Stratigraphic Features of the Yesilyurt-Konak Area (Malatya, Turkey)

The stratigraphic sequence in the study area starts with the Carboniferous-Triassic Malatya Metamorphics, which are composed of marble and schist and covered unconformably by the Maastrichtian Gunduzbey Group. The group includes the Kizilguney Formation with conglomerate and sandstones, and the Kapullu Formation containing limestone-marl alternations, with turbiditic sandstone intercalations. The sequence continues with the Lutetian Yesilyurt Group, which includes the Zorbon, Yukaribanazi, and Gedik Formations, unconformably overlying the Kapullu Formation. The Zorbon Formation is composed of conglomerate interbedded with sandstone and mudstone, whereas the Yukaribanazi Formation consists of sandstone and shale alternations with intercalations of conglomerates and olistoliths. The Gedik Formation is composed of reefal limestone, claystone, and marl, and underlies the Pliocene-Quaternary Beylerderesi Formation formed of conglomerate interbedded with sandstone. Holocene alluvium unconformably overlies all units in the region.
