Microfacies Features of the Kahtepe Limestone North of Hadim (konya, Türkiye)

Abstract

The aim of this study is to define the microfacies properties of Upper Permian Kahtepe Formation limestones. The Kahtepe Formation begins with dark gray, abundantly fossiliferous, micritic limestone; it continues upwards with medium-thick bedded limestones with fusulinids, pellets, intraclasts, calcite veins, and stylolites. The Kahtepe Formation continues with thin-medium bedded limestone with oolitic packstone-grainstone characteristics. The unit contains an intermediate level consisting of yellow-pink colored, thin-medium bedded shale-quartzite intercalation at the top. On the intermediate level, fusulinid, Ammodiscus, Glomospira, micrite-microsparry, gray colored, thin-medium bedded, coral limestone is overlain and gray colored with gastropod, Mizzia, fusulinid, oncoid, crinoid, quartz fragments, mitrite-microspar continues with thin-medium bedded limestone. Above, it is in the form of gray-colored, thin-medium bedded limestone with bioclast and quartz fragments, intraclast, pellet, Ammodiscus, ostracod, micrite-micro spar, and sparry cement. At the top, the formation is gray-colored, thin-medium bedded limestone containing Mizzia, Ammodiscus, Glomospira, ostracod, quartz, pellet, intraclast, and micrite. At some levels of the Kahtepe Formation, <5% dolomite mineral was also encountered. The mudstone, wackestone, packstone, and grainstone microfacies of the Kahtepe Formation limestones were developed in Wilson’s (1975) seven (Shelf lagoon: open circulation) and eith (Shelf and tidal plains: limited circulation) carbonate belt environments.
