NEW SHEAR APPARATUS FOR TEMPERATURES OF 1000 C AND PRESSURES OF 50 KB,

Abstract

A new shear press, capable of simultaneous presures and temperatures of 50 kb and 1000 C, incorporates a 5-k2 high frequency induction heater, 300-ton hydraulic jack, 1/2-hp motor and 3-pinion gear train for strain rates of 0.01 to 10 rph, and tungsten carbide ball-type anvils faced to diameters of 1/4 in. to 1 in. The press, designed to simulate earth depths of 30 to 200 km, determines shear strength, viscosity, and internal friction data for rock samples of lower crust and upper mantle composition under geophysically realistic conditions of temperature and pressure.
