Eastern Mediterranean continental collision: The role of the Fethiye-Burdur fault zone in the neotectonic evolution of SW Turkey

在这一更新建议中，我们描述了土耳其西南部Fethiye-Burdur断裂带（FBFZ）南部Esen盆地综合盆地分析的第一个结果。本研究从不同的观测时间尺度，即地质、历史和现代时间尺度，寻求与断层有关和与地震有关的变形。我们使用构造沉积记录来定义变形阶段，并应用断层运动学分析来推断古应力场。高分辨率激光雷达测量可以维持希腊-罗马剧院中损坏结构的考古地震清单。获得的剧院三维数字模型可以使用各种空间分析程序测量和计算其亚厘米尺度的变形（例如倾斜、错位、裂缝）。地质探地雷达剖面进一步证实了活动断层的存在，显示了最年轻第四纪冲积层的断层偏移。正在进行的研究活动集中在探地雷达剖面中探测到的断裂带的古地震沟。最后，所有的应变数据将结合起来，并与当前的板块构造模型进行测试，并辅以GPS建模方法，使基于现场的构造（应变）模型能够得到验证。结果将提高对这一重要地区构造复杂性的理解，对板块边缘变形过程的见解和一般的高社会相关性（地震风险评估）具有特定的意义。

In this renewal proposal we describe the first results of an integrated basin analysis of the Esen Basin in the southern part of the Fethiye-Burdur Fault Zone (FBFZ) in southwestern Turkey. This research seeks for faulting-related and earthquake-related deformation from different observational time scales, i.e., the geological, historical and present-day time scales. We use(d) the tectonosedimentary record to define deformation phases and applied fault kinematic analysis to deduce paleostress fields. An archeoseimsological inventory of damage structures in a Hellenistic – Roman theatre could be sustained by high-resolution LIDAR measurements. The obtained 3D digital model of the theatre enables measuring and calculating – using various spatial analysis programs – its deformation (e.g. tilting, dislocations, cracks) on sub-centimetre scale. The presence of active faults could be further established with GPR profiling, showing fault offsets in the youngest Quaternary alluvium. Ongoing research activities focus on paleoseismological trenching of the fault zones that were detected in the GPR profiles. Finally all strain data will be combined and tested against the present-day plate-tectonics models, supplemented with a GPS modelling approach that enable validation of field-based tectonic (strain) models. The outcome will improve the understanding of the tectonic complexity of this important region, has specific implications for insights in plate-margin deformation processes and a high societal relevance (earthquake risk assessments) in general.
