The aim of this study is to investigate in detail the basic stratigraphy of the north of Lake Hoyran which is situated in the northern part of the Western Taurus. The lithostratigraphic units have been differentiated into two groups, as autochthonous and allochthonous units, according to their lithologic and structural characteristics. Autochthonous units begin with the Sultandede formation of the Upper Cambrian-Lower Ordovician age. This formation is unconformably overlain by a continuous sedimentary sequence which is of Liassic to Middle Eocene age. The Mesozoic transgression begins with a thin basal conglomerate and continues up to the Middle Eocene. Marine carbonates were deposited before the Maestrichtian, whereas shallow marine carbonates and pelagic sediments were formed between the Maestrichtian and Middle Eocene. However, flysch facies were dominated in the Middle Eocene as the sedimentary environment became deeper. The allochthonous Hoyran ophiolite was emplaced by a tectonic contact after the Middle Eocene. During the Upper Miocene and Pliocene, terrestrial sediments were deposited in both channels and lakes which unconformably overly the older rock units. The study area was uplifted at the end of the Pliocene.
