Metallic nanoparticle enrichment at low temperature, shallow CO2 seeps in Southern Italy
2012
We report on metal enrichment along a natural pH gradient owing to increased CO2 degassing at cold, shallow seeps of Vulcano Island in the Mediterranean Sea, off Sicily. We assessed composition of unfiltered and filtered seawater (<100 nm) along acidic zones ranging between ambient and pH 5, and showed that most seep derived elements are present as nanoclusters which then aggregate into larger colloids while mixing with ambient seawater along a pH gradient. Size and elemental composition of such naturally occurring nanoparticles assessed by modern characterisation methods were in good agreement with the results from conventional analytical methods. We provide analytical evidence for the pre…
Complex adaptative systems and computational simulation in Archaeology
2017
Traditionally the concept of ‘complexity’ is used as a synonym for ‘complex society’, i.e., human groups with characteristics such as urbanism, inequalities, and hierarchy. The introduction of Nonlinear Systems and Complex Adaptive Systems to the discipline of archaeology has nuanced this concept. This theoretical turn has led to the rise of modelling as a method of analysis of historical processes. This work has a twofold objective: to present the theoretical current characterized by generative thinking in archaeology and to present a concrete application of agent-based modelling to an archaeological problem: the dispersal of the first ceramic production in the western Mediterranean.
Pantellerian ware: a comprehensive archaeometric review.
2007
Pantellerian ware is a Late Roman cooking ware whose production centre was established on the island of Pantelleria by the pioneering research of Fulford and Peacock almost 20 years ago (Peacock 1982; Fulford and Peacock 1984). Archaeological and archaeometric studies carried out by the authors of the present contribution during the past four years have aimed to fully characterize this ceramic class. Recurrent ceramic forms, their distribution over time and space, their petrographic characteristics and their chemical identity, as well as possible raw materials and their technological properties, were considered. The present paper is a comprehensive review of this archaeometric work and aims…

La placa grabada de Balma Guilanyà (Prepirineo de Lleida) y las manifestaciones artísticas del Mesolítico de la Península Ibérica
2011
A carved rock with geometric and/or abstract signs discovered at the Balma Guilanyà site has made possible the analysis of the artistic patterns developed after the end of the Upper Palaeolithic in the Iberian Mediterranean region. Archaeo-stratigraphic, chronometric and chrono-cultural attributes link this finding to the Mesolithic, probably during the tenth millennium cal BP. Graphic analysis and the comparison with different kinds of representations from this same area allows the evaluation of the problematic that surrounds the characterization of West Mediterranean Mesolithic art.
A mediterranean perspective of the neolithization process. The cave of Nerja in the context of andalusia (Spain)
2013
[EN] This paper offers an overview for the Early Neolithic of the southern coast of Andalusia (Spain). Analyses of materials recovered during the 1979-87 excavations in Nerja cave by professor Francisco Jordá Cerdá, including new radiocarbon dates on domestic taxa, allow us to examine the Mesolithic-Neolithic transition. Paleoenvironmental and paleoeconomic data (stratigraphy and bioarcheological data) combined with archaeological data (ornaments, bone tools, lithics, and ceramics were analysed) to provide a regional perspective on the neolithisation of the western Mediterranean. There is an apparent 500-year gap between occupations by the last coastal foragers and the earliest Neolithic fa…
Episodios de precipitación torrencial en el este y sureste ibéricos y su relación con la variabilidad intraanual de la oscilación del Mediterráneo oc…
2018
Ponencia presentada en: XI Congreso de la Asociación Española de Climatología celebrado en Cartagena entre el 17 y el 19 de octubre de 2018. [ES]La relación de la Oscilación del Mediterráneo Occidental (WeMO) con la ocurrencia e intensidad de las precipitaciones en el litoral mediterráneo ibérico ha sido demostrada en numerosos trabajos. Entre 1950 y 2016 se registraron 239 episodios de precipitación torrencial extrema (≥200 mm/24 horas) en las cuencas hidrográficas del Júcar y del Segura (3,6 casos al año). El 29,3% de estos eventos tuvieron lugar con una fase de la WeMO fuertemente negativa, el 37,5% en una fase negativa y el 28,3% en una fase ligeramente negativa. Solo el 7,9% de los epi…
Combined spatial Radiocarbon density maps and refined SCPD method to explore food production spread through the central and western mediterranean
2018
The neolithisation process in Europe constitutes a fundamental issue of interest in social evolutionary studies. The pioneer work of Ammerman and Cavalli-Sforza (1984) has been considered the basis for discussing the mechanisms involved in the expansion of farming and herding practices in a continental scale, assuming their spread from the Near East domestic core area. From an evolutionary perspective the introduction of agriculture and livestock implies major shifts in social dynamics including changes in demographic patterns as well as in settlement distribution and cultural models. Spatial analysis together with the use of radiocarbon data as a demographic proxy maybe one of the keys to …
Landscape Socioecology in the Serpis Valley (10,000–4000 BP)
2008
En este trabajo se discute nuestro enfoque de la modelización del paisaje para la cuenca del Serpis medio (costa mediterránea central de la Península Ibérica) durante el Holoceno. La secuencia arqueológica de estos valles está marcada por la aparición inicial del paquete neolítico alrededor del año 5700 a.C. Examinamos cómo los paisajes responden al modo de vida agrícola, tanto a corto como a largo plazo. Conceptos como el cambio, la adaptación y también la resiliencia proporcionan marcos conceptuales para comprender mejor la forma en que los seres humanos interactúan con su entorno. También ayudan a explicar cómo fenómenos como la introducción inicial de la horticultura simple de cereales …
