Abstract: The origin of iron-oxide materials found at Paleolithic and Neolithic sites in the Spanish Mediterranean region is a pivotal issue that has not yet been explored. The aim of this study is to investigate the exploitation of local ochre sources during the different archaeological phases identified at the site of Coves de Santa Maira (Valencian Region, Eastern Spain). A sampling strategy and a methodological approach were developed. Lumps of ochre and raw materials were sampled from the archaeological site and its surroundings. The archaeological materials studied are from the occupational phases dated to between 15 and 6 ka cal BP, whereas the raw materials sampled from the surroundings of the cave are red fine-grained and earthy-grained sedimentary materials and Late Triassic (Keuper) clays. Morphological, mineralogical, and chemical analyses of the samples were carried out, and quantitative data on ochre fragments and processing tools recovered at the site were also included. Finally, Fe-normalized and log10 transformed data and multivariate statistical analysis, using major, trace, and rare earth elements as variables, were applied to compare the mineralogical and chemical profiles of the archaeological materials with those from geological sources. The results obtained have provided interesting data about iron-based mineral exploitation during Prehistory in the studied region.
