Summary

The directional variation of ultrasonic velocity has been studied in some of the Indian rocks. Quartzites and Marbles which are monomineralic show almost perfect isotropy. Granite shows a slight departure from isotropy (5 to 8%) which is attributed to the variation in mineralogical composition and in grain size from direction to direction.
