This study is concerned with the geologic evolution of the Kayabuku (Selimiye) shear zone, Menderes Massif, Turkey. A geologic map between the towns of Milas and Yatagan was compiled from 1:25,000 scale previous geologic maps. 7 transects were made along the shear zone and 51 oriented rock samples were collected for microtectonic and petrographic analysis. Mesoscopic shear sense indicators were examined in the field.; Findings and conclusions. The Kayabuku shear zone separates orthogneiss in its footwall from schist and marble in its hanging wall. The first developed ductile shearing is top-to-the north, overprinted by top-to-the south ductile shearing which, in turn, is overprinted by top-to-the south brittle deformation. The hanging wall of the shear zone is locally brittlely deformed by a south-dipping normal fault zone, discontinuously exposed between the schist and marble units. Therefore, the shear zone must have been subjected to at least two deformation phases; D1: top-to-the north and D 2: top-to-the south. | Keywords/Search Tags: | Shear zone, Menderes massif, Top-to-the south | | Related items |
