Abstract
RECENT developments in structural mapping in the Dalradian rocks of Scotland have led to the re-interpretation of regional metamorphism and recognition of its phase-by-phase development1–5. In this respect, textural studies have proved particularly useful in so far as relict textures are preserved as inclusions within porphyroblasts, thus permitting a recognition of fabrics6, which in the rock as a whole, owing to subsequent recrystallization, have disappeared. In the middle-grade zones of regional metamorphism of Dalradian rocks, garnet porphyroblasts are particularly abundant, and their inclusions can be grouped into the pre-porphyroblast, the syn-porphyroblast and the post-porphyroblast.
