7185-6515 BCE. Below it is Phase IV, which is dated to 7595-7145 BCE, in the terminal Pottery Neolithic. Phase V is dated to 7940-7610 BCE, in the late Pottery Neolithic. Phase VI, the bottom layer, has not been radiocarbon dated but is estimated to belong to the middle Pre-Pottery Neolithic. Another site, known as Akarçaytepe 2, is located 250 m northeast of Akarçay Tepe, on both sides of the Su Dere. This is 300 m north of Akarçay village. It was first identified by G. Algaze's team in 1989, who identified finds from the Ubaid and Uruk periods of the Chalcolithic, along with the Middle Bronze Age. Akarçay Höyük Akarçay Höyük is a medium-sized mound, measuring 180x160 m, located 900 m south of Akarçay village. In Algaze's team's 1989 survey, pottery shards from the Early and Middle Bronze Age, Hellenistic period, Roman period, and Byzantine period were found here. Salvage excavations were conducted in 1998 under Y. Mergen and A. Deveci, and these excavations uncovered Early Bronze Age "metallic ceramics" samples, similar to ones found at Hayaz and Samsat. Then in 2001 a team led by M. Özdoğan and N. Karul uncovered Late Neolithic, Late Chalcolithic, and Byzantine-era artifacts. There is also a 13th-14th century CE cemetery at the site. Other sites Gre Virike: a small mound, measuring 60x70 m in diameter and 15 m in height, located near the village. First identified in 1989 by G. Algaze and then surveyed in 1998 by A.T. Ökse, who found artifacts dated to the Late Chalcolithic and Early Bronze Age. Ökse then did a salvage excavation here in 1999 and concluded that the settlement at Gre Virike served as a cult center for surrounding villages during the Early Bronze Age. Özdoğan and Karul also did surface examinations here in 2001 and found various Early through Late Chalcolithic as well as Early and Middle Bronze Age. Gre Virike Yanı: first identified by G. Algaze in 1989; Özdoğan and Karul did a surface inspection in 2001 and they found items dated from the Iron Age. Karakız Höyük: surface examinations by Özdoğan and Karul at this small mound produced finds dated to the Ubaid phase of the Chalcolithic, Early and Middle Bronze Age, Iron Age, and Roman and Byzantine periods. Gre Gavuran: surface examinations by Özdoğan and Karul at this small mound produced finds dated to the Late Neolithic, Late Chalcolithic, Early and Middle Bronze
