The Karakartal mining exploration field is located in Eastern Anotalia, close to Erzincan-Kemaliye. The field is an important metallic mining exploration area with high potential of Copper and Gold production. In this study, characterization of the mineral deposition are analyzed using geostatistical techniques. Subaşı Volcanics, Keban Metamorphics and Munzur Limestone are the basic geologic units in the mining area. The variations of chemical parameters with depth were examined. Descriptive statistics, areal distribution, linear regression analysis, trend surface analysis, principal component analysis were used to characterize ore body at the study area. Minimum, mean and maximum values and variances were determined by using descriptive statistics methods. Areal distribution models show intense values for copper mean, copper maximum, manganese maximum, zinc maximum and zinc mean values at the western part, other models show accumulation groups at the eastern site. Linear regression table shows high relations between gold-copper and, zinc-cadmium and lead, and potassium-sodium-barium- beryllium-calcium and aluminum. Trend surface analysis maps show northeast – southwest trend for copper, manganese and zinc, and southwest – northeast trend for gold. As a result of principal component analysis there are eight representative component groups for all elements. As a result of this study the regional distribution of the elements in the mineral deposition zone and their relationships with each other was determined by using results of the laboratory analyses of the drilling wells and geostatistical techniques together.

Assessment of slope stability and monitoring of a landslide in the Koyulhisar settlement area (Sivas, Turkey) Topal, Tamer (2015-09-01) The Koyulhisar settlement area is located in the seismically active zone of Kelkit valley. The settlement area has been adversely affected by active landslides as a result of which some of the houses have been evacuated. In this study, areas within the Koyulhisar settlement area where the landslides exist were delineated with a field mapping technique, and active landslides were investigated by means of field observations, drilling, sampling, field and laboratory testing, and in situ monitoring using an inc...
Modeling of mogan and eymir lakes aquifer system Yağbasan, Özlem; Yazıcıgil, Hasan; Department of Geological Engineering (2007) Mogan and Eymir Lakes, located 20 km south of Ankara, are important aesthetic, recreational, and ecological resources. Dikilitaş and İkizce reservoirs, constructed on upstream surface waters, are two man-made structures in the basin encompassing an area of 985 km2. The purpose of this study is (1) to quantify groundwater components in lakes’ budgets, (2) to assess the potential impacts of upstream reservoirs on lake levels, and (3) to determine effects of potential climatic change on lakes and groundwater l...
Characterization of the Karababa-C reservoir in the South Karakus oilfield, southeast Turkey Ulu, M; Karahanoğlu, Nurkan (1998-12-01) The South Karakus oil field is located in southeast Turkey, and produces, from the Late Cretaceous Mardin Group, carbonate reservoirs consisting of the Karababa, Derdere, Sabunsuyu and Areban Formations. The Karababa Formation is divided into three members, of which the productive Karababa-C member, discussed here, is composed of shallow marine bioclastic mudstone to wackestone. It is affected by early to late diagenetic processes that caused modification of the original pore system by cementation, dissolut...
GEOLOGICAL HISTORY OF THE NORTHWARD ARCHED SEGMENT OF THE NORTH ANATOLIAN TRANSFORM-FAULT ZONE DIRIK, K (Wiley; 1993-12-01) The study area is located in the southern part of the Central Pontides. The rocks exposed in this region have been divided into three major groups: basement, cover sequence and volcanic rocks. The basement rocks are composed of metamorphic units and a chaotic assemblage derived from an accretionary prism produced during the northward subduction of northern Neo-Tethys during the Late Cretaceous. During the same period, the basal element of the cover sequence, a thick and coarsening upward flysch succession (...
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...
