806078 ROCK IDENTIFICATION BY MEANS OF CONTINUITY INDEX

(IN ~ N ~ ) Denis, A; Panet, M; Tourenq, C Proc 4th Congress International Society for Rock Mechanics, Montreux, 2-8 Sept 1979, Vol 2, P95-96. Publ Rotterdam, A A Balkema,

1979 The Continuity Index is based on the measurement of sound velocities in rocks. Its determlnation makes possible quantitative approach of the rock fissuration state. The authors recommend an extensive use of this quick and non destructive determination for rock identification. Auth.
