Proveniências no Neolítico; arqueometria em contextos geológicos distintos

Abstract

O estudo de proveniências geológicas realizado em 3 áreas com contextos geológicos distintos - Lisboa, Freixo (Redondo) e Monforte, através da aplicação de diferentes metodologias e técnicas analíticas (DRX, ATG, FRX, ICP-MS, LA-ICP-MS, SEM-EDS, TIMS), permitiu verificar que a seleção dos esteios é condicionada pela diversidade e disponibilidade local dos materiais geológicos. O trabalho de campo desenvolvido a par com os dados obtidos (mineralógicos, petrográficos, geoquímicos, isotópicos) em amostras de antas e afloramentos indicam uma proveniência local para a generalidade dos esteios de antas das áreas de Lisboa e Freixo até 800 m, aumentando esta distância (1000-1700 m) na área de Monforte.

The study of geologic provenances conducted in 3 areas with different geological contexts - Lisbon, Freixo (Redondo) and Monforte, through the application of different methodologies and analytical techniques (XRD, TGA, XRF, ICP-MS, LA-ICP-MS, SEM -EDS, TIMS), has shown that the selection of slabs is conditioned by the diversity and local availability of geological materials. The developed fieldwork with the obtained data (mineralogical, petrographic, geochemical, isotopic) in samples of dolmens and outcrops indicate a local source for most of the slabs in the areas of Lisbon and Freixo up to 800 m, increasing this distance to 1000-1700 m in Monforte area.
