Resumen
Se presentan los avances en el estudio del arte rupestre en un sector ubicado al norte del Lago Traful, a partir de la aplicación de diferentes técnicas arqueométricas. Se utilizaron análisis físico químicos: difracción de rayos X y microespectroscopia Raman, complementados con análisis elementales para determinar los cromóforos en clastos recuperados en excavación, en recolecciones superficiales en cercanía a los sitios y en pinturas rupestres. Por otra parte, se aplicaron técnicas de información geográfica para diseñar modelos de circulación e intercambio de información a nivel regional. Se hallaron minerales a base de hierro en muestras de color verde, rojo y amarillo; y hueso calcinado y calcita en muestras blancas.
This work shows some advances in the study of rock art in Lago Traful area applying archaeometric techniques. Physicochemical studies such as X-ray diffraction and Raman microspectroscopy, together with elementary analysis, were used to identify chromophores in mineral clasts recovered in archeological excavation and in superficial survey collections near the sites as well as on shelter art paintings. On the other hand, geographic information techniques were applied to design models about the circulation and exchange of information at the regional level. Iron based minerals were identified on green, red and yellow colored samples; calcined bones and calcite were found on white ones.
