The laboratory measurements of physical properties such as density, porosity, ultrasonic P-wave and S-wave velocities, Poisson’s ratio, Young’s modulus, Bulk modulus, and Shear modulus have been carried out of some of the different types of rocks of southern part of geographical Indian sub-continent. The rock samples consisted of igneous, sedimentary and metamorphic origins like basalt, granite, sandstone, rhyolite, dolerite and granulite. The dynamic elastic moduli were calculated using density, P-wave and S-wave velocity data’s. The compressional P-wave and shear S-wave velocities increases with increase in density, young’s modulus, shear modulus and Bulk modulus. Based on observed experimental results the rock samples which can be classified under excellent quality rocks are NK19AY2 (Granulite) and JDP-20B (Sandstone) can be classified under good quality rocks for engineering applications
