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 …
C Preparation Protocols for Archaeological Samples at the Lmc14, Saclay, France
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 …
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…
New Chronometric Insights Into Ancient Egyptian Musical Instruments Held at the Musée Du Louvre and the Musée Des Beaux-Arts De Lyon
Very little is known about the manufacturing and use of ancient Egyptian instruments, and their discovery is very rare. An extensive radiocarbon ( 14 C) dating program has been conducted on 25 ancient Egyptian musical instruments currently held at the Louvre Museum ( musée du Louvre ) and the Lyon Museum of Fine Arts ( musée des Beaux-Arts de Lyon ). This study includes cordophones (harps, lyres, lutes), membranophones (drums, tambourines), idiop…
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…
Comparison of Two Bone-Preparation Methods for Radiocarbon Dating
In this paper, first results comparing modified Longin and ninhydrin collagen extraction methodologies are presented. The goal of this study is to investigate the bones of several species with different ages, preservation conditions, and collagen contents to determine the most suitable preparation method. Different types of samples are used such as VIRI samples, previously dated bones, and background samples. Each bone has undergone elemental ana…
Status Report on Sample Preparation Protocols Developed at the LMC14 Laboratory, Saclay, France
The main objective of this report is to present the dating process routinely applied to different types of samples at the Laboratoire de Mesure du Carbone 14 (LMC14). All the results and protocols refer to our procedures over the last 5 years. A description of the sorting and chemical pretreatments of the samples as well as the extraction and graphitization of CO 2 are reported. Our last study concerning the degradation of the blank level accordi…
Development of a Line for Dissolved Inorganic Carbon Extraction at LMC14 Artemis Laboratory in Saclay, France
We present here the new line installed at the LMC14 laboratory (Saclay, France) for dissolved inorganic carbon (DIC) extraction from marine and freshwater samples. The operating system and extraction process are described. The efficiency of the line design was checked, and the background (0.42 ± 0.11 pMC) and the reproducibility on artificial samples obtained by dissolution of IAEA-C1, IAEA-C2, and commercial bicarbonate in water were evaluated. …
Research and Development of the Artemis 14 C AMS Facility
The Artemis accelerator mass spectrometry (AMS) facility is dedicated to high-precision radiocarbon measurements. It routinely measures over 4500 samples a year for French laboratories. This paper is a status report, showing the measurements of standard, blank, and FIRI intercomparison samples. Since 2008, research and development programs have been established by the Artemis team. During the collaborations with other research laboratories, inter…
Dating French and Spanish Prehistoric Decorated Caves in Their Archaeological Contexts
The Laboratoire des Sciences du Climat et de l'Environnement (LSCE) research program on prehistoric art conducts chronological studies of parietal representations with their associated archaeological context. This multidisciplinary approach provides chronological arguments about the creation period of parietal representations. This article presents chronological investigations carried out in several decorated caves in France (La Grande Grotte, La…
