Abstract

The Upper Triassic-Lower Jurassic KД±zД±loren formation outcroping around the KД±zД±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 KД±zД±loren formation formed was higher than today seawater or unsufficient removal of Sr in diagenetic environment during transformation processes of aragonitic limestone to dolomite.
