A1 Tomás, Roberto A1 Marco Molina, J. A. AB The Partagat chasms, located at the highest part of the Sierra de Aitana (Province of Alicante), are largejoints which have opened up in Eocene limestone. They measure up to 15-20 metres in width and dozensof metres in depth. These joints have originated from lateral-spreading, which have evolved with time intoslides. They have formed here along the lines of pre-existing NW-SE and NE-SW fractures, due to themovement of large blocks of limestone over an underlying layer of marls, both Eocene in age. Throughoutthe Quartenary, these landslides caused the mountain front retreat of the Aitana fault, a normal E-W faultwith a throw of several hundred metres YR 2006 FD 2006 LK http://hdl.handle.net/10272/8613 UL http://hdl.handle.net/10272/8613 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
