In 2017, a field survey program was started in Soran province, focused on the identification of new archaeological sites and in order to obtain new data and greater precision on archaic settlements in the three main areas that make up this region (Dyiana , Haji Omaran, Harir). This research, also in progress, has made it possible to infer aspects such as the scientific knowledge of each one of them, providing updated data on their location, relative chronology and, above all, an update on their affectation and state of conservation.
24 points of archaeological interest have been visited and surveyed, some of them unknown and others mentioned in the archaeological chart of Iraq (Baghdad 1976). It has been possible to identify Ubaid ceramic fragments (Zar Gali) and other hand-made productions that present prehistoric chronology (Bapeshatain, GIRD a Mir). The presence of ceramics has been a constant in all the deposits, although its ascription is complex since some of them present large chronological sequences (Qalat Sur, Khazna, Qalat Sede, Mawatan and Sur Sura 2). The main occupation belongs to the final Chalcolithic LC 4-5 (TLE or Harir) to the Iron Age (documented in all areas), considering the Islamic period as a separate phase further from our objectives. It is relevant to highlight the finding in several of these settlements of important architectural remains related to large and small settlements with different occupational phases.
In this case, in relation to well-located deposits on the border between Iran and Iraq, generating new data on trade and raw material resources shared by human communities over time and the difficulties in their management and transfer. It appears that these communities developed different responses in the three areas where the surveys were conducted, such as Diyana, Harir and Haji Omaran. These evidences, whether long or intermittent sequences, seem to indicate a stable use of the area since the Paleolithic with less affected stratigraphies than in other points of upper Mesopotamia.
