The Simav Graben: An example of Young E_W Trending Structures in the Late Cenozoic Extensional system of Western Turkey

Authors: Gürol SEYİTOĞLU

Abstract: The Simav graben is a Pliocene(?)-Quaternary structure which clearly cuts NE-SW trending Demirci, Selendi and Akdere basins. The south side of gra34ben is bounded by the north dipping Simav fault. Corrected epicentre locations and fault plane solutions of the 1969.3.23 Demirci eartquake demonstrate that the Simav fault was recently active and has a listric shape. The graben is regarded as one of the latest products of N-S extensional tectonics which began to affect the Aegean region in latest Oligocene-early Micene time.
