Anthropogenic lead distribution in soils under arable land and permanent grassland estimated by Pb isotopic compositions

2008

International audience; The role of land use on fate of metals in soils is poorly understood. In this work, we studied the incorporation of lead in two neighboring soils with comparable pedogenesis but under long-term different agricultural management. Distributions of anthropogenic Pb were assessed from concentrations and isotopic compositions determined on bulk horizon samples, systematical 5–10 cm increment samples, and on 24-h EDTA extracts. Minor amounts of anthropogenic lead were detected until 1-m depth under permanent grassland, linked to high earthworm activity. In arable land, exogenous Pb predominantly accumulated at depths <60 cm. Although the proximity between the two sites ens…

Noise identification and sampling frequency determination for precise Pb isotopic measurements by quadrupole-based Inductively Coupled Plasma Mass Sp…

2000

Analytical precision of the isotope ratios measured by quadrupole-based ICP-MS is drastically controlled by the low- frequency noises which originate from nebulisation and vaporisation processes, and from sample introduction systems. The unde- sirable influence of these latter can be however reduced by choosing efficiently the operating parameters. In the present study , the choice of the stabilisation time necessary in peak jump mode, and the one of the number of sweeps are discussed in the light of noise power spectra obtained with various speeds of the peristaltic pump used as sample introduction system. Obviously, the settings proposed are probably efficient only on our own ICP-MS, but …

Incomplete retention of radiation damage in zircon from Sri Lanka

2004

A suite of 18 zircon gemstones from placers in the Highland/Southwestern Complex, Sri Lanka, were subjected to a comprehensive study of their radiation damages and ages. The investigation included X-ray diffraction, Raman and PL spectroscopy, electron microprobe, PIXE and HRTEM analysis, as well as (U-Th)/He and SHRIMP U-Th-Pb age determinations. Zircon samples described in this study are virtually homogeneous. They cover the range from slightly metamict to nearly amorphous. Generally concordant U-Th-Pb ages averaging 555 ± 11 Ma were obtained. Late Ordovician zircon (U-Th)/He ages scattering around 443 ± 9 Ma correspond reasonably well with previously determined biotite Rb-Sr ages for rock…

Das Bleigewicht aus dem Hofareal der Fürstin von Vix auf dem Hochplateau des Mont Lassois.

2021

Das Bleigewicht aus dem Hofareal der Fürstin von VixDer Mont Lassois bei Vix, Dép. Côte d’Or, zählt neben der Heuneburg zu den am besten erforschten Fürstensitzen imfrühkeltischen Westhallstattkreis. 1953 wurde das späthallstattzeitliche Fürstinnengrab von Vix entdeckt. Im Rahmendes deutsch-französischen Forschungsprojektes »Keltische Fürstensitze westlich des Rheins« (1991-1997) und desfranzösischen PCR-Projektes (Projet collectif de recherche) »Vix et son environnement« (seit 2002) mit Beteiligungder Universitäten Dijon, Kiel, Wien und Zürich wurden die Altgrabungen (1930-1974) wieder aufgenommen.

Les rouelles de Moyencourt « Les Hauts du Bois de Piques » (dép. Somme / F). Nouvelles données sur l’usage de rouelles en plomb en Gaule Belgique

2018

International audience; L’ensemble de Moyencourt constitue à l’heure actuelle l’une des plus importantes séries de rouelles en plomb connue. L’examen détaillé de ces pièces a permis de définir un module principal, centré sur 7 mm, ainsi que probablement deux autres modules, respectivement de 6 mm et 8 mm de diamètre. La série, très homogène morphologiquement, est caractérisée par la rareté des rouelles individualisées et par une datation couvrant la période romaine. Le dépouillement de la bibliographie a permis de définir près de 40 points de découvertes pour ce type de matériel, 31 étant certains ; parmi eux, 19 sites ont livré un ou des chapelets de rouelles. De manière générale, les modu…

Un témoignage de gestes funéraires antiques à Bonneuil-en-France (Val-d’Oise)

2022

Eine Suchschnittprospektion bei Bonneuil-en-France (Val-d’Oise), hat eine stark holzkohlehaltige Schicht zum Vorschein gebracht, die reich an verbrannten oder durch Feuereinwirkung beeinträchtigten archäologischem Fundgut war. Dieses kann in die zweite Hälfte des 1. oder an den Beginn des 2. Jh. n. Chr. datiert werden. Die archäologische Fundstelle, die sich im Talboden am Zusammenfluss von Crould und Morée befindet, gehört zu einer seit der späten Hallstattzeit genutzten Gräberlandschaft. Mehrere Argumente sprechen dafür, dass es sich hier um eine Schüttung von Überresten einer Brandbestattung handelt, bei der durch ein Auslesen der Leichenbrandreste nur wenige menschliche Knochen erhalten…

An antique lead coffin discovered in Évreux (Eure): a multidisciplinary study

2013

The Roman cemetery of le Clos au Duc in Évreux (Eure) lasted from the 1st to the 4th c. AD. The most common funerary practice in the 1st c. AD was cremation. From the beginning of the 2nd c. AD this rapidly gave place to inhumation burials. By the end of the 3rd c. lead coffins could be found in burials, but it remained a minority practice reserved for an elite. The 2010 excavation in Évreux allowed the recovery of an example of these. It was incomplete, but the good preservation of its remains made a multidisciplinary study possible. Apart from the bones of a young woman, the lead coffin contained coins, textile, fur, calcite (CaCO3) and insects. These results make it possible to retrace t…
