Metamorphism in Northern Part of Menderes Massive, Turkey (Ödemiş-Bayındır-Turgutlu Region) Some Rare Mineral Paragenesis.

Abstract: In this study, characteristics conditions of metamorphism in the metamorphic series around Ödemiş-Bayındır-Turgutlu region (northern part of Menderes Massive, Western Turkey) has been investigated usingtypical index minerals.The area consists mainly of sericite-chloride quartzites, schists biotite-garnet schists, calc schists, kyanite -staurolite schists, amphibolites, gneisses, marbles belonging to greenschists, amphibolite facies a third transitional facies between the two.Metamorphic conditions estimated to vary between 3.5-6.5 kbar 4(KL700°C. Geological petrographical workshows the presence of migmatites partial anatexitic rocks outcropping at different parts of the study area.Four different occurences of silUmanite has been found in four different, localities. Rather rare andalusite-staurolite-chloritold andalusite-staurolite paragenesis occur in the northwest part of the massif.
