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 for- mation. 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 tec- tonic 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 Received Date: 09.12.2016 eastern sites of the basin. Depending on the morphometric indices, western side of the basin created Accepted Date: 28.09.2017 higher uplift ratio compared with the eastern side of the basin. 1. Introduction why the study area is in the II. Degree earthquake zone. The most critical point here is that there is no The study area Elmalı basin and its near vicinities detailed investigation in the study area up to now and is the recent depositional area inside the border of probably many geological data are expected to be Antalya city (Figure 1). In the regional aspect, the available because of the existence of recent deposits. area is located on a controversial area where the Eventually, both the recent sedimentation features and evolution of Taurus and Isparta Angle have different the existence of deformation structures indicate some geological history, the initiation of recent tectonic clues the necessity of detailed investigation in the area regime and type of tectonic regime. As it is known during the fi rst fi eld excursion. from the principals, recent depositional areas are the main target to investigate the tectonic records. In order In this research, three main objectives are to understand the recent tectonic and deformational considered. First one is the stratigraphic and tectonic structures, previous discussions are also summarized characteristics of the basin fi ll. 1/25.000 scaled briefl y. geological map of the study area containing the unit boundaries, boundary relations and deformation Although the Elmalı basin is located on the II. structures are examined and mapped.

The Elmalı Basin is a recent depositional area Moreover, Isparta Angle is issued for controversy located in the western wings of Isparta Angle, within about the initiation age of the neotectonic period the western Anatolian extensional neotectonic region. and the type of recent tectonic regime. A group of Due to its location and current position, it has great scientists think that this structure is still active and importance to understand the geological evolution of deformed by compression regime (Akay and Uysal, the region (Figure 1). 1988; Boray et al., 1985; Barka et al., 1995; Yılmaz et al., 2000; Poisson et al., 2003; Kelling et al., 2005; Studies involving the structural data of the Alçiçek et al., 2006), on the other hand others argue neotectonic period around Elmalı and its vicinities that it is under the control of the extensional tectonic are very limited in the literature. In addition, there regime characterized by normal faults (Koçyiğit, are
