The Alanya Unit, consisting of three nappes, crops out in the Demirtas-Anamur area of the Tauride Belt and is related to the Alpine orogeny. The Mahmutlar nappe of Permian and pre-Permian age progressively evolved as indicated by 2M(t) white K-mica, Mg-chlorite, and 1M biotite which are related to increasing metamorphism from its upper (phyllite, metasiltstone) to lower parts (biotite schist, staurolite-kyanite-garnet-mica schist). The b values of the white K-micas are characterized by a facies series of medium- to high-pressure metamorphism. The Sugozii nappe comprises garnet-mica schist with metabasite (eclogite, glaucophane schist) interbands and/or lenses composed of muscovite, chlorite, and rarely paragonite and illite-smectite. The crystallinity and b values of phengitic micas in the metapelites represent epizonal and medium-pressure facies conditions. The Yumrudag nappe of Pre-Permian-Triassic age is characterized by index minerals, such as chloritoid, paragonite, kaolinite/dickite, 1Te pyrophyllite, and margarite. Epizonal 2M(l) white K-micas with low b values indicate lower-pressure metamorphism.
