Abstract
The Pan-African high-pressure (8–10 kbar) granulite facies metamorphism in Tanzania is characterized by relatively uniform conditions over large distances and an anticlockwise P-T path. The latter is interpreted as the result of magmatic underplating causing heating during crustal thickening. In contrast, the Usagaran along the southeastern border of the Tanzania Craton contains eclogitic rocks (10.5–14.7 kbar) characterised by a clockwise P-T path due to tectonic crustal thickening, followed by erosion and uplift.
