Analysis of the State of Residual Elastic Strain in Quartzose Rocks by X-Ray Diffraction.

摘要

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 coordinate 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.
