Black Sea coast line is a hazardous region especially in winter due to the dominant wave action. Therefore, rubble mound breakwaters used as ship shelters are vital structures especially for the fishermen. Construction of the breakwater requires good quality durable armourstones. Due to the nature of the rubble mound breakwaters, armourstones having various sizes and types are used in the construction of these structures. The deterioration of these armourstones with time in the form of abrasion and disintegration may result in the failure of the breakwater. Therefore, it is important to investigate the durability and quality of the armourstones to be used in these structures. In this thesis, the properties of the armourstones taken from five rock quarries and used in the Hisarönü (Bartın), the Tarlaağzı (Bartın) and the Alaplı (Zonguldak) rubble mound breakwaters were studied both in field and laboratory in order to assess their qualities and long term durabilities. Based on the in-situ observations and laboratory tests, the Kavakdere, Kavukkavlağı and the Tarlaağzı limestones are good (durable) rocks. However, the Çömlekçikuyu andesite is found to be generally marginal rock, and the Kıran sandstone is poor rock. CIRIA/CUR, RDId, RERS and Wet-Dry strength ratio classifications are in good agreement with the in-situ observations and the results of the laboratory tests. However RDIs, Average Pore Diameter and Saturation Coefficient classifications do not fully reflect the reality.

Evaluation of andesite source as armourstone for a rubble mound breakwater (Hisaronu, Turkey) Ozden, Utku Ahmet; Topal, Tamer (Springer Science and Business Media LLC, 2009-11-01) Black Sea coast line is a hazardous region especially in winter due to the dominant wave action. Therefore, rubble mound breakwaters protected with armourstone used as ship shelters are vital structures especially for the fishermen. The deterioration of the armourstone with time in the form of abrasion and disintegration may result in the failure of the breakwater. In this study, the properties of the armourstone taken from an andesite quarry and used in the Hisaronu rubble mound breakwater were studied bot...
Assessment of durability criteria of the armourstones used in Mersin and Kumkuyu harbors based on their site and laboratory performances Ertaş, Burcu; Topal, Tamer; Department of Geological Engineering (2006) Breakwaters are constructed in coastal areas to protect coastal engineering structures from wave actions. Due to economic reasons, natural stones (armourstone) are very frequently used for the constructions of the breakwaters. Considering the functions of the stones at different zones of the breakwaters, various sizes with variable properties of the armourstones are used in breakwaters.Deterioration of armourstones with time in the form of abrasion and disintegration may end up with the damage of the engine...
Quality Assessment of the Armourstones for Some Black Sea Rubble Mound Breakwaters, Turkey Ozden, U. A.; Topal, Tamer (2007-01-01) The Black Sea coastline is a hazardous region in Turkey, especially in winter, due to the dominant wave action. Therefore, rubble mound breakwaters used as ship shelters are vital structures, especially for the fishermen. Construction of the breakwater requires good quality, durable armourstones. Due to the nature of the rubble mound breakwaters, armourstones of various sizes and types are used in the construction of these structures. The deterioration of these armourstones with time may result in the failu...
Mafic microgranular enclaves and interaction between felsic and mafic magmas in the agacoren intrusive suite: Evidence from petrographic features and mineral chemistry Kadioglu, Yusuf Kagan; Güleç, Nilgün Türkan (Informa UK Limited, 1996-01-01) The Agacoren Intrusive Suite is exposed as a large intrusive body over ∼500 km2 east of Lake Tuz in central Anatolia and consists of the Cokumkaya gabbro, the Agacoren granitoid, and young dikes. The Agacoren granitoid is the predominant lithology of the Agacoren Intrusive Suite, and is differentiated into several subunits ranging in composition from monzonite, through granite, to alkali feldspar granite. The Cokumkaya gabbro occurs as stocks enclosed in the Agacoren granitoid; individual bodies range in si...
Erosional truncation of uppermost Permian shallow-marine carbonates and implications for Permian-Triassic boundary events Payne, Jonathan L.; Lehrmann, Daniel J.; Follett, David; Seibel, Margaret; Kump, Lee R.; Riccardi, Anthony; Altıner, Demir; Sano, Hiroyoshi; Wei, Jiayong (Geological Society of America, 2007-07-01) On shallow-marine carbonate buildups in south China, Turkey, and Japan, uppermost Permian skeletal limestones are truncated by an erosional surface that exhibits as much as 10 cm of topography, including overhanging relief. Sedimentary facies, microfabrics, carbon isotopes, and cements together suggest that erosion occurred in a submarine setting. Moreover, biostratigraphic data from south China demonstrate that the surface postdates the uppermost Permian sequence boundary at the global stratotype section a...
