Physico-chemical properties of the weathered Yazilikaya tuffs in Midas monument

The Midas monument is an impressive cult facade located to the south of Eskisehir province in Central Anatolia, Turkey. It is formed within Yazilikaya tuffs (white and pink). The tuffs of the Midas monument have deterioration problems. In this study, the depth and characteristics of the weathering zones developed within the white and pink tuffs rue investigated through thin section studies, the x-ray powder diffraction method, methylene blue adsorption tests, major element analyses, and some physical parameters. It is found that feldspar minerals are mechanically fractured due to weathering. The tuffs contain a small amount of clay minerals. The weathering of the tuffs produces weathered zones which are 4.5 cm thick within the white tuff and 2.5 cm thick within the pink tuff.

Characteristics of the weathering zones developed within the tuffs of the Midas monument
Topal, Tamer (2001-01-01)
The Midas monument, an impressive cult facade located in the southern part of the Eskiflehir provincein central Anatolia, Turkey, was made within tuffs (white and pink), which now have deterioration problems. Inthis study, the depth and characteristics of the weathering zones that have developed in the white and pink tuffshave been investigated through thin-section studies, X-ray powder diffractometry, methylene blue adsorption tests,major-element analyses, and some index parameters. It has been de...
Seismic Assessment of Monastery of Stoudios (Imrahor Mosque) in Istanbul
Kucukdogan, Bilge; Kubin, Josef; Ünay, Ali İhsan (2010-10-08)
Monastery of Stoudios, dated back to the reign of Eastern Roman Empire, is known to be the oldest surviving -albeit partially- religious building in Istanbul. During sixteen centuries, the building has been exposed to several earthquakes, fires and other minor disasters which have caused considerable damages and partial destruction in some of its sections. As a part of a general master plan for the structural condition assessment of historical buildings and monuments of Istanbul, this study aims to evaluate...
Durability assessment of some Cappadocian tuffs using factor analysis, multiple regression analysis, and analytical hierarchy process
Deniz, B. Ertas; Topal, Tamer (2022-01-01)
Tuff located in Central Anatolia (Cappadocia) has been used as a building stone in many historical monuments, churches, and mosques. Although some of the tuffs used in those historical structures show good performances, the others yield poor performances with their physical and mechanical properties varying in large ranges. This study aims to assess the durability of the tuffs using factor analysis (FA), multiple regression analysis (MRA), and analytical hierarchy process (AHP). In current study, thirteen t...
Determination of the rock mass characteristics and support systems of the new Ulus Tunnel, Ankara
Aksular, Irem; Doyuran, Vedat; Department of Geological Engineering (2008)
The New Ulus Tunnel will be constructed within the andesitic terrain at Hıdırlıktepe (Ankara). Excavation of the tunnel will be accomplished through blast and drill method. Emprical methods will be consulted during the design of the support systems as well as the slope of the portal rock face. Therefore it is essential to perform detailed rock mass characterization studies. In this thesis it is aimed to determine the rock mass characteristics in order to design the rock slope of the portals and to assess th...
Konya Alaeddin Camisi Yapım Evreleri Üzerine Düşünceler
Asutay Effenberger, Neslihan (Middle East Technical University, Faculty of Architecture, 2006)
The Alaeddin Mosque, which is located on a hill in the middle of modern Konya, is one of the most problematical monuments of the Seljuk Anatolia. It has suffered from several restorations and almost lost of its original substance. Its irregular prayer hall shows the following parts (from east to west): a hypostyle hall, a central unit with a mihrap cupola and a western wing. An U-shaped courtyard, where two kümbets are situated, is positioned in the north side of the prayer hall. In addition, some wall frag...
