Aportació dels estudis de fitòlits en la prehistòria: formació, metodologia i casos d’estudi
Resum
En els darrers anys els estudis de microfòssils vegetals i els fitòlits en particular s’han consolidat com una eina indispensable per a la reconstrucció de les condicions paleoambientals i la paleovegetació, com també per traçar la utilització i l’explotació dels recursos vegetals en el passat. En aquest treball s’aborden diferents qüestions metodològiques considerant el procés de formació, composició, producció i preservació d’aquestes microrestes. Així mateix s’incideix en la importància d’entendre tant els processos de formació com els processos postdeposicionals que poden haver afectat la preservació de les restes i que són crucials en la interpretació del registre arqueològic. A través d’una selecció de casos d’estudi articulats en tres eixos principals (reconstrucció de paleovegetació, ús del foc i primeres pràctiques agrícoles i ramaderes), es demostra el gran potencial i variabilitat de les aplicacions.Paraules clau
