Document Summary

A stress due to a force pushing together on a body. confining pressure. Pressure applied equally on all surfaces of a body; also called geostatic or lithostatic pressure. contact metamorphism. Metamorphism under conditions in which high temperature is the dominant factor. differential stress. When pressures on a body are not of equal strength in all directions. ductile (plastic) Capable of being molded and bent under stress. foliation. Parallel alignment of textural and structural features of a rock. gneiss. A metamorphic rock composed of light and dark layers or lenses. gneissic. The texture of a metamorphic rock in which minerals are separated into light and dark layers or lenses. hornfels. Rock deposited by precipitation of ions from solution in hot water. isotherm. A line along which the temperature of rock (or other material) is the same. marble. A coarse-grained rock composed of interlocking calcite (or dolomite) crystals. metamorphic facies.
