Statistical analysis on metric and geometric features of dolmens in the Gor river megalithic landscape (Granada, Andalusia, Spain)

The construction of dolmens took place in Europe from the Neolithic to Early Bronze Age (fifth millennium BC–second BC) and had a rapid development along Atlantic façade, with an important focus Andalusia. Within this area, megalithic necropolises located banks Gor River (Granada, Andalusia, Spain) are studied. In paper, multivariate techniques applied characterize associated river landscape by means two analyses. First, new classification using their location variables produces optimal number 8 necropolis instead traditional 11. addition, improves spatial division because there is no overlapping between necropolises. Secondly, analysis dimensional variables, which aims detect possible constructional patterns, performed obtaining three main grouping. first two, length width chamber, can be summarized as area chamber and, terms this, classified into groups. third one, corridor, considered factor for intragroup discrimination.
