Tracing the origin of organic matter in river deltas using the dual isotopic composition of carbon (δ 13 C and Δ 14 C)
River deltas play a crucial role in the global carbon cycle, acting both as significant carbon sinks and as sources of CO2 to the atmosphere. The Rhône River delta is a key site for studying these processes due to its high sedimentation rates and its unique radiocarbon signatures influenced by anthropogenic activities. This study compiles over 10 years of research to assess the sources and fate of organic matter (OM) in the Rhône River delta, usi…
C Dating of Lead White in Painted Decorations
Radiocarbon dating of lead white has progressed considerably in the last decade. Today, the protocol enables the analysis of various types of samples: pure lead white in cosmetics, ancient and modern paint layers containing lead white and oil, and mixtures of lead white and calcite. However, it has also been shown that the presence of a large amount of calcite in lead white paint can alter the radiocarbon result through contamination with dead ca…
U/Th Dating of Secondary Carbonate Deposits in Underground Galleries of Fourvière Hill (Lyon, France) Reveals a Water Supply System in Operation From the Roman Period to the Middle Ages
The recent discovery of a water draining structure known as the Antiquaille galleries in Fourvière hill, in the center of Lyon, France (ancient Lugdunum), sheds light on the water drainage system built by the former inhabitants of this area for their water needs. We studied secondary carbonate deposits found in two galleries of this system: a massive flowstone and thin white layers of CaCO 3 found interbedded in a collapsed gallery. The study of …
Medieval polychromy from Parisian Gothic sculptures (1145–1250)
A typical postwar workshop
Simon Hantaï (1922–2008) was a highly influential postwar painter in Paris whose innovative serial practice, creative curiosity and theoretical convictions inspired a number of his contemporaries. His art media are typical of the period, consisting of commercial artists’ products, sold in tubes and cans, which were available to artists in Europe and beyond. We have studied a series of samples from the brands Lefebvre-Foinet, Lefranc & Bourgeois a…
Development of a 14 C Protocol at the Lmc14 for the Dating of Cultural Heritage Materials
The absolute dating of mortar by accelerator mass spectrometry (AMS) has been the subject of renewed interest for several years. International intercomparison campaigns, called MODIS (MOrtar Dating Intercomparison Study), have been carried out. The first MODIS-1 campaign highlighted limitations in mortar dating, due to the similarity between the primary material to be dated (binder) and the contaminant (exogenous CaCO 3 ). Methods have since emer…
Years of Ams 14 C Dating Using the Artemis Facility at the Lmc14 National Laboratory
In 2001, five French public organizations (CNRS, CEA, IRD, IRSN, and the Ministère de la Culture) signed an agreement to purchase a new accelerator mass spectrometer to provide radiocarbon dating services at the national level. The Laboratoire de Mesure du Carbone 14 (LMC14) was set up in Saclay (France) around ARTEMIS, an AMS system based on a 3MV Pelletron from NEC and installed in early 2003. In 2015, the LMC14 joined the Laboratoire des Scien…
Radiocarbon Dating of Urban Secondary Carbonate Deposits
In urban environments, diachronic evolution of water quality can be reconstructed using geochemical analysis of urban secondary carbonate deposits (USCDs), from urban underground structures, similar to speleothems from natural caves. The use of the radiocarbon bomb peak to build their precise chronology was recently tested in two Paris-area urban sites (France). In this study, new samples from contrasted environments in the Paris region were samp…
Marine Reservoir Effect of Spermaceti, a Wax Obtained From the Head of the Sperm Whale
Spermaceti is a waxy substance found in the head cavities of sperm whales ( Physeter macrocephalus and P. catodon ). This substance had a variety of commercial applications from the end of the 18th to the beginning of the 20th century, such as candles, soap, cosmetics and other compounds. Spermaceti was also occasionally used as wax for modeling sculptures. In order to date such artworks the marine reservoir effect (MRE) has to be considered. The…

La datation des cuirs dorés
Dans le domaine des arts décoratifs, l’utilisation de cuir doré, le plus souvent peint, semble apparaître dans les royaumes ibériques à la fin du Ier millénaire après J.-C., peu après la conquête arabe. Ces cuirs dorés connurent leur apogée dans la péninsule espagnole au xvie siècle. Ils étaient souvent employés pour confectionner des tentures murales et des images pieuses. Comparativement à leur importante production, peu de ces décors sont parv…
Calcium Oxalate Radiocarbon Dating
The direct dating of rock paintings is not always possible due to the lack of organic carbon compounds in pigments, or because sampling from a heritage site is often restricted. To overcome these limitations, dating laboratories have to develop new approaches. In this study, we consider sampling calcium oxalate crusts covering the painted artworks as a way to indirectly date the rock art. This stratigraphic approach includes isolating and extract…
Artemis, the 14 C Ams Facility of the Lmc14 National Laboratory
Quality control procedures have been developed at the Laboratoire de Mesure du Carbone 14 (LMC14) national laboratory throughout the years of operation. Routine procedures are applied to sample preparation depending on their composition and their size. The tuning of the ARTEMIS AMS facility, hosted by the LMC14 laboratory, uses an accurate procedure. A batch of unknown samples is measured with accompanying samples (primary and secondary standards…
Thermal Decomposition of Lead White for Radiocarbon Dating of Paintings
Lead carbonates were used as cosmetic and pigment since Antiquity. The pigment, known as lead white, was generally composed of cerussite and hydrocerussite. Unlike most ancient pigments, lead white was obtained by a synthetic route involving metallic lead, vinegar and organic matter. Fermentation of organic matter produces heat and CO 2 emission, leading to the formation of carbonates. As lead white is formed by trapping CO 2 , radiocarbon ( 14 C…
