Abstract

Elmalı Basin, which consists of the Elmalı county and some villages, approximately 120 km far from Antalya city, is one of the recent depositional areas in the extensional neotectonic region of southwestern Turkey. The basin provides signifi cant data for the understanding of the geological evolution to record from the basement to recent depositional units. For this reason, these kinds of structures are used to determine the deformations phases for the evolutionary history of basin formation. In the content of the study, following applications have been investigated: (a) mapping of the area and structures in 1/25.000 scale, (b) information about deformation and tectonic activity along the basin margin faults, (c) the distribution of peak ground acceleration (PGA) in case of an earthquake with 6.5 magnitude and (d) morphometric analyzes of the basin to understand the tectonic uplift by using the digital elevation model. The new results combined with existing data imply that the Elmalı Basin has a number of deformation structures and active faults on both western and eastern sites of the basin. Depending on the morphometric indices, western side of the basin created higher uplift ratio compared with the eastern side of the basin.
