Abstract: The Çaybağı formation (Upper Miocene-Pliocene?) which lies on E-W direction in the east of Elazığ, has beenfirstly recognized in this study. This formation mainly consist of conglomerate, sandstone, mudstone, coal interlayered claystone tuffite and limestone. It`s measuramble thickness is about 700 metres. To its sedimentary properties ten lithofacies havebeen recognized and grouped as lithofacies association. This lithofacies associations display of meandering river, braided riverand lake deposits.The braided river deposits consist of very coarse grained, poorly cemented,, trough cross-bedded sandstones whichbears red conglomerate lenses in some places. Meandering river deposits contain cannel fill, point bar and flood plain subassociations finning upward cycles. The lake deposits comprise marls with coal laminations and limestones including freshwater fossils (Unio indet).
