Sedimentological Aspects of Palu Formation (Pliocene-Quaternary), The East of Elazığ, Turkey

Abstract: The Palu Formation of Pliocene-Quaternary is found to the north of East Anatolian Fault Zone and Palu Anticline axis.Hacımekke and Avlağı villages in the north are surrounded by alluvial fan deposits and these deposits grade in thebraided river deposits to the south.Alluvial fan deposits consist of conglomerates and poorly sorted, pebbly sandstone with muddy matriks and show normal and reverse grading. Braided river deposits display two different depositional models. The Donjek type braided river deposists mainly consist of ibricated and organized conglomerates and through cross-bedded sandstones. These facies pass upwardsto te poorly sorted disorganized conglomearetes and sandstone layers of Scott type braided river deposits.Interrelations of the Donjek and Scott type facies show that tectonism was strong in the area during the PlioceneQuaternary period.
