Correlation on geochemical evidence of the stratigraphic profiles at the Darvagchai-zaliv-1 site

We present here the preliminary results of field and lab research, provided in cultural chronological Middle Paleolithic complexes of Darvagchai-zaliv-1 site. A few Paleolithic occurrences is located in area near Darvagchai-zaliv-1, on the coasts of Gedzhukhskoe reservoir. All of them are confined to stiff coastal slopes and bank cutting with seaside-marine and continental sediments up-section. The studied outlier of third Paleo-Caspian terrace has the complicated geology aspects. When it had been formed as well as during the post-sedimentological period the range of geological processes have happened. They significantly complicated the chronological comparison between obtained stratigraphic profiles and lithic collections respectively. The sedimentological conditions directly reflect on micro-component deposit composition and we can purpose that microelement distribution will be similar in similar conditions. The research was aimed to compare stratigraphic cross-section of pit 1, which is situated in the top of Paleo-Caspian terrace outlier, and stratigraphic cross section of pit 2, which is situated in its bottom. Also, we purposed to explore how the sedimentation developed in this parts of terrace: did they are synchronous or not. We studied the microelement composition of these geological deposits and correlated the upper and lower profiles on geochemical evidence. Wide range of studied elements permitted to educe the geochemical correlation between stratigraphic profiles of both pits and make some conclusions about the character of element transportation and accumulation. The massive material formed the upper and lower part of the site, has the homogenous chemical composition. The stratigraphic correlation of geochemical data shew that profiles match with so-and-so 80 % agreement according their microelement composition. The correlation parameters evaluated layer-by-layer show that sedimentation accumulated in the similar conditions in the both profiles.
