In modified hard phase to installation high quasihyperbolic pressure are studied by a ultrasonic method of speed longitudinal Vp, cross-section Vs waves and also density of magmatic rocks. On the basis of an experimental material about speeds of elastic waves and density of rocks at high thermobaric conditions are calculated elastic parameters and Poisson factor. The analysis of the received settlement data shows that changes of size of elastic parameters for different deep rocks explains possible variations of material structure of litosphere of the Earth. It was determined connection of modules of elasticity and Poisson factor from mineral structure and structural features of studied environments and their increase with growth of basicity of igneous rocks.
