The method of seismic refraction is widely used in many applied Geology fields and problems today. Although it has some limitations, in the case of detecting a lower velocity bounded layer, this method is well tailored to a crystalline environments where, more often, weathering degree is highest on the surface and gradually decreases in depth and thus can aid in associating the weathering degree to velocity. Some relationships have been made to establish a connection between velocities and the elastic properties o...
