Proposta d'aplicació de la micromorfologia a l'estudi dels materials de construcció protohistòrics

With this article we present a methodology to study some materials little treated in the research, made until the present, of the protohistoric settlement of the peninsular northeast. We refer to the elements made from a mortar of soil (clay, slime, sand), mineral and vegetal components, without firing. This material, a lot used in the protohistoric architecture, is extremely fragile, and the number of retrieved rests is consequently really reduced. We want to add the perspective of the micromorphological analysis to the typological study. This technique consists on analyzing the sediment at scale microscopic. In this way we can gauge the composition and elaboration to the different building materials, as well as to distinguish the pedosedimentary post-depositional processes that they affect to the preservation and conservation of the same ones. As a starting point we focus on the materials retrieved in the site of Sant Jaume-Mas d'en Serra (Alcanar, Montsia), dated in the transition of the 7th centuries to 6th BC.
