Abstract: The principal mountains of the region studied, are Artos (3475m), Pelli (3060 m), Singer (2900 m), Arnas (3550 m) ,and Kuvveşehap (3500 m).The stratigraphy of the southeastern region of Lake Van is somewhat complicated.The stratigraphic column consist of the following: Paleozoic (Upper Permian), Upper Cretaceous (Maestrichtian), Upper Cretaceous-Paleocene, Eocene,Neogene, ,and Quaternary.Quartzites, Limestones, Crystalline Limestones ,and Schists make up the Upper Permian in the area. Schwagerina, Parafusulina, Polydiexodina were identifiedin the limestone member.The Conglomerates, foliated limestones, Globigerina limestones ,and radiolarites form the Upper Cretaceous.In the last two fossiliferous units, Globigerina cf. cretacea, Globotruncanalinnei d`Orb. Globotruncana cf. stuarti J. de. Lapp. Cyclolites krumbecki Stef.,Trochosmilia bilobata Mich.; Hippurites loftusi Wood, Exogyra columba Lamk.,Loftusia elongata, Lagena diffringens J. de Lapp. were identified.A mixed facies of limestones, marls ,and sandstones, overlay the Upper Cretaceous. Due to fossil content this facies is placed in the Upper Cretaeeous ,and Paleocene; Miliolidae, Nummulites sp. Miseellanea miscella cf. d`Arch, Lithophyllum,Globigerina cf. cretacea, Globotruncana cf. stuarti J. de Lapp. were identified inthe limestone units.
