Paleontologic and Stratigraphic Features of Upper Cretaceous Units in the Vicinity of Hekimhan (Malatya)

Abstract: The purpose of this research is the investigation of the paleontology and stratigraphy of studied area,located to the south of Hekimhan (Malatya, 1/25 000, feste).The oldest unit in this area is Ophiolites which is emplaced pre-Upper Cretaceous. Campanian-Maestrichtianaged flysch sediments overlies this Ophiolite unconformably. Yığma member, locating at the bottom of the Hekimhanformation codnsisting of conglomerate, sandstone, claystone and mudstone in 110 m. thickness. This unit overlivedconformably by sediments called as Çöreklik member in flysch facies. Reefal limestones area named as Kuşkayamember in 28 m. are located at the top this cequence.After investigation several samples taken from four stratigraphic sections which are measured from the flyschsediments, planktonic foraminifer zones have been classified as follows; Globotruncanita elevata (Campanian).Globotruncana area (Lower Mazstxichtian) and Rosita contusa (Middle Maestrichtian).
