Öğe Petrographic and geochemical characteristics of dolomites of Ki{dotless}zi{dotless}loren formation (Konya, Turkey)(2008) Dinc S.; Orhan H.The Upper Triassic-Lower Jurassic Ki{dotless}zi{dotless}loren formation outcroping around the Ki{dotless}zi{dotless}loren mountain, 40 km to the west of Konya begin with dolomite at the base and, grades upward into calcitic dolomite, dolomitic limestone and limeston,. Dolomites are two types; mimetic and non-mimetic. In mimetic dolomit, pellet fossils, ooid and intraclast were poartially or totaly preserved. In non-mimetic dolomite, the depositional texture were totaly destroyed. It is composed of euhedral, hemihedral, dirty-brownish coloured, non zoned and fine to coarse dolomite crystals with linear and intended crsytal boundaries. The CaCO3, MgCO3 ratios and Sr, Mn, Fe content of dolomites are determined as % 53-61mol, % 39-47 mol and 65-171 ppm, 3-37 ppm, % 0,01-0,12 respectively. Having a MgCO3 ratio close to % 50 and a low Sr content are interpreted as the dolomite in the study area was approached to the stoichiometric dolomite. The Sr+2/Ca+2 ratio of dolomitization solution was calculated as having a range between 0,023-0,066. This is higher than present day sea water, and can be interpreted as either the Sr+2/Ca+2 ratio of oceanwater when Ki{dotless}zi{dotless}loren formation formed was higher than today seawater or unsufficient removal of Sr in diagenetic environment during transformation processes of aragonitic limestone to dolomite.Öğe Sedimentological chacteristics of the Aydincik Tufa (Mersin, Turkey)(2011) Orhan H.; Köse F.[Abstract not Available]
