Rock Deformation at High Confining Pressure and Temperature.

Abstract

A triaxial rock deformation apparatus capable of generating confining pressures to 10 kb and temperatures to 1000C has been built, calibrated, debugged, delivered and installed to the contracting agency. Clay specimens of illite, kaolinite and montmorillonite were deformed in tri-axial compression at 25 and 3000C at a constant confining pressure of 2 kb and a constant strain rate of .0001 sec. The illite and kaolinite are stronger under these conditions than montmorillonite. Cores from dolomite single crystals were deformed at a confining pressure of 7 kb and temperatures of 300 and 500C. The dependence of intracrystalline slip on temperature has been documented. (Author)
