Abstract
Investigations at the frequency of 10 MHz were made to study the attenuation and internal friction in limestone and taconite. An Ultrasonic Attenuation Comparator Model-9000 (Matec Inc.) with a ‘plug-in’ and X-cut quartz transducers was used for the tests. The velocity and attenuation measurements on the two rock types have not indicated any general and definite pattern. In limestone, the attenuation coefficient is practically constant in all three measured directions, whereas it varies with direction in taconite. The coefficient of viscosity can be calculated using ultrasonic measurements. The viscosity varies in different directions of limestone but such directional variations are small in taconite. The values of coefficient of viscosity obtained are lower in comparison to those determined by resonance method.
