Abstract

In the Entia Dome of the eastern Arunta Inlier kyanite-facies metamorphism is recorded over a substantial area (at least 160 km2) and thus contrasts with the regionally extensive belts of high-temperature-low-pressure andalusite-sillimanite facies metamorphism documented elsewhere in the Arunta Inlier. This amphibolite facies event appears to postdate regional granulite facies metamorphism, evidence for which is almost totally obliterated. In the Entia Dome prograde kyanite occurs in meta-basites in comparatively rare associations involving hornblende, staurolite and anorthite, and in other rocks in association with gedrite and hornblende or garnet and biotite. These kyanite-bearing assembla..
