Book excerpt: Four hundred and seventeen shear and compression tests were completed on five minerals: olivine, enstatite, diopside, labradorite, and pyrope garnet. These minerals are assumed to represent the principal constituents of an upper mantle rock model. Petrographic examination and x-ray analyses indicate that the minerals deform cataclastically at low pressures and temperatures, with intragranular flow beginning at 30 kb normal pressure. Temperature enhances ductility, indicated at high pressures by x-ray line broadening on diffraction patterns and the appearance of kink bands in thin sections. Two phenomena of geophysical importance have been discovered during shear testing: (1) dehydration of less than 5 percent by volume of serpentine weakens dunite by more than 30 percent as the temperature is raised from 300C to 520C; (2) orthorhombic enstatite readily inverts to monoclinic polymorph under the influence of shear stress at all pressures and the temperatures to 920C and 50 kb. The inversion is accompanied by a small, rapid change in volume, sufficient to yield seismic energy for the production of a moderate earthquake. (Author).

This book was released on 1967 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The shear strength of grossly deformed tungsten, germanium, nickel, beryllium, uranium, copper, gold, silver, aluminum, magnesium, bismuth, and tin was measured in an opposed anvil shear apparatus at pressures up to 150 kb at 27C, and for gold, silver, and copper to 900C. The shear data agree with independent strength measurements at low pressures, but differ significantly from high-pressure shear-strength measurements made by other investigators. The data on the noble metals also fit a simple empirical formula relating the temperature and pressure dependence of the shear strength. (Author).
