Du Néolithique récent à l'âge du Bronze dans le Centre Nord de la France : les étapes de l'évolution chrono-culturelle

2009

The collective work carried out since 2001 within the framework of a Programme Collectif de Recherche (PCR) on the Late Neolithic and the beginning of the Bronze Age in the central part of northern France leads today to a new periodisation in 8 stages for the period between 3600 and 1800 BC. Although several gaps remain, particularly for the transitions between the Middle Neolithic and the Late Neolithic on one hand and between the Late Neolithic and the Final Neolithic on the other hand, this more precise chronological frame allows to synchronize the main stages of the central part of northern France with those of the nearby regions, to propose a more dynamic vision of cultural phenomena.

Early human peopling of Sicily: Evidence from the Mesolithic skeletal remains from Grotta d'Oriente

2010

The site of Grotta d'Oriente, Island of Favignana, Sicily has yielded the complete skeleton of an adult female (OB) dated to the Mesolithic age. The cranial morphometry of this individual can provide us with some useful information about the peopling of Sicily in the Early Holocene period.Morphological affinities of OB and other Sicilian Mesolithic specimens were assessed to verify hypotheses concerning the early peopling of Sicily.Craniofacial metric data were employed in a comparative analysis with European Upper Palaeolithic (UP), Mesolithic, Neolithic, and Copper/Bronze age samples, and contemporary Italians. Both a model-free and a model-bound approach were used not only to calculate c…

Historical mining and smelting in the Vosges Mountains (France) recorded in two ombrotrophic peat bogs

2010

Two peat sequences were sampled in the vicinity of the main mining districts of the Vosges Mountains: Sainte-Marie-aux-Mines and Plancher-les-Mines. Lead isotopic compositions and excess lead fluxes were calculated for each of these radiocarbon-dated sequences. Geochemical records are in very good agreement with the mining history of the area, well known over the last millennium. Except for an anomaly corresponding to the Middle Bronze Age which has not yet been resolved, there is no clear geochemical evidence of local metal production in the Vosges before the 10th century as excess lead deposition archived between 500 BC and 500 AD is attributed to long-range transport of polluted particul…

Crystal chemical and dielectric properties of Pb0.5(5-x)LaxNb5-xFexO15system with “tetragonal tungsten bronze” structural type

2005

The lanthanum-lead and iron-niobium coupled substitution in PbNb 2 O 6 have allowed to isolate new materials of a general formula Pb 0.5(5-x) La x Nb 5-x Fe x O 15 crystallising with the tetragonal tungsten bronze structural type. The resulting influence on the lattice parameters, the ferroelectric Curie temperature and Cole - Cole plots are presented. A typical ferroelectric - paraelectric behaviour occurs in the composition range 0 ≤ x ≤ 0.33 while, a relaxor behaviour is observed in the composition range 0.33 < x < 1.

Crystal chemistry and phase transitions in mixed niobates crystallizing with tetragonal tungsten bronze structure

1990

Abstract New compounds crystallizing with tungsten bronze structure are reported. A dielectric study and X-ray analysis at various temperatures have allowed to describe some phase transitions.

Social and technological changes in the ceramic production of the Northern Levant during the LBA/IA transition: New evidence about the Sea People iss…

2019

Abstract The transition from the Late Bronze Age (LBA) to the Iron Age (IA) in the Levant is marked by the collapse of the Egyptian and Hittite empires, which dominated the political scene of the 14th–13th century BCE. The role of the Sea People, groups of migrants who were defeated by the Egyptian king Ramses III around 1175 BCE, is the focal point concerning this period. After the collapse of the LBA empires, written sources disappeared, and the archaeologists’ primary tool to define cultural processes is to analyze the evolution of pottery. Because of this, studies about the distribution of Aegeanizing ceramic production, considered here to have derived from the Sea People culture, can p…

Más allá del acero: Otros metales y sus usos en la arquitectura del siglo XXI

2009

[ES] El protagonismo que ostentan los metales como compuestos básicos para el desenvolvimiento cotidiano de la vida humana resulta evidente e irrefutable. Del mismo modo que una mayoría de las actividades diarias que realizamos serían imposibles sin el apoyo que nos brinda el metal, un amplio porcentaje de la arquitectura de la última centuria también hace descansar sus fundamentos en la solidez de una estructura metálica. Más allá del hierro como predecesor y del acero como digno sucesor, la constructiva recurre asimismo con asiduidad a otros metales para conformar con ellos la imagen final del edificio, redundando en ésta componentes tanto técnicos como expresivos de los que son responsab…
