RT Journal Article T1 Los procesos de alteración de las rocas soporte de las pinturas de los conjuntos rupestres del Tajo de las Figuras (Cádiz) y Peñas Cabreras (Málaga) T1 Alteration processes in host-rock with paintings from Tajo de las Figuras (Cádiz) and Peñas Cabreras (Málaga) prehistoric-art sites A1 Sánchez Moral, S. A1 Cañaveras, J.C. A1 Hoyos, M. A1 Sanz Rubio, E. AB The sandstones which are the host wall-rock for prehistoric-art representations in Tajo Figuras (Cádiz) and Peñas Cabreras (Málaga) prehistoric-art sites show extensive alteration features damaging the paintings and engravings. These features include alteration crusts, detachment of rock-plates, alveolar surfaces and grainificalion. Climatic and geomorphic conditions, together with the compositional characteristics of the sandstones are thought to be the main factors responsible of these alteration features PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12808 UL http://hdl.handle.net/10272/12808 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 15 jun 2026
