in Westerly granite and Sioux quartzite specimens deformed in extension (some in true tension), (2) frictional strengths of rocks at high temperatures, (3) the stability of boreholes in fractured rock, and (4) slip in biotite single crystals (in that biotite is probably the weakest and most ductile of the common constituents of crystalline rocks.

This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the research performed to gain a fundamental understanding of the mechanical and transport properties of rocks under confining pressure and elevated temperature. There have been many contributions to our understanding of the mechanical behavior or rocks at high temperatures and pressures, but perhaps the three most outstanding contributions are the data which: (a) have helped to demonstrate the scientific feasibility of energy extraction from buried magma by assessing the likelihood of the rock mass to support stable boreholes at the pressures, temperatures (to partial melting), and aqueous conditions apt to occur in crystalline rocks above buried magma chambers; (b) have demonstrated that crystalline rocks deform primarily by brittle fracture when deformed at effective confining pressures to 200 MPa and temperatures to partial melting (to>1000°C), water-saturated or room-dry, and in constant strain rate tests (e dot = 10−4−1°sup -7//sec) or in creep tests; and (c) have shown that under these same conditions the time-dependent behavior of the rocks in the quasi-steady state regime is well described by the flow law: e dot = Asigma(superscript n)exp( -Q/RT) - a formulation previously thought to be applicable to rocks deforming primarily by crystal plasticity. This result suggests that fracture is also a time-dependent, thermally-activated process.
Download or read book Mechanical Behaviour of Rocks Under High Pressure Conditions written by Mitsuhiko Shimada and published by CRC Press. This book was released on 2000-01-01 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the mechanical properties of rocks at high pressure and temperature is fundamental not only for material science but also for earth science, such as for solving the mechanism of earthquakes and tectonic processes. For example, physical bases of the earthquake prediction based on the rock mechanics have been proposed, and extensive seismological, geophysical and geochemical observations have been conducted to find precursory phenomena before large earthquakes. However, we cannot help telling for the present that we do not have sufficient knowledge of an effective and reliable method for earthquake prediction. The book is mainly concerned with comprehensive source of information on the mechanical properties and behavior of rocks under high pressure that scans current state-of-the-art knowledge and shows contribution in establishing an experimental basis for the understanding of the mechanism of rock deformation in the earth's interior. The book can be used as textbook for graduate students by university teachers to prepare courses and seminars, and for active scientists and engineers who want to become familiar with a fascinating new field.

This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Research progress for the period March 1982 through October 1982 is reported. The permeability system that is nearing completion is briefly described. Several complementary experiments were conducted: (1) a study of the evolution of surfaces undergoing dissolution, with specific emphasis on the changes of surface roughness and asperity shape; and (2) an experiment to assess whether measureable pressure solution could occur in the time constraints typical of the proposed permeability experiments. (ACR).

This book was released on 1985 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pore-fluid chemical interactions on both short and long time scales can significantly change the permeability of a rock. Measurement of the permeability variations requires adaption and modification on standard measurement systems, with special attention given to pore-fluid flow rates and metal corrosion of system components. In this report, system requirements and capabilities are reviewed, analyzed, and recommendations made. Special attention is given to the choice of corrosion resistant metals, fluid-flow systems, back-pressure systems, jacketing materials, and flow-rate measurement. On the basis of this study, an economical, highly flexible, permeability system was designed and built. The system allows measurement of permeability over the darcy to nanodarcy range, using geologically meaningful, chemically reactive, pore fluids under constant volume flow rates as small as 0.2 ml/day at temperatures in excess of 300C, fluid pressures to 20 MPa, and confining pressures to 100 MPa. 7 refs., 3 figs., 1 tab.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of the geologic environment, exclusive of high temperature, have been studied for a number of mechanical properties of rocks. The influence of confining pressure, and strain rates and high pore pressure have been studied for brittle fracture, elastic properties, electrical resistivity, thermal conductivity, permeability and sliding friction. The rocks studied were typical crustal varieties, ranging in composition from granite to peridotite. We have applied our results to shallow focus earthquakes and to the mechanics of faulting in the earth. (Author).
