Ocre, hematites y óxido de hierro: el problema terminológico

Iron oxides are virtually omnipresent when analyzing contexts, not only referring to rock art, but also related to a whole series of activities, which we could consider as quotidian for prehistoric environments. Nevertheless, a systematic study of these has not started until recent times. As a result, it could be argued that a part of archaeological literature, not specialized on pigmentology, shows sometimes a certain lack of terminological accurateness. With this document we mean to, through an analysis both of the functioning and the geochemical and mineralogical properties of ochre, hematite and iron oxides themselves, expose the need for an appropriate terminology, as well as to show the problems derived from an inadequate naming. Finally, we bring some proposals, which could maybe help on an appropriate terminological standardization.
