“…The Aegean Sea and its surrounding area is one of the most rapidly deforming and seismically active regions in the Alpine-Himalayan mountain belt (e.g. Jackson, 1994;Taymaz, Jackson, & McKenzie, 1991), and the region is dominated by a series of E-W-, NE-SW-and NW-SEtrending horst and graben structures (Bozkurt, 2001;Kaymakcı, 2006;Koçyiğit, 2005;Koçyiğit & Deveci, 2007;Şengör, Görür, & Şaroğlu, 1985;Sözbilir, 2002). One of these structures is the DGHS, which is about 62-km-long and 7-28 km wide (Figure 1) (Koçyiğit, 2005).…”

“…The Honaz Fault Zone is a 15 km-long north-facing steplike normal fault that bounds the southern margin of the modern graben ( Figure 2) (Aydan, Kumsar, & Tano, 2005;Bozkuş et al, 2001;Gündoğan, Helvacı, & Sözbilir, 2008;Okay, 1989;Özkul et al, 2013;Koçyiğit, 2005;Kaymakcı, 2006). The northward arched structure exhibits prominent Quaternary fault scarps and significant morphological variations along the mountain front.…”

“…The uplifted and subsided blocks produced by normal faults in rift valleys exhibit remarkable geomorphic markers, and the use of quantitative measurements of features such as drainage systems, axial rivers, triangular facets and mountain front sinuosities play a prominent role in revealing tectonic activity in continental extensional provinces (Bull, 1977;Bull & McFadden, 1977;Gürbüz & Gürer, 2008;Keller, 1986;Keller & Pinter, 2002;Özkaymak & Sözbilir, 2012;Pérez-Peña, Azor, Azañón, & Keller, 2010;Ramirez-Herrera, 1998;Silva, Goy, Zazo, & Bardají, 2003;Viveen et al, 2012;Wells et al, 1988). Western Anatolia provides a natural laboratory for graben and horst morphology that has evolved since the early Quaternary (Bozkurt, 2001;Bozkurt & Sözbilir, 2004, 2006Koçyiğit, 2005;Koçyiğit, Yusufoğlu, & Bozkurt, 1999;Paton, 1992;Seyitoğlu, Tekeli, Çemen, Şen, & Işık, 2002;Sözbilir, 2001Sözbilir, , 2002Sözbilir, , 2005. A rift system that extends around Denizli in western Anatolia, known as the Denizli Graben Horst System (DGHS), is considered to be an actively growing rift system (Figure 1).…”

Honaz Dağı (Honaz Mountain, Denizli) is the highest peak in western Anatolia (2517 m) and represents the southern margin of the Denizli Graben Horst System in the western Anatolia Extensional Province. Honaz Fault is a 2-km-wide, 15-km-long northward arc-shaped dip-slip listric normal fault that bounds the northern margin of Honaz Dağı, and has been formed under an N-S-trending extensional tectonic regime since the early Quaternary. This study uses fieldwork and digital elevation model-based geomorphic analysis to identify the kinematic behaviour of the Honaz Fault. Morphometric indices, such as axial river profiles, drainage basin geometries, triangular facets, mountain-front lineament patterns and sinuosities, document the impact of active tectonics on the evolution of the Honaz Fault and its surroundings, as do valley floor width-to-height ratios and mountain front facet characteristics. These neotectonic indices suggest a relatively high degree of tectonic activity along the Honaz Fault, and suggest that the Quaternary landscape evolution of Honaz Dağı was governed by structural and climate-related erosional processes. Combined geomorphic indices and field data suggest that the analysed dip-slip normal fault segments of the Honaz Fault are linear and highly active, and could generate earthquakes with magnitudes of 6.7. Morphometric analyses of the fault trace along the mountain front yield minimum slip rates of .15-.38 mm/y for the Honaz Fault, which are similar to slip rates calculated for active normal faults in the Aegean region.

There, the horizontal components of intermediate and minor stress do not have a preferred orientation, indicating paleostress permutations (Homberg et al 1997), which is common in uniaxial stress conditions where magnitudes of two principal stresses are equal or close to equal (Kaymakci 2006 ).…”

Remains of fossil hominins from temperate regions of the Old World are rare across both time and space, but such specimens are necessary for understanding basic issues in human evolution including linkages between their adaptations and early migration patterns. We report here the remarkable circumstances surrounding the discovery of the first fossil hominin calvaria from Turkey. The specimen was found in the Denizli province of western Turkey and recovered from within a solid block of travertine stone as it was being sawed into tile-sized slabs for the commercial natural stone building market. The new specimen fills an important geographical and temporal gap and displays several anatomical features that are shared with other Middle Pleistocene hominins from both Africa and Asia attributed to Homo erectus. It also preserves an unusual pathology on the endocranial surface of the frontal bone that is consistent with a diagnosis of Leptomeningitis tuberculosa (TB), and this evidence represents the most ancient example of this disease known for a fossil human. TB is exacerbated in dark-skinned peoples living in northern latitudes by a vitamin D deficiency because of reduced levels of ultraviolet radiation (UVR). Evidence for TB in the new specimen supports the thesis that reduced UVR was one of the many climatic variables presenting an adaptive challenge to ancient hominins during their migration into the temperate regions of Europe and Asia.
