Slope deposits, in semiarid regions, are known to be very sensitive environments, especially those that occurred during the minor fluctuations of the late Holocene. In this paper we analyse Holocene colluvium genesis, composition, and paleoenvironmental meaning through the study of slope deposits at Peña Enroque (Ebro Depression, NE Spain). Two cumulative slope stages are described during this period in NE Spain. Both slope accumulations are superimposed and this has enabled an excellent preservation of the aggregative sequence and the paleosols corresponding to stabilisation stages. 14 C and TL dating, as well as archaeological remains, provide considerable chronological precision for this sequence. The origin of the accumulation of the lower unit is placed around 4295-4083 cal yr BP/2346-2134 cal yr BC (late Chalcolithic) and it developed until the Iron Age in a cooler and wetter climate (Cold Iron Age). Under favourable conditions, a soil A-horizon was formed on top of this unit. After a long erosive stage (Warm Roman Period, Medieval Climatic Anomaly), a new slope accumulation was formed during the Little Ice Age. Within the slope two morphogenetic periods are distinguished, both ending with A-horizons. Both periods can be related with the two main cold-wet climatic events in NE Spain.
En este artículo se analizan las tendencias actuales respecto a la utilización de la tecnología digital en torno a la arqueología y la educación patrimonial. El estudio parte de un análisis sobre el potencial educativo de la arqueología y se concreta posteriormente en la aplicación didáctica de los modelos digitales de reconstrucción e interpretación de espacios y objetos arqueológicos. El trabajo permite establecer tres líneas básicas de innovación educativa: modelos inmersivos en realidad virtual, entornos de interacción social web 2.0 y mobile learning, además de una línea de investigación emergente vinculada a la evaluación de proyectos y materiales patrimoniales basados en las tecnologías digitales. En el trabajo, se plasman los resultados de varias investigaciones originales comdesarrolladas por las autoras del texto con el respaldo de proyectos de investigación competitivos, al igual que se hace referencia a otros proyectos y experiencias.
