ABSTRACT: The studies area covering near Kelkit (Gümüşhane) region, is located in. Fontid tectonic unit and in its south zone. In this study beeing based on litfaosteatigraphy laws, seven units have been identified in the formation rank. Gümüşhane granite forms the basement of study .area.., Lias aged. Zimonköy formation forming the first marine rocks consist of sedimantary-volcanic character .and represents lateral, .and horizontal fades changes, Berdiga formation, all of which is developped in carbonaceous faciès» composed of mainly sandy limestone, dolomitic limestone and dolomites. Upper cretaceous aged. Kermuidere formation is représentée by conglomerates, derived mainly Berdiga formation. Paleocene aged Ziyarettepe formation is framed-by red sandy limestone developped in. open marine environment.., Alibaba formation is developped in three different faciès that are laterally interfingerig at Middle Eocene- Lower Miocene time,.. Smırgöltt limestone: which is recognized by horizontal limestone is deposited in restricted environment
