Based on both the detailed field and laboratory studies carried out at the north of Ankara., northwest of Amasya and south of Tokat in northern Turkey., the presence of remnants of different types of forearc .basin at the active margin of Northern Neo-Tethys has been found. The forearc deposits exposed at these localities are underlain either by only subduction complex which is coloured ophiolitic melange named as the Anatolian Nappe., or by both older rock assemblages named as the Karakaya Nappe and the Anatolian Nappe. Based on the bottom boundary relationships of the forearc sequences., the forearc basins observed in northern Turkey are of t,vo main types., namely., accretionary and constructed forearc basins. On the other: ha~d., the p'~le~n:t~i~gi~~id~ta eoming from the lowermost part ~{' th; forearc basin sequences suggest that the deve~opment ag~ of the Anatolian Nappe as.. a subduction .,complex at .the active margin is preMiddle Campanian. However., its emplacement age on the passive continental margin ranges in Late Maastrichtian to Late Pliocene time interval

The Upper Cretaceous intrusive rocks with extensive crustal contribution in Hacimahmutusagi Area (Aksaray/Turkey) Köksal, Serhat (Central Library of the Slovak Academy of Sciences, 2019-06-01) The Hacimahmutusagi area (Aksaray/Turkey) is located in the western part of the Central Anatolian Crystalline Complex (CACC). Gneiss and marble compose the basement units, while intrusive rocks are gabbros and granitoids. The pegmatitic hornblende gabbros contain pegmatitic to fine-grained hornblendes, plagioclase, clinopyroxene, and accessory opaque minerals. The fine-grained gabbros, on the other hand, are composed of plagioclase, hornblende, and biotite as major components whereas the apatite and opaque ...
An analysis of the thermal performance of METU staff housing units and calibratıon of their simulated model Bağcı, Mediha Özlem; Elias Özkan, Soofia Tahira; Department of Architecture (2008) The aim of this study was to investigate the thermal performance of residential units in the Middle East Technical University (METU) Campus, Ankara. The study was conducted on the unoccupied residential units to eliminate the occupant interventions. There were only three unoccupied residential units in the study period, hence sample was considered as randomly selected. Case study units were triplex row houses and all physical characteristics were identical apart from their orientations. The thermal performa...
Main seismological features of recently compiled Turkish strong motion database Erdoğan, Özgür; Akkar, Sinan D.; Department of Civil Engineering (2008) In this thesis it is aimed to compile the Turkish strong-motion database for its efficient use in earthquake engineering and strong-motion seismology related studies. Within this context, the Turkish strong-motion database is homogenized in terms of basic earthquake source parameters (e.g. magnitude, style-of-faulting) as well as site classes and different source-to-site distance metrics. As part of this objective, empirical relationships for different magnitude scales are presented for further harmonizatio...
Major and rare earth element contents in sedimentary rocks of the Haymana formation, Ankara, Turkey KOÇ, ŞÜKRÜ; SARI, ALİ; Cimen, Okay (2016-01-01) The study area is located 4 km east of Haymana, Ankara, Turkey. Major and rare earth element (REE) contents in samples collected from siltstone, carbonaceous claystone, and marl of the Haymana formation in the studied region and their distribution with respect to lithology and correlation relations yield important data on the evaluation of forming conditions of basin. Regarding the abundance of elements in various lithologies, the first and second group elements (SiO2, Al2O3, Na2O, TiO2, P2O5 and Fe2O3, K2O...
Calibration of a grate on a sloping channel Sipahi, Sabri Özgür; Tiğrek, Şahnaz; Department of Civil Engineering (2006) In this study a setup is designed and constructed in the Hydromechanics Laboratory of Middle East Technical University in order to observe the flow through grate inlets under different flow and geometry conditions. The rate of interception of flow is determined over a rectangular channel through preliminary experiments run on the tilting flume. The performance of the new set setup has been examined and grate efficiency is obtained both in terms of longitudinal slope and the Froude number. The results which ...
