Özet

In the Söke-Kuşadası Neogene succession, three major tectono/stratigraphic units may be distinguished; the lower unit, resting on the high grade metamorphic rocks of the Menderes massif, outcrops near the Söke town. At the base it consists of a fault-scree deposits and fluvial conglomerates, formed in front of a NE and NW trending transtensional, conjugated strike-slip fault zones, which were developed in an approximately N-S compressional deformation.

The coarse elastics pass upwards into fine-grained lacustrine rocks, dominated by marls and shales of lower to middle Miocene in age. The rocks were deformed by N-S compressional deformation. A new basin began to develop along N-S direction, during the late Miocene, rupturing the lower to middle Miocene sediments. The clastic rocks of this basin is delimited by the fault, bounded the uplifted blocks. The elastics pass northwards into widespread lacustrine deposits, which extends into the off-shore Aegean Sea. The present EW fault system is young. They cut the Miocene successions, and form the E-W elongated Dilek peninsula. The tectono-morphological evidence suggests that the present grabens post dates the Miocene basin sediments, and has formed during Pliocene-Pleistocene
