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…
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 …
Tracing the 14 C bomb peak in Pierre Soulages’ artworks to improve radiocarbon dating of 20th century paintings
Flax plays an important role in art, especially for painters. Flax seeds are ground into linseed oil, which is used as binder for oil paints, and fibers are used to make linen canvas as a support for paintings. Because of the rapid growth of flax, linen canvas fiber and linseed oil are considered good candidates for the radiocarbon ( 14 C) dating of paintings. However, the time necessary to transform flax into a linen canvas must be estimated in …
Chronology of Upper Paleolithic human activities recorded in a stalagmite at Points Cave (Aiguèze, Gard, France)
In this article, we propose an approach to reconstruct the timing of human activity at Points Cave, an Upper Paleolithic rock art site located in the middle of the Ardèche River Gorge (Rhône valley, France), based on the dating and characterisation of a stalagmite containing soot. Points Cave (‘Grotte aux Points’ in French), also called the ‘little sister of Chauvet Cave’, is famous for its parietal art including a series of dots made of palm pri…

The Laboratoire de Mesure du Carbone 14 (LMC14) has operated a radiocarbon dating laboratory for almost twenty years with ARTEMIS, the Accelerator Mass Spectrometer (AMS) based on a NEC 9SDH-2 Pelletron tandem accelerator. A first status report describing the chemical pretreatment methods was published in 2017 (Dumoulin et al. 2017). This article summarizes updates of the routine procedures and presents new protocols. The quality checks in place …
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…
First cross dating (U/Th-14C) of calcite covering rock paintings in Africa
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…
Identification in Pore Waters of Recycled Sediment Organic Matter Using the Dual Isotopic Composition of Carbon ( Δ 13 C and Δ 14 C)
Estuaries and deltas are crucial zones to better understand the interactions between continents and oceans, and to characterize the mineralization and burial of different sources of organic matter (OM) and their effect on the carbon cycle. In the present study, we focus on the continental shelf of the northwest Mediterranean Sea near the Rhône river delta. Sediment cores were collected and pore waters were sampled at different depths at one stati…
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…
First experimental reconstruction of an Angkorian iron furnace (13th–14th centuries CE)
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…

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…
Holocene Hydroclimate Variability in Central Scandinavia Inferred from Flood Layers in Contourite Drift Deposits in Lake Storsjön
Despite the societal importance of extreme hydroclimate events, few palaeoenvironmental studies of Scandinavian lake sediments have investigated flood occurrences. Here we present a flood history based on lithological, geochemical and mineral magnetic records of a Holocene sediment sequence collected from contourite drift deposits in Lake Storsjön (63.12° N, 14.37° E). After the last deglaciation, the lake began to form around 9800 cal yr BP, but…
Isotopic Signature (δ 13 C, ∆ 14 C) of DIC in Sediment Pore Waters
A better understanding of the dynamics of different particulate organic matter (OM) pools in the coastal carbon budget is a key issue for quantifying the role of the coastal ocean in the global carbon cycle. To elucidate the benthic component of this carbon cycle at the land-sea interface, we investigated the carbon isotope signatures (δ 13 C and ∆ 14 C) in the sediment pore waters dissolved inorganic carbon (DIC) in addition to the sediment OM t…
New pollen evidence from Nariani (Georgia) for delayed postglacial forest expansion in the South Caucasus
The nature and timing of environmental changes throughout the last glacial-interglacial transition in the South Caucasus, and more widely in eastern Europe, are still not fully understood. According to certain pollen records, forest expansion occurred in many areas several millennia after what is considered worldwide as the onset of the Holocene. The current problem we face is that the time lag in forest expansion varies from one sequence to anot…

Dating the Lascaux Cave Gour Formation
Lascaux Cave is renowned for its outstanding prehistoric paintings, strikingly well-preserved over about 18,000 yr. While stalagmites and stalactites are almost absent in the cave, there is an extensive calcite flowstone that covered a large part of the cave until its opening for tourists during the 1950s. The deposit comprises a succession of calcite rims, or “gours,” which allowed seepage water to pond in large areas in the cave. Their possible…
