Fluorescent dye penetrants applied to rock fractures
Under ultraviolet illumination, nonparticulate fluorescent dye penetrants clearly mark surface traces of fractures in minerals and rocks; use of fluorescent penetrants has been effective in studying development of fractures in rock specimens deformed in laboratory; series of experiments concerned with studying generation and propagation of extension fractures in flexed specimens of porphyritic granite; photographs taken before and after deformation are presented and from these pattern of fracture development can be studied; fracture traces down to 0.05 mm wide have been observed and photographed.
