    Geological and petrographical features of the Çatmakaya (Seydişehir-Konya) bauxite deposit [Çatmakaya (Seydişehir-Konya) boksit yata?inin jeolojik ve petrografik özellikleri]
    (2003) Karada? M.M.; Temur S.; Arik F.; Öztürk A.
    The upper Cretaceous Katrangedi?i formation comprising carbonaceous rock occurs at the base of the bauxite in the study area, which is located 30 km to the south of Seydişehir and 500 m to the west of the Çatmakaya village. The Upper Cretaceous (Senonian - Maestrichtian) Do?ankuzu formation lies on the bauxite deposited in the karstic openings at the upper part of the Katrangedi?i formatoin. These units are overlain discomformably by the Paleocene Yarpuz formation, the Eoecene A?açtepesi formation, and rocks of the Bozkir Unit (Bozkir melange) replaced to the sudy area by napping. The Çatmakaya bauxite deposit has a lens shape with 50 to 200 m in dimension aligned to NE-SW. The deepest part of the paleo-sinkhole, in which ore was deposited is 10 m and tha average tickness of ore deposit is about 3 m. The Çatmakaya bauxite is boehmitic. Besides boehmite, the one involves little amount of kaolinite, diaspore, hematite, goethite, limonite, pyrite, marcasite, anatase, rutile, quartz, tridymite and calcite in the ore deposit. According to this mineralogical composition, the Çatmakaya bauxite ore does not show important differences from other ore deposits around Seydişehir. Five types of mineralization were identified in the studied ore deposits. These are massive, oolitic - pysolithic, clayey, iron -bearing and brecciated bauxites. Oolitic - pysolitic mineralization occurs everywhere in the ore deposit. Brecciated mineralization are commonly observed near the limestones above and below the ore deposit, while iron-bearing and clayey bauxited intensified at the lower part of the ore deposits. The common presence of boehmite in the ore deposit indicates that the temperature of the environment was over 155°C. The presence of pyrite points the hematite suggests that Eh of the environment was below -0.3 and goethite and psilomelan points that the pH of the environment was higher than 7, respectively.

    Geological, petrographical and technological investigations of Erkilet Basalt, Kayseri, Central Anatolia [Erkilet bazalti'nin jeolojik, petrografik ve teknolojik incelemesi, Kayseri, Orta Anadolu]
    (2007) Temur S.; Temur Y.; Kansun G.
    The study is executed in a wide area ofthe around Kayseri. Basalts are prevalent in northwest and southeast of this area, and are produced in the surroundings of Erkilet. The aim of this study is the determination of production as building stone, depending on its geological setting, mineralogical and petrological properties, geochemistly, and technological testes of the basalt. Erkilet Basalt is the unit which belong to Miocene-Quaternary aged volcanites in the area. Mineralogically Erkilet Basalt contains 40-42% microlites of plagioclase, 20-25% clinopyroxene, 18-20% olivine, 4-5% phenocrystales of plagioclase, 3-5% orthopyroxene, calcite less than 4%, opague mineral less than 4%, and these basalts which indicatg: holocrystalline and porphyritic textures have composition of pyroxene-basalt. Geochemically, these rocks conform thoelitic-alkali composition according to distribution of K2O-SiO2, basalt according to distribution of (KO2 + Na2O) -SiO2, sub-alkali basalt according to distribution of Zr/TiO2-Nb/Y, intracontinental basalt according to distribution of (Zr/Y)-Zr, and composition of continental basalt of late-post orogenic belt indicating effects of continental crust. Density, unit weight, rate of water suction in point of weight, pressure resistance, pressure resistance after than frost, frost loss and pressure resistance of this rock appropriate for using being both natural building stone and coating stone. Plate giving, cutting of edge-corner, and varnish taking of this rock is at good degree. Average abrasion resistance of that is very near to the limit value.
