ABSTRACT For elastic waves in geomaterials, the method is proposed to determine experimentally the frequency dependence of attenuation factor by ultrasonic laser excitation and estimate the characteristic sizes of mineral grains. An example is shown for using the method in question for structural analysis of ferrous quartzite samples.
