“…Therefore, late Miocene mantle‐source volcanic rocks intruded across this major fault [ Pérez‐Valera et al ., ]. Although there is no related instrumental seismicity, paleoseismic studies suggest that the Socovos fault may be responsible for moderate earthquakes during the Holocene [ Sánchez‐Gómez et al ., ].…”

We examine the late Tortonian to present‐day deformation of an active seismic sector of the eastern Iberian foreland basement of the Betic Cordillera, in southern Spain. Transpressive faults affecting Paleozoic basement offset up to Triassic rocks. Late Triassic clays and evaporites constitute a décollement level decoupling the basement rocks and a ~100 m thick cover of Jurassic carbonates. Monoclines trending NE‐SW to ENE‐WSW deform the Jurassic cover driven by the propagation of high‐angle transpressive right‐lateral basement faults. They favor the migration of clays and evaporites toward the propagated fault tip, i.e., the core of the anticline, resulting in fluid overpressure, fluid flow, and precipitation of fibrous gypsum parallel to a vertical σ3. The overall geometry of the studied monoclines, as well as the intense deformation within the clays and evaporites, reproduces three‐layer discrete element models entailing a weak middle unit sandwiched between strong layers. Late Tortonian syn‐folding sediments recorded the initial stages of the fault‐propagation folding. Equivalent unexposed transpressive structures and associated monoclines reactivated under the present‐day NW‐SE convergence are recognized and analyzed in the Sabiote‐Torreperogil region, using seismic reflection, gravity, and borehole data. A seismic series of more than 2100 low‐magnitude earthquakes was recorded within a very limited area of the basement of this sector from October 2012 to May 2013. Seismic activity within a major NE‐SW trending transpressive basement fault plane stimulated rupture along a subsidiary E‐W (~N95°E) strike‐slip relay fault. The biggest event (mbLg 3.9, MW 3.7) occurred at the junction between them in a transpressive relay sector.

“…The obtained data improve the knowledge on the neotectonic system of the eastern Betics, which in turn helps to understand the landscape evolution and contributes to earthquake hazard assessment in the wider area (e.g. Sánchez-Gómez et al, 2011). Our inferences have implications for the evolution of the Segura river basin, which is not well studied in this area.…”

“…Silva et al, 1993). The first area of faulting consists of three NW-SE-oriented dextral strikeslip faults active up to the Holocene and linked to moderate seismic activity (Rodríguez-Pascua et al, 2008Sánchez-Gómez et al, 2011). The Socovos fault is the most prominent structure of the CAA zone, and the most significant fault at a regional scale (e.g.…”

“…La fase neolítica fue definida como los niveles v y vi; de este último, se obtuvo una datación sobre carbón vegetal de un hogar de 6260 ± 120 bp (Martínez Sánchez, 1994) que calibrado a 2 σ se situaría entre el 5476-4938 bc y la media en el 5206 ± 143 bc 4 . En un trabajo reciente sobre un seísmo en el abrigo también se han obtenido dataciones absolutas, pero para un momento avanzado del Neolítico (5980 ± 50 bp y 5820 ± 50 bp) cuyas medias son 4873 ± 63 bc y 4676 ± 65 (2 σ) respectivamente (Sánchez-Gómez et al, 2011). El material neolítico está formado por cerámica, elementos de sílex, cuarcita y brazaletes de caliza blanca.…”

) LXXIV, julio-diciembre; Resumen: Se estudia un conjunto de brazaletes de piedra, acabados y en proceso de elaboración, de la Cueva-Sima de La Serreta, así como los útiles y técnicas empleados en el proceso de manufactura. La metodología de trabajo se ha basado en el estudio tecnológico, traceológico y tipológico de los restos de elaboración y los productos manufacturados. El análisis de este registro material ha permitido extraer conclusiones sobre el uso de la cueva y su ocupación. La extracción de roca de la pared de la cavidad afectó a una de las pinturas rupestres, lo que nos ha permitido determinar que la cronología de las pinturas puede ser anterior o sincrónica a la artesanía de los brazaletes. De igual forma, la identificación de las técnicas que componen la cadena operativa de elaboración de los brazaletes de piedra ha permitido reconocer procedimientos propios y particulares de este taller que lo diferencian del resto de los estudiados. La situación geográfica del taller de La Serreta viene a remarcar las relaciones culturales entre poblaciones neolíticas del Sur y el Levante de Iberia.Palabras clave: Neolítico; Adornos; Taller; Artesanos; Cadena operativa.Abstract: We study a set of stone bracelets, finished and in process, from the Cueva-Sima de La Serreta, as well as the tools and techniques used in the manufacturing process. The working methodology is based on technological, use-wear and typological analysis of manufacture residues and finished product. The study of this material record has allowed conclusions about the use of the cave and occupation. The rock extraction of the cavity wall affected a rock paintings. It has allowed us to determine the chronology of the paintings may be earlier or synchronous to the crafts of the of the bracelets. Likewise, identifying techniques that make up the operational chain of processing stone bracelets, has led a recognition own features of this workshop that differ from the rest of workshops studied. The geographical location of La Serreta workshop is to highlight cultural relations between Neolithic populations of the South and the East of Iberia.
