Abstract
Bronzite in a highly deformed and partially metamorphosed gabbro from Central Australia shows intensive bending and kinking. The optical properties of some kinked and deformed areas differ significantly from those of the original bronzite. Single crystal X-ray and optical investigations show that some highly strained areas of bronzite have inverted to clinoenstatite (2V=50±6°; sign +;ZΛc=32±2°). Mixed phases of both also occur. The new clinoenstatite lattice is untwinned.
