“…It then divides into two branches: The Havri and Gezin Faults. The northern Havri Fault on which Çetin et al (2003) infer a 10-11 mm/year slip rate continues into Lake Hazar (Eris et al, 2017). The southern Gezin Fault on which earthquakes occurred in 1874 and 1875 is a normal fault, with a negligible strike-slip component.…”

“…The basin has been described as an active pull-apart basin (Şengör et al, 1985; Çetin et al, 2003). In the Quaternary, the western part of the lake was discharged by the Kürkçayı River and alluvial fans of diverse size extending parallel to the fault (Aksoy et al, 2007;Eriş et al, 2018a) (Figure 1b lower Cretaceous Guleman ophiolites, upper Cretaceous Elazığ magmatics, the Maastrichtian-upper Paleocene Hazar Group, the middle Eocene Maden Group, and Plio-Quaternary and Quaternary alluviums. Outcrops of the Elazığ magmatics and the Maden Group can be observed around the Kürkçayı River and in the vicinity of alluvial fans at the western part of the lake (Figures 1c and 2).…”

Mineralogical and geochemical analyses of samples collected from piston core HZ11-P01 at the western margin of Lake Hazar were studied to determine the provenance and weathering conditions on the source area together with tectonic setting of the source rocks, paleoclimate of the region, and paleo-redox conditions of the lake sediments. Nonclay minerals in the sediment core are represented by feldspar, quartz, dolomite, and calcite. The clay mineral assemblage consists of smectite/chlorite mixed-layer clay, chlorite, and illite. Most major, trace, and rare earth element contents of the lake samples are generally similar to those of the catchment area. Chondrite-normalized rare earth element patterns of the lake samples are characterized by enrichment of light rare earth elements, a relatively flat heavy rare earth element pattern, and no Eu negative anomaly. The chemical index of alteration and index of compositional variability of the core sediment suggested that the intensity of weathering in the source area was low to moderate. The paleoclimatic indicator (C-values) showed that a paleoclimate changing from semiarid to semimoist prevailed during the last ~2 ka BP. Authigenic U and element ratios such as Th/U, Ni/Co, Cu/Zn, V/Cr, Eu/Eu*, and Ce/Ce* indicate that the lake sediments were deposited under oxic conditions. La/Sc, Co/Th, Cr/Th, Zr/Sc, and Th/Sc element ratios in the core sediments are consistent with values of sediments derived from mainly mafic and intermediate source rocks. According to discriminant-function diagrams, lake samples are plotted within the arc setting and arc-continent collision, which is in accordance with the geology of the study area.

“…At the onset of the Bølling-Allerød (c. 14.6 ka BP) temperatures and moisture increased within a few decades to centuries (until 12.5 ka BP [34,35]), thus corresponding with a period of maximum humidity during the Late Glacial (14.9-13.5 ka BP [36]). In the later part of the Bølling-Allerød (13.5-12.9 ka BP) conditions became drier [36]. The subsequent Younger Dryas coincides with highest levels of aridity (c. 12.5-11.7 ka BP) and is consistently referred to as a cool and extremely dry period [34][35][36][37].…”

This contribution provides a first characterization of the environmental development for the surroundings of the UNESCO World Heritage site of Göbekli Tepe. We base our analyses on a literature review that covers the environmental components of prevailing bedrock and soils, model- and proxy-based climatic development, and vegetation. The spatio-temporal scales that are covered are mainly the Eastern Mediterranean region and the Late Quaternary—whereby special attention is given to available data from the close vicinity of Göbekli Tepe. Information on Late Quaternary geomorphodynamics is largely absent for the environs of Göbekli Tepe, we therefore included remote sensing data, different terrain modeling approaches and field-based geomorphological mapping to gain insights into past process dynamics. The findings indicate that the environmental conditions at Göbekli Tepe during its time of occupation differed significantly from today, showing denser vegetation and a wide spread sediment cover. Different hypotheses are developed that aim to guide future research on environmental changes and their variations during the Late Pleistocene and Holocene. These activities are crucial for a more profound understanding of the environment of the site, its potential perception by humans and therefore for the development of narratives on their landscape creation motives.
