FLUORESCENT DYE PENETRANTS APPLIED TO ROCK FRACTURES

UNDER ULTRAVIOLET ILLUMINATION, NON-PARTICULATE FLUORESCENT DYE PENETRANTS CLEARLY MARK THE SURFACE TRACES OF FRACTURES IN MINERALS AND ROCKS. THE USE OF FLUORESCENT PENETRANTS HAS BEEN EFFECTIVE IN STUDYING THE DEVELOPMENT OF FRACTURES IN ROCK SPECIMENS DEFORMED IN THE LABORATORY. THIS PAPER OUTLINES THE FLUORESCENT PENETRANT METHOD AS USED IN A SERIES OF EXPERIMENTS CONCERNED WITH STUDYING THE GENERATION AND PROPAGATION OF EXTENSION FRACTURES IN FLEXED SPECIMENS OF A PORPHYRITIC GRANITE. PHOTOGRAPHS TAKEN BEFORE AND AFTER DEFORMATION ARE PRESENTED, AND FROM THESE THE PATTERN OF FRACTURE DEVELOPMENT CAN BE STUDIED. FRACTURE TRACES DOWN TO 0.05 MM. WIDE HAVE BEEN OBSERVED AND PHOTOGRAPHED. THIS TECHNIQUE IS APPLICABLE TO OTHER ROCK TYPES IN A VARIETY OF LABORATORY SITUATIONS, AND ITS POSSIBLE USE IN SITU STUDIES IS NOW BEING INVESTIGATED. /AUTHOR/
