ABSTRACT:
A confining pressure system includes a pressure cell containing a mechanical oscillator and a gas supply for carrying out resonance measurements of rock material under confining pressure at seismic frequencies. An appropriate gas is used to avoid significant damping of oscillations under confining pressures of various ranges.
