| Sumario: | We carried out a detailed paleomagnetic survey at the Dmanissi archeological site (Republic of Georgia, Caucasus) in orderto clarify the relative position of the site in the Plio-Pleistocene chronologic framework. In total, 27 standard paleomagnetic coreswere obtained across the profile at the locality where the human mandible was found. Fifteen characteristic remanent magnetizationdirections have been used to determine the magnetic polarity of the studied units. The presence of a strong normal overprintis evident in most of the samples and is usually removed at about 250 degrees Celsius. Judging from the paleomagnetic analysis,it seems that the sediments containing the hominid and stone tools all show reverse polarity magnetization. This points to Matuyamaage (post-Olduvai) for the site, in disagreement with previous studies. |
