The Hasankeyf Antique City located in southeastern Anatolia (Turkey) includes several historical heritages and man-made caves. It is mainly located in dolomitic limestone. The city will be partly under water after reservoir impounding of the Ilisu dam, and the limestone will be subjected to cyclic processes such as wetting-drying and freezing-thawing. Although a new town is formed and part of the city is transported to a nearby area, this cannot be done for many existing historical and cultural values at the site. The behavior of the limestone under cyclic processes is not known. In this study, deterioration mechanisms of the limestone were investigated with field and laboratory studies. It is found that the rock is not durable. Very thin surficial deterioration zone exists on the rock surface. Discontinuity-controlled block failures associated with collapse of man-made caves occur at the site before reservoir impounding. Further discontinuity-controlled block failures are expected to occur after reservoir impounding by aggravated deterioration and surface erosion of the rock within the fluctuation zone of the reservoir.

Contrast Behavior of Sandstone from Mount Nemrut (Adiyaman-Turkey) After the Accelerated Weathering Tests Topal, Tamer (2014-09-19) Mount Nemrut Tumulus is one of nine sites in Turkey inscribed into the UNESCO World Heritage List. Geological investigation was carried out in the field between 2006 and 2009 around Mount Nemrut and its close vicinity. There are statues and horoscopes made of sandstone. The Lower Miocene sandstone covers an area of approximately 0.46 km2. The sandstone seen at Mount Nemrut is gray, thin-to medium bedded, moderately weathered, weak to moderately strong. Bedding planes are detached both in the field and on th...
Assessment of rockfall hazard around Afyon Castle, Turkey Topal, Tamer; Ozden, Utku Ahmet (2007-09-01) The Afyon Castle is a tourist destination and a historical site in the City of Afyon in Turkey. The Castle is located on a steep hill, with a height of 226 m. In close proximity to the Castle there are settlements. The hill consists of trachitic andesite. The rock contains columnar joints and flow layering. Owing to these discontinuities, blocks of varying sizes had fallen down. The settlement areas near the Castle are now in danger because of the rockfall risk. In this study, rockfall analysis was carried ...
Assessment of environmental and engineering geological problems for the possible re-use of an abandoned rock-hewn settlement in Urgup (Cappadocia), Turkey Ulusay, Resat; Gokceoglu, Candan; Topal, Tamer; Sonmez, Harun; Tuncay, Ergun; Erguler, Zeynal Abiddin; Kasmer, Ozgu (2006-07-01) The Cappadocia Region of Central Anatolia having a very distinct culture is one of the attractive touristic sites of Turkey due to its spectacular and unique landforms and historical heritages. In this region, the structures carved into thick to massive tuffs survived and kept their original integrity for a number of centuries. Environmental and anthropological factors at the Cappadocia Region have been the main reasons for extensive subsurface and multi-purpose use in the past and present. In addition, the...
Investigation of Byzantine Mortars from a Basilica in Side Archaeological Site Güney, Bilge Alp (null; 2017-02-01) Side Archaeological Site is located in Antalya Province, Turkey. Although there are varying references about the foundation of the city, the city was most prosperous in the 2nd and 3rd century AD, during Roman period. The Byzantine Basilica in the city is dated back to 5th century AD. For the conservation works of the basilica, mortar samples were collected from different parts of the building and investigated for their basic physical, physico-mechanical and compositional properties. For the determination o...
Investigation on deterioration mechanisms on the basalts used in the Diyarbakır city walls Dursun, Felat; Topal, Tamer; Department of Geological Engineering (2017) The Diyarbakır City Walls (DCW), which were recently added to UNESCO’s World Heritage List, are among the largest and most impressive monuments from ancient times. Basalts having such different textural properties as massive and vesicular were employed as the principal material in the construction of the DCW. Like many other historical structures, the DCW are suffering from stone deterioration. A large variety of weathering forms can be observed on the basalts used in different sections of the DCW. This dis...
