Chronologie et périodisation des campaniformes en France méditerranéenne
2012
What is the current state of research, twenty years after the Ambérieu-en-Bugey colloquium, regarding the chronological setitng of the Bell Beaker horizon, the periodisation of pottery styles and the relationships between Bell Beakers and local groups in the late Neolithic in Mediterranean France ? A brief inventory of knowledge from 1992 together with research from the last two decades will allow us to re-evaluate stratigraphic evidence and radiocarbon dates and to examine the evolution of sttlement distribution and the artefact contexts and associations
Chapter 5 : The Beaker Transition in Mediterranean France
2010
In Mediterranean France, the end of the Neolithic is now wellknown. Many cultural groups are chronologically and geographically defined (Rhône-Ouvèze, Fontbouisse, Vérazien...) and the origin of the Beakers phenomenon seems clearly foreign in this context. The existence of this cultural variety in the Final Neolithic leads to: Differences in the first Beaker settlements in these areas, Various types of acculturation, partial or total, of the indigenous groups, with sometimes the survival of certain Late Neolithic traditions, The development of two Middle regional Bell Beakers groups (Pyrenean group and Rhodano-Provençal Group) after the first phenomenon. The beaker pots known on several hun…
A method of data structuring for the study of diffusion processes of raw materials and manufactured objects
2017
International audience; Workgroup 3 of the ArchaeDyn II programme aims at studying the diffusion systems of products in ancient times. In order to be able to structure data in GIS in an appropriate way, we propose to go through three levels of modelling: the first one aims at gathering together the different components of the diffusion systems taking into account their interactions; the second corresponds to a conceptual data model created with the help of the HBDS method, that will, as we get to the third stage, lead to the creation of a "three-dimensional" geodatabase. Here we point out the fact that the approach through the simple notion of “site” is not sufficient to study the products’…

New perspectives on the human occupation of the Gulf of Palermo during the Metal Ages: the funerary cave of Zubbio di Cozzo San Pietro (Bagheria) and…
2020
Abstract The Archaeological Superintendency of Palermo (Sicily), with the chair of Anthropology at the University of Palermo, carried out a preliminary investigation in the Zubbio of Cozzo San Pietro (Bagheria) – a cave known so far only from a speleological point of view - which proved to be a funerary cave dating to the Copper/Bronze Age. In the course of archaeological work during the installation of the electricity grid in the Mondello area (Palermo), part of a necropolis consisting of three oven-shaped tombs was exposed. The tombs multiple depositions, whose remains were found in a very bad state of preservation. Based on the type of funerary structures and the equipment found in them,…
Sourcing african ivory in chalcolithic Portugal
2009
A recent review of all ivory from excavations in Chalcolithic and Beaker period Iberia shows a marked coastal distribution – which strongly suggests that the material is being brought in by sea. Using microscopy and spectroscopy, the authors were able to distinguish ivories from extinct Pleistocene elephants, Asian elephants and, mostly, from African elephants of the savannah type. This all speaks of a lively ocean trade in the first half of the third millennium BC, between the Iberian Peninsula and the north-west of Africa and perhaps deeper still into the continent.
Poggetti Vecchi (Tuscany, Italy): A late Middle Pleistocene case of human-elephant interaction
2019
Abstract A paleosurface with a concentration of wooden-, bone-, and stone-tools interspersed among an accumulation of fossil bones, largely belonging to the straight-tusked elephant Palaeoloxodon antiquus, was found at the bottom of a pool, fed by hot springs, that was excavated at Poggetti Vecchi, near Grosseto (Tuscany, Italy). The site is radiometrically dated to the late Middle Pleistocene, around 171,000 years BP. Notable is the association of the artifacts with the elephant bones, and in particular the presence of digging sticks made from boxwood (Buxus sp.). Although stone tools show evidence of use mainly on animal tissues, indicating some form of interaction between hominins and an…
Holocene climate variability in Sicily from a discontinuous stalagmite record and the Mesolithic to Neolithic transition
2006
AbstractFabric and stable isotopic composition of a Holocene stalagmite (CR1) from a cave in northern Sicily record changes in paleorainfall in the early Holocene. High δ13C stable isotope values in the calcite deposited from ca. 8500 to ca. 7500 yr ago are interpreted as reflecting periods of high rainfall. The wet phase was interrupted by two periods of multi-century duration characterized by relatively cool and dry winters centered at ca. 8200 and ca. 7500 yr ago, highlighted by low δ13C and δ18O values. A high variability of δ13C values is recorded from ca. 7500 to ca. 6500 yr ago and indicates that the transition from a pluvial early Holocene to the present-day climate conditions was p…
La Neolitización en Cantabria
2019
El territorio actual de la región de Cantabria se corresponde fundamentalmente con el sector central de la Cornisa Cantábrica, además de los valles de Campóo y Valderredible y como la práctica totalidad de trabajos de síntesis realizados tanto en el País Vasco, como en Asturias se circuscriben a sus límites regionales se ha convertido en un importante vacío de información para el estudio del proceso de neolitización en la Cornisa Cantábrica, la poca atención que se ha dispensado a los datos arqueológicos regional origina que las teorías generales sobre el proceso, o los procesos de neolitización en la Cornisa Cantábrica tengan serias lagunas. Con este breve artículo pretendemos contribuir a…
Classification of extra virgin olive oils according to their geographical origin using phenolic compound profiles obtained by capillary electrochroma…
2009
Abstract A simple and reliable method for the evaluation of the phenolic fraction of extra virgin olive oils (EVOO) by capillary electrochromatography (CEC) with UV–Vis detection, using lauryl acrylate (LA) ester-based monolithic columns, has been developed. The percentages of the porogenic solvents in the polymerization mixture, and the mobile phase composition, were optimized. The optimum monolith was obtained with a monomers/porogens ratio of 40:60% (wt/wt) using a LA/1,3-butanediol diacrylate ratio of 70:30% (wt/wt) and a 1,4-butanediol/1-propanol ratio of 25:75% (wt/wt). A satisfactory resolution between the phenolic compounds was achieved in less than 25 min with a 15:85 (v/v) ACN–wat…
