The following figure shows various metamorphic facies in P-T space (numbered as domains I to X). In this figure, name the domains and the corresponding facies in which the following two mineral assemblages would stabilize by metamorphism of basic rocks: (lawsonite + jadeite) & (prehnite + pumpellyite). Which domain and corresponding facies will NOT contain plagioclase feldspar in metamorphosed basic rocks? Explain why. Temperature ("C) 00 200 u 400 S00 600 700 800 9 VIl VITI 6 8
