Kyanite is considered to have been the stable Al2SiO5 polymorph during Badcallian metamorphism in both the Stoer and Scourie areas of NW Scotland. T estimates of 900-1000oC for these areas imply minimum P of 12-14 kbar. Crustal thickening sufficient to give such P is known from the Alps and Himalayas; the rocks of the Scourie complex may have formed in a similar environment. - R.A.H.
