Archaeological record distribution analysis through stereophotogrammetric orientation calculation. The study case of Gombore II and Simbiro III Melka Kunture, Etiopia) [Analisi di distribuzione del record archeologico attraverso il calcolo degli orientamenti su base stereofotogrammetrica: il caso dei siti acheuleani di Gombore II e Simbiro III (Melka Kunture, Etiopia)]

Aim of this paper is to illustrate the utilize of the digital photogrammetry technique in order to reconstruct the depositional dynamics of the two contemporary acheulean (0,9-0,7 m/y BP) sites of Gombore II OAM and Simbiro III in the archaeological area of Melka Kunture (Ethiopia). Through stereographic projection a statistical analysis about the attitude of all the unmodified pebbles has been executed, and it permitted to identify, by density analyses, the presence of preferential depositional direction, that is in agreement with the previous geological reconstruction of the area. These analyses, integrated with a remote sensing study of the whole area, contribute to the archaeological and palaeoenvironmental recontruclion, necessary to better understand the evolution and the use of the landscape.
