dc.description.abstractThe objective of this study is to determine the sedimentary properties of dolomites (Upper Jurassic) in terms of petrography, which belong to the Hacialabaz Formation existing at the surroundings of Bagbasi District lying at the south of Konya City. Dolomite, the unit formed with dolomitic limestone and limestone begins with gray or dark gray colored, moderate-thick layered, sugar textured dolomitic limestones including micritic intermediate layers at the bottom, and continues with gray colored, medium layered limestones through the upper parts. Dark gray colored, moderate-thick layered breccioid like appearing limestone at some layers and dolomitized intermediate layers form the upper parts. Hacialabaz Formation has begun to settle as the direct carbonate sedimentation in a transgression making sea after a long emerging period. Green algae like Clypeina jurassica, Cambelliella striata, Salpingoporella sp. and foraminifera fossils like Valvulina lugeoni, Kurnubia cf. palastiniensis, Valvulamina sp., Opthalmidium sp., Siphovalvulina sp., Haurania sp., Miliolidae were found in the Hacialabaz Formation settled in shallow-marine carbonate platform environment (tidal-subtidal and restricted lagoon). Eight dolomite-rock textures are recognized and classified according to crystal-size distribution and crystal-boundary shape. These is made of unimodal, very fine to fine-crystalline planar-s (subhedral) mosaic dolomite; unimodal, medium to coarse-crystalline planar-s (subhedral) mosaic dolomite; coarse to very coarse- crystalline planar-s (subhedral) dolomite; medium to coarse-crystalline planar-e (euhedral) mosaic dolomite; medium to coarse-crystalline planar-e (euhedral) dolomite; coarse to very coarse-crystalline non-planar-a (anhedral) dolomite; coarse to very coarse-crystalline non-planar-c (cement) dolomite; polymodal, planar-s (subhedral) to planar-e (euhedral) mosaic dolomite. Dolomitization is closely associated with the development of secondary porosity; dolomitization pre-and post-dates dissolution and corrosion and no secondary porosity generation is present in the associated limestones. The most common porosity types are non-fabric selective moldic and vuggy porosity and intercrystalline porosity. These porous zones are characterized by late-diagenetic coarse-crystalline dolomite, whereas the non-porous intervals are composed of dense mosaics of early-diagenetic dolomites. The distribution of dolomite rock textures indicates that porous zones were preserved as limestone until late in the diagenetic history, and were then subjected to late-stage dolomitization in a medium burial environment, resulting in coarse-crystalline porous dolomites. Hacialabaz dolomites have been formed as early diagenetic at the tidal-subtidal environment and as the late diagenetic at the shallow-deep burial depths.en_US
