“…Investigations (Vettegren' et al, 2011a(Vettegren' et al, , 2012a(Vettegren' et al, , 2012b(Vettegren' et al, , 2014 showed that the determination of quartz nanocrys tal size in rocks is conveniently done by using the results from the analysis of the shape of the band whose maxi mum in the reflection spectrum is at 693.4 cm -1 . The ATR spectra (see Fig.…”

This study is concerned with the glide plane that is produced during a dynamic fracture in a rock mass and with the section that is perpendicular to the plane. The techniques that were used include X ray, infrared, and fluorescent spectroscopy. It was found that the plane consists of quartz and albite nanocrystals surrounded with water that contain numerous defects, viz., "broken" chemical bonds and admixture atoms. The formation of such a structure seems to have reduced the friction coefficient and produced conditions for the development of an unstable slip in the rock mass.
