Article Citation - WoS: 3Citation - Scopus: 3Investigating the limestone quarries as geoheritage sites: Case of Mardin ancient quarry(De Gruyter, 2023) Karataş, Lale; Alptekin, Aydın; Yakar, Murat; Department of Architecture and Urban Planning / Mimarlık ve Şehir Planma BölümüAbstract: Abandoned quarries are valuable as a tourism element, as they exhibit the building material of the buildings built in the geographical area they are located in as historical objects. However, in order to determine how the quarries can be used for tourism purposes, it is necessary to determine the constraints on the choice of solution in spatial arrangements. The aim of this study is to investigate how the ancient limestone quarry of Mardin, which is a natural and cultural geological heritage, can be used for tourism and to develop suggestions. Within the scope of the study, in order to examine the possibilities of how an idle quarry located in Mardin province in Turkey can be used for tourism, the constraints in the selection of the post-use solution will be determined. In order to determine whether the Mardin quarry is accessible and safe to visit, various field studies were carried out in the study area, laboratory experiments and analyses. The caves were scanned with a 3D laser scanner, and its plans and sections were obtained. The findings were evaluated and suggestions were developed for the use of the ancient limestone quarry for tourism.Article Citation - WoS: 0Documentation of Material Deterioration on the Facades of Cultural Assets With the Use of Topographic Laser Scanning Method and Orthophotographs: Case of Mardin Mungan Mansion(Geomatik Journal, 2023) Karataş, Lale; Department of Architecture and Urban Planning / Mimarlık ve Şehir Planma BölümüIt is of great importance to determine and understand the factors and processes that affect the material deterioration in buildings, to apply appropriate protection interventions, to know in advance of the deterioration that will occur in the structures and to take precautions. Mardin Mungan Mansion, which is the subject of the study and is a historical stone structure reflecting the characteristics of traditional houses unique to the region. It is a structure formed under the determination of regional elements such as topography and materials. The aim of the study is to investigate the stone material problems of Mardin Mungan Mansion, which is a historical mansion reflecting the characteristics of traditional houses in the province of Mardin. In the investigation of material problems, observational detection and terrestrial laser scanning methods were used. As a result of the study, it is seen that by combining the data obtained from observational detection and orthophotos obtained from terrestrial laser scanning, a deterioration map can be created quickly and easily for the detection of material deterioration and restoration analysis. In the results obtained from the deterioration maps, on the facades of the Historical Mardin Mungan Mansion, surface pollution, blooming, faulty repairs due to the use of cement, and the problems of pouring the plaster made as a result of various faulty repairs were encountered. It is seen that the most important possible causes of damage to the structure are the negative effects of user-induced deterioration.Article Citation - Scopus: 2Deterioration Analysis of Historical Village House Structure in Mersin Kanlıdivane Archaeological Area by Uav Method(Mersin University, 2023) Karataş, Lale; Dal, M.; Department of Architecture and Urban Planning / Mimarlık ve Şehir Planma BölümüThe village house located in the Mersin Kanlıdivane archaeological site is one of the oldest settlements in the ruins, built in the second century. The house is mainly built of a yellowish beige limestone. This stone, which is the main material of the building, shows many deterioration patterns today. The aim of the study is to determine the dominant deterioration pattern of the stones in the village house structure in the Mersin Kanlıdivane archaeological site and to investigate the source of the deterioration. In order to investigate the deterioration patterns in the structure, the images obtained by UAV photogrammetry were interpreted and the types of deterioration were mapped. In the study, it is seen that even the types of material problems based on the smallest detail can be determined based on virtual visual inspection, thanks to UAV photogrammetry, without observing the structure in situ with UAV photogrammetry. The findings obtained in the study shows that the color change and surface loss deterioration on the stone surfaces has reached advanced levels as a result of the structure's exposure to the strong climate-induced sun and water effects for centuries. The results of the study show that the main damage observed on the stone surface of the structure is caused by the erosion by the effect of water. Restoration methods should be tried to stabilize the deterioration and replace the most degraded stones. It is recommended to use water-repellent surface coatings to protect the natural stone, especially against the intense water effect in the building. © 2023, Mersin University.

The traditional method for fixation relies on mechanical contact means and requires a great time effort to obtain a few preliminary points. In addition, the size of buildings and historical places make it difficult to examine the types of material deterioration, and on-site visual analyzes and current inspections by experts can also lead to human-induced errors. The development of methods based on UAV photogrammetry in order to reduce the labor force and margin of error in solving this situation brings great convenience for the detection of material deterioration in historical areas. The aim of the study carried out in this context is to document the material problems of "Sarışıh Han", a historical masonry building located in the Tarsus district of Mersin, which is of great importance for its continuity. Contributing to the documentation, detection and repair of financial problems for the preservation of the cultural heritage of the region and thus the sustainable management of the structures in the geographical region. In this context, material problems in the structure were documented using UAV photogrammetry method. In the study, the use of UAV photogrammetry to support the constraints of material deteriorations allows for more detailed results in façade analysis of material deteriorations, leading to simplification of manual and direct search procedures. © Author(s) 2022.Article Citation - WoS: 2Citation - Scopus: 2Material analysis for restoration application: a case study of the world’s first university Mor Yakup Church in Nusaybin, Mardin(SpringerLink, 2023) Karataş, Lale; Alptekin, Aydın; Yakar, Murat; Department of Architecture and Urban Planning / Mimarlık ve Şehir Planma BölümüThe Mor Yakup Church, located in the Nusaybin District of Mardin, is known as the world’s frst educational university in history and represents one of the oldest Christian medieval monuments. In this study, it is aimed to determine the factors of the strength problems of the structure by investigating the characterization of building materials and what kind of factors afect the material behavior with various observational and experimental methods. It was determined that the main deterioration types in the materials of the building were erosion, fractures, loss of parts and the dissolve of the joint mortars between the masonry work on the facades. Since the materials used in the construction of the building are unable in terms of physico-mechanics, it has been determined that the severe continental climate conditions prevailing in the region easily cause such physical deterioration on the construction materials. In addition, the presence of clays in the conventional mortar used in the building has been defned as an internal problem that causes the material to get tired with the osmotic pressure it creates by absorbing water. A very high rate of salinization was detected in the building materials of the building and it was observed that this salting was caused by the acid efect caused by air pollution and the portland cement used in the previous repairs in the building. Finally, this study presents restoration recommendations to repair the material deterioration in the building and to prevent its occurrence in the future.Article Citation - Scopus: 2Investigating the Historical Building Materials With Spectroscopic and Geophysical Methods: a Case Study of Mardin Castle(Murat Yakar, 2023) Karataş, Lale; Department of Architecture and Urban Planning / Mimarlık ve Şehir Planma BölümüToday, the building materials form the historical buildings are being exposed to various deteriorations increasingly due to different causes. Many historical masonry constructions in the world are on the edge of extinction due to the increasing frequency and changing models of material deterioration. The materials as close as possible to the original materials in terms of their chemical compositions and physical properties are required in the reconstruction and maintenance of the buildings that have historical importance. In addition, the properties of the materials used in the historical buildings are generally not known with a sufficient accuracy. This causes misapplications in case of emergencies, and also may lead to future potential greater damages on the building. The lack of data regarding the engineering properties of these buildings causes long-term damages on the buildings due to inappropriate conservation methods and materials. Therefore, it is necessary to investigate the properties of certain materials for application in the renewal of the historical buildings. Within this context, in this study the construction materials of Mardin Castle, which is located in Mardin Province, Turkey and existing for centuries as the symbol of the city, are investigated and its properties are reached. Experimental research methods were used in the study. Primarily, the castle structure was examined on-site by field study and sampling was carried out from the areas determined. The samples were analyzed via various spectroscopic and geophysical methods, and various findings were achieved. Relatively variable and high levels of salinization were determined in the findings regarding the average values in stone samples of Mardin Castle’s Fortification Walls. Results of the research document the conservation status regarding Mardin Castle and provide an experimental base and also a theoretical support for the conservation of historical buildings in Turkey; and present indicative suggestions to establish conservation schemes of the historical buildings. © Author(s) 2023.Article Taş Yapıların Cephelerindeki Malzeme Bozulmalarının Yersel Lazer Tarama Yöntemiyle Araştırılması: Mardin Konağı Örneği(2023) Karataş, Lale; Alptekin, Aydın; Yakar, Murat; Department of Architecture and Urban Planning / Mimarlık ve Şehir Planma BölümüYapılarda meydana gelen malzeme bozulmalarına etki eden faktörlerin ve süreçlerin doğru bir şekilde belirlenmesi ve anlaşılması, uygun koruma müdahalelerinin uygulanması ve yapılarda meydana gelecek bozulmaların önceden bilinmesi ve önlem alınması açısından büyük önem taşımaktadır. Çalışmaya konu olan ve yöreye özgü geleneksel konutların özelliklerini yansıtan tarihi taş bir yapı olan Mardin Konağı, topografya, malzeme gibi bölgesel unsurların belirleyiciliği altında oluşmuş bir oluşumdur. Çalışmanın amacı Mardin ilinde geleneksel konutların özelliklerini yansıtan tarihi bir konağın taş malzeme sorunlarının araştırılmasıdır. Malzeme sorunlarının araştırılmasında gözlemsel tespit ve yersel lazer tarama yöntemleri kullanılmıştır. Çalışma sonucunda yapıda en sık görülen malzeme bozulma türlerinin yüzey kirliliği ve bitki oluşumu olduğu görülmüştür. Cephelerdeki yoğun düzeyde kararmaların artan hava kirliliğinin etkisiyle meydana geldiğini düşünülmekte olup, yöredeki yapılarda hava kirliliğini cephelerde meydana getirdiği zararlara yönelik önlemlerin alınması gerektiğini önerilmektedir.
