Description: The principal task of the project is the investigation of the relationship between the texture and structure of rocks and their physical properties, especially the kinematic and dynamic parameters of ultrasonic waves. The behavior of the above-mentioned phenomena under confining pressure will also be studied. The proposed approach is based on texture determination by neutron diffraction, textural analysis by conventional optical microscopy, microstructural and fractographic analysis by image analysis and on the determination of properties of acoustic waves after passing through the rock sample. From core samples supplied the spherical specimens will be prepared for P-wave anisotropy measurement under confining pressure up to 400 MPa (approximate depth 15 km) and for texture analysis by neutron diffraction method. Surrounding material will be used for detailed petrology study. |
