Abstract

Summary

Authors have shown analysis of results of acoustic properties investigation of Pishchanka iron-ore structure (depth interval 144–273 m). Based on measured velocities of quasi-longitudinal and two quasi-transverse waves anisotropy parameters were calculated. Anisotropy coefficients analysis was performed using different methodologies: compressional, shear and acoustic. Vast majority of samples have high and average level of acoustic anisotropy of an ellipsoid. Based on acoustic tensor parameters most samples have rhombic symmetry type, minority - transverse-isotropic, what describes complex origin of the rocks on different depths. Dissidences in anisotropy parameters of given samples can be explained by essential difference in samples’ structures and discrepancy of size and form of the minerals’ grains.
