dc.description.abstractUltrasonic pulse-broadening measurements at 1.0 MHz frequency have been carried out at the ambient conditions in a set of volcanic rocks of south-east Gujarat. The experimental data have been processed along with the results of P-wave velocity (Vp) measurements leading to the determination of internal friction (Qp-1) and attenuation (αp). The attenuation in rhyolites is relatively high (average Qp-1= 0.0051 , αp = 0.0330 dB/cm) compared to basalts (average Qp-1= 0.0019, αp = 0.0100 dB/cm) which are fine-grained and well crystallized. The mineral composition, in particular, the volume percentage of ground mass in rhyolites is found to have a strong control on both the attenuation and velocity of the rock samples tested. The experimental method is briefly described and the results obtained are presented and discussed.en_US
