The stone age Dolgoe 11 site in the Savinskiy district, Ivanovo region: first results of dating by the optically simulated luminescence method

The article discusses the results of the interdisciplinary study of the presently little-known Dolgoe 11 archaeological site. The materials of the lithological description of the section, detailed characteristics of the structure of paleosols, the positions of clearly distinguished two cultural layers are given. Archaeological materials from the upper and lower cultural layers are very different from each other, both in the raw materials used for their shaping, and in typological and technological characteristics. The absolute chronology from OSL dating allows determine the age of the lower cultural horizon about 13,5–14 thousand years ago. The settlement of humans in the area of the site occurred under the conditions of Allerod warming, therefore, this cultural layer is correlated with Paleolithic. The upper cultural horizon was formed already in the Holocene – in the Mesolithic era (about 9 thousand years ago), during relief stabilisation due to the widespread development of vegetation.
