Kinematic characteristics of metamorphic rocks located in the northeast of Gördes (Manisa)

In this study, the kinematics and geological setting of the metamorphites in the northeast of Gördes (Manisa) were investigated. The Menderes Massif, represented by gneiss orthogneiss-migmatites, forms the base of the study area. The Menderes Massif metamorphics are overlain by ophiolitic rocks with a low-angle tectonic contact in the east of the study area. The tectonically emplaced nappes have led to the development of ductile secondary structures in the rocks of the Menderes Massif. These secondary structures observed in the metamorphites include stretching lineations and foliations, outcrop and micro-scale shear band cleavages and asymmetric deformed minerals. The evaluation of the defined kinematic data reveals that the nappe overlying the Menderes Massif moves towards the northeast. It was determined that the ductile deformation phase was related to the Alpine orogeny and the brittle deformation phase which cut the ductile structures was represented by high-angle faults in the Neotectonic period.
