Abstract(s)
O estudo consiste na caracterização do espólio metálico das necrópoles de cistas de Casa Velhas e da Provença. Os artefactos de base cobre são compostos por cobre arsenical (2,03-5,64% As), exceptuando-se um “anzol” em bronze, liga que constitui uma das inovações do Bronze Pleno do Sudoeste, tal como a prata, aqui utilizada em ornamentos: anel (99,7% Ag) e bracelete (94,5% Ag; 5,41% Cu). Uma conta em ouro (12,6% Ag; <0,04% Cu) terá sido manufacturada em ouro de aluvião, tal como a maioria dos ouros pré-históricos. Por último, integram-se os resultados na metalurgia no sul de Portugal durante o II milénio a.C.
The characterisation of Middle Bronze Age metals of cists at Casa Velhas and Provença is presented. Copper-based artefacts are made of arsenical copper (2.03-5.64% As), excluding a bronze “fishhook” highlighting a metallurgical innovation in the Southwestern Iberian Peninsula, similarly to the silver used in ornaments, namely a ring (99.7% Ag) and a bracelet (94.5% Ag; 5.41% Cu). There is also a gold bead (12.6% Ag; <0.04% Cu) probably from alluvial nuggets, as the majority of prehistoric gold. Finally, the results are compared with the known metallurgy from the 2nd millennium BC in southern Portugal.
