Assessments of Ultrasonic Pulse Velocity and Dynamic Elastic Constants of Granitic Rocks Using Petrographic Characteristics
Abstract The experimental work described in this paper was carried out in order to discover about the effects of petrographic characteristics on the ultrasonic pulse velocity and dynamic elastic constants of granitic rocks. For this, petrographic characteristics include the mean mineral grain size (MGS) and ratio of Quartz to Feldspar (Qz/Fl), ultrasonic pulse velocity include the P-wave (Vp) and S-wave velocity (Vs), and dynamic elastic constants include the elastic modulus (E) and Poisson’s ratio (ν) of ten different granitic rock were determined. By data analysis, correlations between Vp, Vs, E and ν with MGS and Qz/Fl were developed. It is concluded that the MGS and Qz/Fl have significant effects on the Vp, Vs, E and ν. Moreover, the results showed that MGS and Qz/Fl are in good accuracy for estimating the Vp, Vs and E, while there are no meaningful correlations between ν with MGS and Qz/Fl.
