It has recently been suggested by Camacho et al. (2005) that the granulite facies anorthosites, remained at low temperatures (350°C) and were only locally heated to 700°C and reacted to eclogites by spasmodic hot fluids. This is in contrast to previously published models (Austrheim 1987) where the fluid-triggered mineral reactions in a terrain that was at 700°C during the Caledonian Orogeny. In the latter model the dry granulites metastably survive the Caledonian HP/HT metamorphic event at 425 Ma...}, note = { \url {http://hdl.handle.net/11858/00-1735-0000-0001-3418-1}}, }
