Deformation experiments under high static confining pressure and observations on tectonically deformed specimens have shown that orthoenstatite (space group Pbca ) can be transformed to clinoenstatite ( P 2 1 / c ) by shear stress. The specimen used for the present study was prepared by ion‐thinning from an orthoenstatite sample deformed at 800°C and 5 kb confining pressure at a strain rate of 10 −4 s −1 .
