Correlations of physical properties of rock and predictions of one property from a previously determined value of another property would expedite multiple site evaluation and selection programs, and possibly allow for reduction in the number of various tests required to determine the physical properties now deemed necessary for competent design and construction in rock media. This investigation was conducted to determine the influence of variation in grain size and minimal variation in rock type on the quality of rock property correlations for intact igneous rock types. Physical property tests were conducted on 79 cylinderical specimens of granite and tonalite representing 10 drill sites. Values of ultimate uniaxial compressive strength and static Youngs modulus of elasticity tangent were correlated with values of ultrasonic compressional pulse velocity, ultrasonic shear pulse velocity, ultrasonic Youngs modulus, ultrasonic shear modulus, ultrasonic bulk modulus, and ultrasonic Poissons ratio for each of the four following groups of specimens All tonalite specimens tested from the Sierra Nevada Batholith, California all tonalite specimens tested all granite specimens tested and, all specimens tested.
