This study is concerned with the Pb-isotope compositions of galena samples from Pb-Zn occurrences in southern Turkey. The purpose is to i) provide chronologic information for ore deposition, ii) investigate the likely source(s) of lead in ore deposits, and iii) examine the possible control of tectonic setting and crustal basement on Pb-isotope compositions. The data used in the study belongs to the deposits located in Taurides (Zamanti, Kahramanmaras, Malatya, Elazig, Bitlis), with additional data from Nigde Massif and Hakkari Area. The mineralizations are dominantly carbonate-hosted Pb-Zn deposits formed as fracture and karst fillings and, in some places, parralel to bedding. Ore minerals are mainly Zn-oxides and minor Zn, Pb-sulphides. The Pb-isotope compositions, as evaluated in terms of their configuration with respect to reference crustal growth curves and reference isochrons on conventional Pb-isotope diagrams, point to U/Pb ratios greater than average crustal values (and close to the Western Mediterranean Crustal Growth Curve) for all the deposits, indicating upper crustal source for Pb. However, some of the deposits (Afsin-Kahramanmaras; Oreks, Dündarli, Agcasar and skarn type deposits to the south of Çadirkaya in Zamanti (Kayseri-Adana); Keban-Elazig) appear to have magmatic inputs in their genesis. Relatively old deposits are likely Paleozoic (Cafana-Malatya and Türksevin-Kahramanmaras), Late Paleozoic-Early Mesozoic (Kaleköy-Zamanti) and Mesozoic (Hakkari) in age. The rest of the deposits (most of the occurrences in Zamanti, Nigde, Kahramanmaras, Elazig and Bitlis) are likely of Cenozoic age. The Pb-isotope compositions are, in general, similar to those from other occurrences in the

Ionic composition of aerosols at Northwestern Turkey Tokgoz, Deniz D. Genc; Dogan, Guray; Ilhan, Ali Ihsan; Balta, Tulay; Tuncel, Süleyman Gürdal (2015-01-01) In this study, ionic compositions of 350 aerosol samples collected between April 2006 and May 2008 in a rural area at Northwestern Turkey (Black Sea coast of Turkey) were discussed. Ions accounted for approximately 30% of PM mass. Contributions of secondary aerosol species (NO3-, SO42- and NH4+) were higher than the ions with crustal origin. This indicated that sampling station was under the influence of long range transport because there were no industrial emissions around. Concentrations of ions demonstra...
Spatial distribution of some elements and elemental contamination in the sediments of Koycegiz Lake (SW Turkey) Gulsen-Rothmund, Halil Ibrahim; Avsar, Ozgur; Avşar, Ulaş; Kurtulus, Bedri; Tunca, Evren (Springer Science and Business Media LLC, 2018-07-01) Elemental accumulation, distribution and relationship profiles for sediment samples taken at 81 localities in the Koycegiz Lake were investigated. Spatial distribution maps for ten elements (Cu, Pb, Zn, Ni, Cr, Co, Mn, Mo, Al, Fe) were created using the ordinary kriging interpolation method. Statistical tests revealed that the sediments taken from areas close to the Namnam (NamSM) and Kargicak (KarSM) stream mouths have the highest element content. In addition, sediments close to NamSM have the highest cont...
Integration of Surface Wave Seismic Survey Testing Results and Segmented Seismic Source Model of NAFS for PSHA of the Gölyaka Düzce Tectonic Basin Turkey(2005) Yousefibavil, Karim; Akgün, Haluk; Eker, Arif Mert; Cambazoğlu, Selim; Koçkar, Mustafa Kerem (null; 2015-11-04) This study mainly focuses on the determination of site effects for the Plio-Quaternary sediments of Gölyaka-Düzce, Turkey by characterizing local soil conditions. Probabilistic seismic hazard assessment (PSHA) analysis was performed to observe the effect and importance of local site conditions. The study area is located within the Eastern Marmara Region and uniquely falls within the bifurcated section of the North Anatolian Fault System (NAFS). This tectonic basin is bounded by the surface rupture of the 19...
Heavy Metal Contamination Analysis of Bottom Sediments of Köycegiz Lake and Fethiye-Göcek Bay, SW Turkey Gülşen Rothmund, Halil; Avşar, Özgür; Avşar, Ulaş; Kurtuluş, Bedri; Tunca, Evren (null; 2018-04-13) In this study, the heavy metal contamination in the base sediments of Köyceğiz Lake and Fethiye-Göcek Bay in Muğla, Turkey was assessed. The focus lies mainly on Mo, Cu, Pb, Zn, Ni, Co, Mn, Fe, As, Cr and Al metals. The applied analysis methods on the data set of 150 sediment samples (81 samples in Köyceğiz Lake and 69 samples in Fethiye-Göcek Bay) are the following: contamination analyses (contamination factor, contamination degree, modified contamination degree, enrichment factor, geo-accumulation index, ...
SIMILARITIES AND DIFFERENCES IN COMPOSITIONS OF EASTERN AND WESTERN BLACK SEA AEROSOL Balcılar, İlker; ZARARSIZ, ABDULLAH; KALAYCI, YAKUP; DOĞAN, GÜRAY; Tuncel, Süleyman Gürdal (2017-01-01) In this study daily aerosol samples were collected at two different sampling stations at the Black Sea Region of Turkey. Western Black Sea sampling station is located at the Bulgarian border of Turkey and approximately 50 km from the Black Sea coast. The station on the Eastern Black Sea is located at a high altitude site which is approximately 75 km from the Black Sea coast. Both stations are situated at relatively remote rural locations. Nearest large settlement area is at least 50 km away from both sites....
