In the north of Isparta, Senirkent and its surroundings, formations belonging to Barla Mountain, Senirkent and Kırdağ Anamas Units are located. In this study, samples were taken from limestones outcropping along the north and south of Senirkent town. Uluğbey Formation consists of thick-layered, occasionally oolitic and dolomitic limestones, Ergenli Formation consists of gray, medium-thick-layered algal limestones containing dolomitic levels. According to the fossils Orbitopsella sp., Lituosepta sp., Meandrovoluta asiagoensis, Everticyclammina sp., Siphovalvulina sp. detected in the formations, Liassic age was used for both formations, and it is represented by shallow, tidal flat and lagoon environment. Sulucandere and Beşparmak limestone formations are located in the south of Senirkent Town. Sulucandere Formation is composed of oolitic and oncoidal limestones intercalated with pelagic limestones. Characteristic fossils such as Gutnicella bizonorum, Gutnicella cayeuxi, Rectocyclammina sp, Callorbis minor, Andersenolina sp, Protopeneroplis striata, Spiraloconulus sp, Mesoendothyra sp. giving Dogger age were determined in the unit. According to this fossil assemblage, it can be said that it represents the continental slope, shelf environment between the platform and the open sea. Beşparmak Limestone Formation starts with limestones containing rudist clasts representing the shallow sea and shows a transition towards pelagic limestones representing the deep sea. It was determined that the formation characterizes the pelagic environment between the platform and the open sea, according to the fossils of Globotruncana arca, Rotundata calcarata, Abathomphalus mayaroensis and Globotruncana sp., which give a Cretaceous (Campanian-Maastrichtian) age.
