Abstract: Seismic refraction surveys utilizing P & SH-waves were carried out over an abandoned quarry at Genting Highlands in order to study the anisotropy of the bedrock of that site. Shear (S) and compression (P) acoustic velocities of the subsurface refractor have shown significant variations in their spatial distribution. These variations in velocity values were compiled and then qualitatively correlated with surface fracture surveys conducted during the course of acquiring the field data.

Seismic P & SH-wave velocity values obtained from in situ measurements have been used for calculating the anisotropy percentage and slowness factor. The petrophysical parameters computed are then contoured to identify the orientation of fracture zones along the refractor surface.
