“…These sites display lithological variability and can be classified into two distinctive petrological groups: siliceous volcanic acid rocks and sedimentary detritic rocks formed through diagenetic silicification (Ramos Millán, 1997;Nocete et al, 2005;Martínez Fernández et al, 2006). Siliceous rocks of sedimentary origin can be found in several areas within the Betic Cordillera of southern Spain, which corresponds to the westernmost Alpine Mediterranean chain, occupying a belt ca.…”

Using ichnofossils to characterize chert tools: A preliminary study from Southern Iberia

Characterizing raw material of stone tools used by Late Neolithic and Copper Age communities is important for interpreting access to available sources and establishing regional routes of distribution. Ichnological analysis may be used to help characterize lithic material and determine the source of artifacts. Here we report for the first time the existence of trace fossils in artifacts from the Late Neolithic and Copper Age of southern Spain. Ichnological analysis indicates a trace fossil assemblage consisting of relatively scarce small‐sized Chondrites and abundant Phycosiphon. A regional survey of natural outcrops and chert quarries indicates the presence of discrete trace fossils only in the samples from geological formations that are part of the Campo de Gibraltar Complex. Ichnological composition in these samples is similar to that discerned in the artifacts and suggests that this was the probable source of the chert used in tool manufacture. © 2010 Wiley Periodicals, Inc.

The Guadiana Basin (SW Iberian Peninsula) is affected by acid mine drainage (AMD), a consequence of ancient mining activities in the Iberian Pyrite Belt (IPB). Consequently, the sediments at the Alqueva reservoir (SE Portugal) in the Guadiana Basin are potentially contaminated by trace elements, which make important: (i) to characterize the status of trace element pollution of the sediments; (ii) to evaluate the mobility and the bioavailability of As, Cd, Cu, Cr, Pb and Zn; and (iii) to assess the environmental risk associated with the total and bioavailable concentrations of trace elements, using the sediment quality guidelines (SQGs) and the risk assessment code (RAC). Metal enrichment factors (EF) and geoaccumulation indexes (I geo ), determined taking into account the regional background levels, revealed that, among the metals analyzed, Cd contributed the highest to pollution levels followed by Pb and As. Despite the trace element contamination of the Alqueva sediments, the sequential extraction showed that most of them are found in the oxidizable and residual fractions, which indicates that they are sparingly bioavailable, with exception of Cd (acid-labile fraction) and Pb (reducible fraction). Based on the RAC, Cd was the only metal that presented a high risk, while Pb, As and Zn showed a medium risk. Moreover, the SQGs revealed the existence of certain areas of extremely high risk, particularly related to high concentrations of total As and, in less extent, of Pb and Cd, associated with AMD, wastewater discharges and runoff of plant protection products from agricultural fields located near the reservoir.

“…En el sur de la Península Ibérica se pueden diferenciar tres importantes áreas donde abundan las rocas silíceas y en las que la investigación reciente ha avanzado en el reconocimiento y descripción de los afloramientos, así como en la caracterización de las zonas de talla y el desarrollo histórico de la producción con un "pico" en la intensificación de la manufactura de hojas prismáticas durante el Neolítico Reciente y el Calcolítico: 1) La Faja Pirítica Ibérica, de la que se han dado a conocer varios talleres de la provincia de Huelva Nocete Calvo et al, 2005). 2) El Subbético Medio, que es con diferencia la región donde se localizan los afloramientos más intensamente explotados durante la Prehistoria Reciente.…”

MENGA M01REVISTA ResumenEl encuentro del Grupo Europeo de Estudios Megalíticos celebrado en Sevilla en noviembre de 2008 reunió a un grupo internacional de especialistas para examinar dos temas: la presencia y significación de rocas raras, y la cronología de estos monumentos. Aunque se sabe que los monumentos megalíticos fueron construidos básicamente con piedras localmente disponibles, sus constructores incorporaron ocasionalmente bloques que habían sido traídos de más distancia. Estos ejemplos de "transporte megalítico" proporcionan datos respecto al significado tanto de las piedras en sí mismas como de sus fuentes de abastecimiento. Los monumentos neolíticos pueden también contener piedra "exótica" en forma de materiales especiales depositados con los muertos, indicadores de valores sociales y simbólicos. El segundo tema del encuentro, la cronología, trató del marco temporal en el que se construyeron los grupos individuales de monumentos así como de las perspectivas posibilitadas por programas de datación recientes. Entre estas perspectivas se encuentra el de...
