Producción y circulación de rocas verdes y sus produtos en el SW peninsular: el caso de Anta Grande do Zambujeiro

Abstract

In this work we focus on the general problems concerning SW Iberia Late Prehistory Green beads distribution. To accomplish this task we have characterised via XRF and XRD Green beads coming from megalithic structures and settlements and compared them with mineral data coming from Pico Centeno and Palazuelo de las Cuevas mining complexes. This study has shown that raw material selection during III millennium BCE for bead working in SW Iberia accounts several minerals (variscite, muscovite, talc, chlorite, …) which are exchanged as exotics in a regional and supra-regional scale.
