Pinturas rupestres de la cueva de "La Graja". Caracterización de pigmentos y análisis digital de imágenes

Abstract

[ES] La presente investigación forma parte de un estudio amplio desarrollado en torno a un conjunto de yacimientos arqueológicos localizados en la Comunidad Autónoma de Andalucía y que tenía como objetivo fundamental el conocimiento de dichos yacimientos dentro de los contextos geomorfológico, biológico y climático. En este caso concreto se abordó el estudio relativo a los procesos de alteración de las pinturas rupestres que se encuentran en la cueva de "La Graja "(provincia de Jaén). Dichos procesos, se ha concluido que están relacionados principalmente con la alta disponibilidad de agua en su zona de ubicación. La composición de las pinturas no es lo que usualmente se encuentra en otros abrigos estudiados con anterioridad, en donde predominan los óxidos de hierro. La presencia de óxidos de cobre, titanio y cerio indican un alejamiento de la tónica común que se da en las pinturas rupestres andaluzas.

[EN] The present study is part of a wide-ranging research on a group of archaeological sites located in Andalucía (Spain) whose main aim was a better understanding of these sites within a geomorphological, biological and climatic context. This specific investigation concerns the alteration processes affecting the rupestral paintings found in the cave of "La Graja". It has been concluded that such processes are related mainly to the high availability of water at the site's location. The paint's composition diverges from that usually encountered in other, previously studied shelters, where iron oxides have been found to prevail. The presence of copper oxides, titanium and cerium represents a departure from the common findings in Andalusian rupestral paintings.

Los autores desean expresar su agradecimiento a la Consejería de Cultura de la Junta de Andalucía por la financiación de los trabajos que han dado lugar a la presente publicación.
