خلاصة:

Archaeological excavations on the western part of the Central Iranian Plateau, known as the Qazvin Plain provides invaluable information about the sedentary communities from early occupation to the later prehistoric era. Despite the past archeological data, chronological studies mostly rely on the relative use of the Bayesian modeling for stratigraphically-related radiocarbon dates. The current paper provides a new model for excavations and the chronological framework based on new radiocarbon dating of the six key archeological enclosures in the Qazvin plain. A Bayesian analysis of these data is presented on a site-by-site basis to give the best chronologies. Finally, all dates are combined into a single model of the chronology of the Qazvin Plain from the Late Neolithic to the Iron Age. The procedure aims to use the Bayesian model to predict the transition points between the archaeologically-defined periods with the highest possible precision, to redefine the existing chronology for the Qazvin Plain.

Mark Pollard1, Hossein Davoudi2, Iman Mostafapour3, Hamid Reza Valipour4, Hassan Fazeli Nashli5 Received: 2011/10/25 Accepted: 2011/12/26 Abstract Archaeological excavations on the western part of the Central Iranian Plateau, known as the Qazvin Plain provides invaluable information about the sedentary communities from early occupation to the later prehistoric era. Since the aim is to provide amo deled estimate for the age of thetransition from LNI to LNII at Tepe Chahar Boneh, and no single trench covers this transition, we have constructed a phase model consisting of a sequence of two phases (LNI and LNII), within which all dates from the same context were considered as sub-phases. Trench I covers the two main periods of the Early, Middle (Red slipped ware), and Late Bronze (Polychrome ware) and Iron Age. Because of the lack of charcoal samples, the team could not date the whole sequence of Trench II, but based on the ceramic sequence there is continuity of site occupation with the Kura-Arex ceramic types of burnished dark grey wares of the Early Bronze Age. Based on this observation, the cultural materials of Trench II at Tepe Shizar cover the Middle and Late Chalcolithic, and the Early Bronze Age. The Early Bronze age potteries are comparable with those in Ismaeil-Abad and Duran-Abad in Qazvin plain, Yanik and Haftovan in Northwestern Iran and Gurab, Godin IV and Pissa in Hamadan province. This single date (context 2034) is, however, at the base of the sequence, so the S boundary in the model gives a reasonable if poorly constrained estimate for the start of the LBA at this site - 2219 - 1554 cal BC at 95%, or 1841 - 1564 cal BC at 68%, with a median of 1730 cal BC.
