Graffiti rupestres de época histórica en la Montaña de Alicante: una manifestación artística popular olvidada

Desde hace algunas décadas, se ha tratado de llamar la atención sobre un tipo de patrimonio apenas conocido. Son los denominados graffiti -entendidos como escritos o dibujos antiguos-, que han sido poco valorados como objeto de investigación, probablemente debido a que la mayoría de las representaciones son de cronología histórica. Este patrimonio ignorado sorprende, sin embargo, por la profusión con la que aparece no sólo en las paredes de edificaciones históricas, sino también en los abrigos y cuevas de nuestra geografía. Unas representaciones que, a nuestro juicio, cambian la manera que tenemos de entender las relaciones de la gente con su entorno.For several decades, researchers have tried to draw attention to a little-known type of heritage. This is the graffiti, understood as ancient writings or drawings, which have been undervalued as a research object, probably because most of representations have historical chronology. Surprisely, this ignored heritage profusely appears not only on the walls of historic buildings, but also in the shelters and caves of our geography. These representations, in our view, change the way we understand the relationships between people and their environment

Secondary flow in contour currents controls the formation of moat-drift contourite systems

Ocean currents control seafloor morphology and the transport of sediments, organic carbon, nutrients, and pollutants in deep-water environments. A better connection between sedimentary deposits formed by bottom currents (contourites) and hydrodynamics is necessary to improve reconstructions of paleocurrent and sediment transport pathways. Here we use physical modeling in a three-dimensional flume tank to analyse the morphology and hydrodynamics of a self-emerging contourite system. The sedimentary features that developed on a flat surface parallel to a slope are an elongated depression (moat) and an associated sediment accumulation (drift). The moat-drift system can only form in the presence of a secondary flow near the seafloor that transports sediment from the slope toward the drift. The secondary flow increases with higher speeds and steeper slopes, leading to steeper adjacent drifts. This study shows how bottom currents shape the morphology of the moat-drift system and highlights their potential to estimate paleo-ocean current strength.Projekt DEALBremenIDEA University of Breme

A paucity of examples in the ancient record and the lack of consensus on diagnostic criteria for differentiating them from other deepwater deposits limit our understanding of how they may record past global oceanic circulation, tectonic events and gateway evolution. This work describes an exceptional example of Eocene to middle Miocene deep-marine deposits located both onshore and offshore deepwater environments around the island of Cyprus. Multidisciplinary approaches were used to discriminate contourite facies associations, propose a sedimentary model, and interpret the relations with regional tectonics and the evolution of the nearby Indian Gateway. Contourite deposits appear in late Eocene to middle Miocene intervals interstratified with pelagic/hemipelagic sediments, turbidites and mass-transport deposits (MTDs). These deepwater deposits developed along a slope basin located on the upper plate of an active margin, evolving from a wide basin formed during a period of tectonic quiescent into a series of shallowing-upward, segmented sub-basins affected by compressional stress. The present study proposes a sedimentary model in which two contourite depositional systems developed: first in the Eocene (dominated by finer-grained contourites), and then during the latest Oligocene to middle Miocene (dominated by coarser-grained contourites). Both systems were buried by extensive marl deposits and record the respective influence of deep (circulating NW) and intermediate (circulating SE) water masses. The long-term evolution of the contourites reflects tectonic events that enhanced subduction processes south of Cyprus as well as exchange between the Neotethys Ocean and the Indian and Atlantic Oceans —until the final closure of the Indian Gateway by the end of the middle Miocene, when a new circulation pattern was established with the formation of the Mediterranean Sea. The contourites described here represent bi-gradational sequences that normally form in association with contouritic drifts, sometimes having the asymmetric top-cut sequence characteristics of plastered drifts and contourite terraces. The coarser (sandy) contourites, formed from the latest Oligocene to middle Miocene, consist of three packages associated with compressive and flexural phases. They pertain to I) Chattian (late Oligocene); II) Aquitanian/Burdigalian (early Miocene) and III) Langhian (middle Miocene). Evidence of enhanced bottom current episodes occurs toward the top of these packages before they are buried by later dominant marl deposits. The sandy contourites thus formed during the compressive phases, whereas the predominately finer-grained units formed during later flexural phases. The intermittent turbidites and MTDs (developed during compressional phases in combination with pelagic/hemipelagic sediments) represent the sediment supply for the contourite deposits after their winnowing and / or reworking. Our research found that the diagnostic criteria for discriminating ancient bottom current deposits from other deepwater deposits are related primarily to variations in sedimentary processes, current behaviour and its velocity, sedimentation rates and paleoenvironmental conditions. This highlights the importance of primary sedimentary structures, microfacies and ichnological features in making determinations at the sedimentary facies scale. Due to their common occurrence, sedimentary thickness (30-40 m), potential porosity and permeability, sandy contourites can form deepwater reservoirs for energy geosciences. In summary, this work demonstrates the role of plate tectonics and oceanic gateways in driving the paleo-oceanic circulation that, in turn, controls sedimentary processes and shapes the morphology of oceanic basins and continental margins. It also allows for comparison with other present-day and ancient continental margin deposits. Future high-resolution approaches and analyses of other geological settings could help resolve the sedimentary architectures of similar deepwater systems in terms of episodic tectonic processes —involving compressive-flexural stress variations. They control the Earth’s surface environment (sea-level, climate and oceanic circulation) over time by influencing sediment supply, packages of strata and types of contourite deposits.Joint Industry Project (JIP) supported by BP (United Kingdom), ENI (Italy), TOTAL (France), ExxonMobil (United States), Wintershall Dea (Germany) and TGS (United Kingdom) within the framework of “The Drifters” Research Group at Royal Holloway University of London (RHUL), and it is related to the projects CTM 2012-39599-C03, CGL2016-80445-R and CTM2016- 75129-C3-1-RDeutsche Forschungsgemeinschaft (DFG) is gratefully acknowledged (HU 804/11-1

Grabados rupestres del Cantalar (Tibi, Alicante)

El presente artículo pretende dar a conocer una serie de conjuntos de grabados rupestres aparecidos en el término municipal de Tibi (Alicante). Éstos comparten estructura básica, si no funcionalidad, con los observados en muchos enclaves de toda la fachada mediterránea y el interior de la Península Ibérica. Se trata por un lado de cazoletas de reducido tamaño a las cuáles vierten canalillos de distintas morfologías, apareciendo algunas de ellas en el contexto de un poblado de la Edad del Bronce. Por otro lado encontramos motivos cruciformes, los cuales asociamos a momentos históricos.This paper tries to present a set of rock engravings appeared in Tibi (Alicante). They share basic structure, if not functionality, with those observed in many locations throughout the Mediterranean facade and interior of the Iberian Peninsula. Those are, on the one hand, small cupules carved in the rock to what dumped gutters of different morphologies, some of them appearing in the context of a settlement of the Bronze Age. On the other hand we find cruciform motifs, which we associate with historical moments
