“…Because precipitation with lower δ 18 O values owing to the presence of orographic rainout eventually ends up in lake waters, the development of a rain shadow may be reflected in δ 18 O reconstructions of lacustrine sedimentary rocks. In Anatolia, we can observe the emergence of a rain shadow in the significantly lower δ 18 O values of Cappadocian Pliocene lacustrine sedimentary rocks [ Göz et al ., ] that overlay higher values in Oligocene to Upper Miocene (lower Tortonian) carbonates [ Lüdecke et al ., ; Mazzini et al , ]. These isotopic changes likely reflect the effect of the uplift of the Tauride and Pontide mountain belts after ∼8 Ma [ Yıldırım et al ., ; Schildgen et al ., ].…”

The age and paleoenvironmental record of lacustrine deposits in the Aktoprak basin of south-central Turkey provides information about the evolution of topography, including the timing of development of an orographic rain shadow caused by uplift of the mountain ranges fringing the Central Anatolian Plateau. New magnetostratigraphy-based age estimates, in combination with existing biostratigraphic ages, suggest that the partially remagnetized Kurtulmuş Tepe section of the basin is Chattian (Upper Oligocene). The mean carbon and oxygen stable isotope ratios (d 18 O5 24.6 6 2.0 &, d 13 C5 24.9 6 1.1&) are largely constant through the section and indicative of a subtropical, open freshwater lake. These isotopic values are also similar to those of the Chattian Mut basin to the south, on the Mediterranean side of the modern orographic barrier (Tauride Mountains), and indicate absence of an orographic barrier during Late Oligocene basin deposition. Post-depositional partial remagnetization occurred after tilting of the basin sequence and was mineralogically controlled, affecting grey, carbonate-rich rocks (average %CaCO 3 5 82), whereas interlayered pink carbonate-poor rocks (average %CaCO 3 5 38) carry a primary, pretilt magnetization. The pink rocks are rich in clay minerals that may have reduced the permeability of these rocks that carry a primary magnetization, concentrating basinal fluid flow in the carbonate-rich grey layers and leading to the removal and reprecipitation of magnetic minerals. The normal and reverse polarities recorded by the remagnetized rocks suggest that remagnetization occurred over a protracted period of time.

Micro‐Raman And Micro‐Stratigraphic Analysis Of The Painting Materials In The Rock‐Hewn Church Of The Forty Martyrs In Şahinefendi, Cappadocia (Turkey)

This paper presents the results of analyses carried out on the paintings on the rock‐hewn walls of the Forty Martyrs church at Şahinefendi in Cappadocia (a UNESCO World Heritage Site), a central region of Turkey, performed during conservation work from 2007 to 2012. The micro‐samples were investigated by spectroscopic, micro‐stratigraphic and scanning electron microscopy analysis in order to study the painting technique, the materials and the degradation products. The micro‐stratigraphic analysis showed a white, sometimes pinkish, plaster. Micro‐Raman analysis, performed on cross‐sections of the mortars, enabled the detection of calcite, gypsum, anhydrite and calcium oxalate. Scanning electron microscopy and energy‐dispersive spectroscopy revealed a similar composition among all investigated phases, aside from minor differences such as the presence of diatoms in the second and third phases and of biotite, lime lumps and plants fragments in the fourth one. Apart from traditional pigments of medieval wall paintings, micro‐Raman analysis revealed the presence of lead‐based compounds and jarosite.

ÖZNevşehir ili, Tahar ve Güzelöz yörelerinde geç Miyosen-erken Pliyosen yaşlı volkanosedimenter birimler içerisinde yeralan diyatomitlerden biri Tahar yöresinde (geç Miyosen yaşlı Ürgüp Formasyonu'nun Bayramhacılı Üyesi içerisinde), ikisi Güzelöz yöresinde (erken Pliyosen yaşlı Ürgüp Formasyonu'nun Kışladağ Üyesi içerisinde) olmak üzere ölçülen stratigrafık kesitlerden 21 diyatom cinsine ait 73 tür tanımlanmıştır. Tanımlanan diyatom cins ve türlerinin 20 mikroskobik slayt alandaki bolluk dağılımları dikkate alınarak, inceleme alanındaki diyatomitlerin paleoekolojik özellikleri yorumlandığında; her üç lokasyonda diyatomitlerin oluşumu sırasında göl suyunun nötr ve asit özellik gösterdiği, Tahar ve Güzelöz-2 lokalitelerinde diyatomitlerin oluşumu sırasında göl suyunun tatlı su özelliğinde olduğu, Güzelöz-1 lokalitesinde ise tatlı su özelliğinde başlayıp, tavana doğru acı su özelliğine dönüştüğü, Tahar lokalitesinde (geç Miyosen); göldeki su seviyesinin ve su sıcaklığının yüksek olduğu, göl tabanında çamur bulunduğu, göl suyunun besin oranının başlangıçta düşük-orta başlayıp, tavana doğru ise arttığını, göl suyunun oksijen oranının başlangıçta yüksek, daha sonra orta seviyede bulunduğu, Güzelöz-1 (erken Pliyosen) lokalitesinde; göldeki su seviyesinin ve besin oranının değişken olduğu, göl tabanınında bitkilerin bulunduğu, su sıcaklığının başlangıçta düşük, daha sonra yüksek olduğunu, göl suyunun oksijen oranının başlangıçta yüksek, daha sonra orta seviyede bulunduğu, Güzelöz-2 (erken Pliyosen) lokalitesinde; göldeki su seviyesinin, su sıcaklığının ve besin oranının yüksek olduğu belirlenmiştir. ABSTRACTSeventy-three species of 21 different diatom genera were identified from three stratigraphic sections which are located in the late Miocene-early Pliocene volcanosedimentary units in Tahar and Güzelöz (Nevşehir) areas. One of these sections was measured in the Tahar area (in the late Miocene age Bayramhacılı Member of Ürgüp Formation), and the two sections were measured in the Güzelöz area (early Pliocene age Kışladağ Member of Ürgüp Formation). When evaluated of the investigated area diatomite's palaeoecological properties by considering the distribution of numerical values (in 20 microscopic slide area) of the determined diatom genus A. GÜNEY, A. GÜREL, E. OKUR 256 and species; It have been determined that, when the formation of the diatomite at all three locations, the lake water has neutral and acid properties. At the Tahar and Güzelöz-2 locations the lake water was fresh water feature, also, in the Güzelöz-1 location the lake water was initially as fresh water feature and than changed to bitter water character towards to top of the section. At the Tahar location (late Miocene); lake water's level and temperature was high, the bottom of the lake was muddy. The nutrient ratio of lake water was initially lowmoderate, later increased towards to top of the section. Lake water's oxygen ratio was initially high, later in the middle level. At the Güzelöz-1 location (early Pliocene); lake water's level and nutrient was va...
