Laboratory study of 3D velocity distribution of P and S wawes in rocks: comparison of high pressure study and texture based calculated data

Popis výsledku v původním jazyce

The knowledge of 3D velocity distribution of P- and S-waves in rocks is very important parameter for interpretation and understanding the nature of seismic anisotropy observed in the earth?s crust and upper mantle. A new high-pressure measuring head wasdesigned and constructed to enable ultrasonic sounding of spherical rock samples in 132 independent directions under up to 60 MPa of acting hydrostatic pressure by means of simultaneous longitudinal and transversal sounding. New measuring system enablesultrasonic sounding of spherical rock samples by using a pair of P-wave sensors and two pairs of perpendicularly polarized S-wave sensors (TV and TH) see Fig.1. Shear wave sensors polarization is oriented according to rotation axis of the sample. An isotropic glass sphere was used to check and calibrate the new measuring setup. A spherical sample of a biotite gneiss from the Outokumpu was used for testing measurement. There is shown that both, P- and S-wave velocities, can be measured si
