Contrast Behavior of Sandstone from Mount Nemrut (Adiyaman-Turkey) After the Accelerated Weathering Tests

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 the statues. This study investigates the weathering of the sandstone at Mount Nemrut from both field and laboratory observations. The laboratory tests revealed that wetting-drying, freeze-thaw and salt crystallization reduce the strength of the sandstone. In the case of the sandstone, wetting-drying and freezing-thawing give rise to splitting along bedding planes. The wind causes rounding of the sharp corners of the stela. It is seen that two type’s sandstones are outcropped. In the field it is difficult to distinguish sandstone types but in the laboratory it is easily detected from their weathering degrees and colors. Dark gray sandstone is found to be more resistant to the ageing tests than the light gray sandstone.


Seismic evaluation and strengthening of nemrut monuments
Aktas, Yasemin Didem; Türer, Ahmet (2015-05-01)
Nemrut Dag Tumulus and Monuments, constructed during the Commagenian Kingdom approximately 2000 years ago on the peak of Mount Nemrut, is a UNESCO World Heritage Site in Turkey. The region is about 5 km away from the East Anatolian Fault, therefore, this paper focuses on dynamic testing and earthquake simulations carried out within the framework of the Commagene Nemrut Conservation Development Program in order to explain monuments' current condition. The simulations showed vulnerability of cut-stone blocks ...
Assessment of deterioration and collapse mechanisms of dolomitic limestone at Hasankeyf Antique City before and after reservoir impounding (Turkey)
Topal, Tamer (2016-01-01)
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 th...

The focus of this study is on the Nemrut Dag monuments, which were constructed approximately 2000 years ago at the peak of Mount Nemrut, 2206 meters elevation, are among the most valuable historical heritage sites in Turkey. Since the discovery of Nemrut monuments in 1881, many questions are unresolved, such as how the monuments were destroyed and why the damage level is very different between the symmetric east and west terraces. Natural causes, such as earthquakes, snow, or wind or manmade damages in the ...
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 ...
Durability assessment of the basalts used in the Diyarbakr City Walls, Turkey
Dursun, Felat; Topal, Tamer (Springer Science and Business Media LLC, 2019-08-01)
The Diyarbakr City Walls (DCW), which were recently added to UNESCO's World Heritage List, are among the largest and one of the most impressive monuments from ancient times. The history of the DCW stretches back more than 4000 years, therefore making the extant City Walls a combination and reflection of influences of the various civilizations that settled in the region. Basalts having such different textural properties as massive and vesicular were employed as the principal material in the construction of t...
