Özet

The Anamur region in the eastern part of the Alanya Massif is defined by high temperature metamorphism. Metamorphic rocks (Sariagac unit), under the conditions of the upper amphibolite facies which are interrupted by basic and acidic meta-magmatics in the region, constitute the para-autochtonous basis. Kapidag nappe, has undergone metamorphism the Barrow-type medium-pressure metamorphism in the greenschist facies is overlain by the tectonic contact of the Sariagac unit with the ductile conditions. The Kapidag nappe, which forms a regular and thick sequence, begins with a probable infra-cambrian aged assemblage in the base consisting of dolomite, marble, muscovite-quartz schist and chlorite schist alternation. This assemblage is overlain by low-grade metamorphics of Tauride units consist of quartzite, meta-carbonate and schists derived from Hudai, Caltepe and Seydisehir formations in Cambro-Ordovician aged. All these metamorphic units are unconformably overlain by conglomerates belonging to Late Eocene-Oligocene Anamur Formation and then Hadim nappe thrusted over to all units.
