In the Lutetian aged unit with shelf sediment character, greenish gray colored Nummulites sp. and Assilina sp. carbonate sandy shales containing carbonate, greyish blue colored abundantly fossiliferous sandy limestones, very durable, grayish beige abundantly fossiliferous limestones reaching a thickness of 50 cm in places, sandy, abundantly fossiliferous durable limestones containing live digging traces and moulds, ash colored carbonated, sandy, highly dispersed and Relatively sparse fossiliferous clay levels were identified by us. Towards the upper levels of the unit, greyish-beige colored, very durable, abundant Nummulites sp., reflecting its general character. and Assilina İstanbul’un Jeolojisi Sempozyumu 6 98 sp. It is observed as limestone containing The level, which is up to 3 meters thick in places, in a quarry opened to obtain materials in the northeast of Hatipler District, consists entirely of Nummulites and Assilina fossils. This level is an important geological heritage and must be protected. In this paper, the geological heritage potential of the Hatipler Formation and how it should be protected will be discussed.
