Burdur Fault (BF) is located in Fethiye Burdur Fault Zone and it has formed in three main sections as Golbasi-Gokcebag, Burdur and Yassigume-cendik. The Neogene Basin is a NE-SW oriented depression basin which forms Plio-Quaternary aged lacustrine and alluvial deposits. Paleo-seismic structures on lacustrine sediments were studied with three excavation surfaces at the BF segments in Burdur settlement area. The relationships between different paleo-seismic structures were explained in detail. Although we have obtained new data for the timing of past earthquakes, it is to determine the shear rate of BF segments. Lacustrine sediments and alluvium sequences showing clear evidence of the shearing movement effects were observed. Studies on slopes of foundation excavations on BF segments and near the segment were investigated. Stratified lacustrine sediments observed, each of consisting thin clay layers which is weakly developed in the marl unit excavation surfaces near the Gokcebag segment. Thin layered lacustrine sediments developed that intersect with a parallel-parallel fractures that filled with collapsed sediments expose near the Burdur segment. In both excavation surfaces, the lower sedimentary unit is covered with a fine sand. The claystone and marl intercalations are discontinuous in the lateral direction and consist of alluvial and lacustrine deposits observed in excavation surfaces near the Yassigume-cendik segment. This study emphasizes that the importance of geological structure has a significant impact on the formation of fault segments.
