ANALYSIS OF THE STATE OF RESIDUAL ELASTIC STRAIN IN GUARTZOSE ROCKS BY X-RAY DIFFRACTION

The residual elastic strain in an oriented quartzite sample taken from outcrop is measured by means of x-ray diffraction. Two disks cored at right angles to each other are cut parallel to the XY plane and the Z axis respectively of a rectangular coordinates system related to the field orientation. Six solutions for the principal strain axes are calculated by computer analysis. The technique permits a general solution of the three- dimensional state of residual elastic strain in naturally deformed rocks. /FHWA/
