Tracing the origin of organic matter in river deltas using the dual isotopic composition of carbon (δ 13 C and Δ 14 C): A decade of study in sediments and porewaters of the Rhône River delta
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…
Secular variation of the geomagnetic field in Sub-Saharan Africa over the last millennia: New archaeomagnetic data from West Africa and Ethiopia
Instrumental observations highlight that intertropical Africa is one of the areas with the most rapid changes in the modern geomagnetic field. The secular variation beyond the last centuries is poorly known due to lack of data, this large region representing only 0.7% of the GEOMAGIA50 database. The resulting large uncertainties in global geomagnetic models in this area make in particular the history of the present South Atlantic anomaly unclear.…
A versatile integrated protocol to extract organic balms from archaeological linen: A new way to provide reliable radiocarbon dating for contaminated textile
A typical postwar workshop: Insights into Simon Hantaï’s oil paint palette
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: Historical Mortars. Participation in the Modis International Intercomparison Campaign
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…

Radiocarbon Dating of Urban Secondary Carbonate Deposits: Site Effect and Implication for Chronology: Case Study of Paris and Versailles Palace Fountains
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: A First Estimation From Museum Specimens
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…

Calcium Oxalate Radiocarbon Dating: Preliminary Tests to Date Rock Art of the Decorated Open-Air Caves, Erongo Mountains, Namibia
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…

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…

Iron Bar Trade between the Mediterranean and Gaul in the Roman Period: 14 C Dating of Products from Shipwrecks Discovered off the Coast of Saintes-Maries-de-la-Mer (Bouches-du-Rhône, France)
The large number of iron-laden wrecked ships discovered off Saintes-Maries-de-la-Mer (south of France) since the 1990s has enriched our knowledge of both maritime trade in the Mediterranean and the ferrous bars used during antiquity. This exceptional corpus has spawned numerous studies in the fields of archaeology, history, and archaeometallurgy, but, despite a relatively well-documented context, the chronology of wrecks is still to be clarified.…
A high-precision chronological model for the decorated Upper Paleolithic cave of Chauvet-Pont d’Arc, Ardèche, France
Significance We compiled a set of more than 250 radiocarbon dates related to the rock art, human activities, and bone remains in the Chauvet-Pont d'Arc Cave (Ardèche, France) and derive a modeled absolute chronology of the human and cave bear occupations of this site, presented here in calendar years. It provides an insightful framework for the successive events that occurred in the cave during the Paleolithic period.

Embalming as a Source of Contamination for Radiocarbon dating of Egyptian Mummies: On a New Chemical Protocol to Extract Bitumen
Radiocarbon dating of Egyptian mummies could be challenged by embalming materials, especially bitumen which is attested in textual sources as being used during the Late Period. Six Egyptian mummies held at the Musée des Confluences in Lyon (France) have been radiocarbon dated, among which two embalmed mummies have given results older than expected, both on textile and organic material (flesh/skin). Radiocarbon dates’ ageing relates to the use of …
