Abstract: There are two different types of basements in investigated area. To the east of Daday-İnebolu line, basement is composed of phyllites, slates and metaophiolites which are Triassic to Lower Jurassicin age. These are Paleotethyan deposits which were crossed by intrusions and extrusions in the earlyDogger age. Precambrian and Paleozoic units crop out around Karadere stream to the west part ofDaday-inebolu line. In the Karadere Stream, rocks of Upper Cambrian and Lower Ordovician overliethe units of Precambrian age with primary stratig raphic contact. Paleozoic units form Cambrian toCarboniferous show two regressive sequences. Per mo-triassic sediments which was deposited in a continental environment overlie older sediments with an angular unconformity. The collision betweenGondwana and Laurasia continents caused overth rusting. So, Paleozoic assemblages that belong toGondwana cantinent overthrusted the Paleotethys deposits such as slightly metamorphosed flysch faciesand metaophiolites, form S-SW to N-NE in Dogger. Tectonic features which are caused by this collisioncan be distinguished in the investigated area. Sediments which are younger than Upper Liassic, covered all these tectonic features and older units, tra nsgressively. Transgression progresses continuouslyuntil Upper Paleocene. Island arc volcanic activity which belongs to north dipping Neotethyan subduction zone beneath the Pontides, started in pre-Aibian times. Eocene sediments which were deposited onthe older units with an angular unconformity show different facies in the investigated area. Variousterrestrial deposits are developed during Neogene. These are followed by young alluvium.
