Variscita y ámbar en el Neolítico gallego. Análisis arqueométrico del collar del túmulo 1 de Chousa Nova, Silleda (Pontevedra, España)

Abstract

La excavación del túmulo 1 de Chousa Nova, Silleda (Pontevedra), proporcionó unos resultados sorprendentes. Aunque muy deteriorado, por diferentes factores, conservaba evidencias de una gran complejidad constructiva. Dentro de su cámara megalítica apareció, junto con otros objetos pulidos, un conjunto de 35 cuentas dispuestas a modo de collar. Se han estudiado todas, unas de color verde y otras de carácter orgánico, intercaladas entre ellas. Los resultados del análisis arqueométrico mediante técnicas no-destructivas (difracción y fluorescencia de Rayos X, espectroscopía de infrarrojos, microscopía óptica y electrónica de barrido ambiental, con microanálisis) muestran una naturaleza mineralógica basada en la variscita y el ámbar, así como unas características texturales y composicionales muy similares entre cada conjunto. Se ha determinado y cuantificado asimismo la importancia de los fenómenos de alteración y disolución de estos objetos, debido a un ataque químico intenso durante el período de enterramiento. Se discuten las posibles áreas fuente de procedencia de dichos materiales, en base a los datos geoquímicos obtenidos.
