Publisher's Synopsis
Knowledge of the seismic properties of minerals, rocks and ores has grown enormously, spurred by the determination of the structures and evolution of the earth using innovative seismologic technologies (eg reflection profiling, tomography, shear wave splitting), the mitigation of geological hazards (eg earthquakes and volcanic activity), and the exploration of mineral deposits, water and energy resources. This handbook provides engineers and scientists with a compact and sytematic compilation of the measured seismic properties of Earth materials. It contains all the reliable data of P and S wave velocities and anisotropy of various rocks, minerals and ores as functions of pressure and temperature.;The handbook is divided into two parts. The first part addresses the single crystal elasticity and seismic properties of 53 common rock-forming minerals, and the overall elastic moduli of their polycrystalline aggregates. This part begins with a simple introduction of the principles and methods for calculating the seismic properties of monophase and polyphase aggregates from single-crystal elasticity data. The second part deals with P- and S-wave velocities and anisotropy of various rocks, ores and mineral aggergates as functions of pressure, temperature and propagation and vibration directions. Also given are: geographic location, tectonic setting, lithology, original sample number, density, porsity, humidity (dry or wet) and source literature for each sample. Two tables also summarize chemical and mineral modal compositions of the samples whose seismic velocities and anisotropy have been measured. Finally, the book presents the relationship between seismic velocities (Vp and Vs) and density, seismic anisotropy and the mean Poisson's ratio of each main lithologic category, and the effects of phase transformation on seismic properties.
