The Worldwide Marine Radiocarbon Reservoir Effect: Definitions, Mechanisms, and Prospects
Sign Up to like & getrecommendations! Published in 2018 at "Reviews of Geophysics"
DOI: 10.1002/2017rg000588
Abstract: When a carbon reservoir has a lower radiocarbon content than the atmosphere, this is referred to as a reservoir effect. This is expressed as an offset between the radiocarbon ages of samples from the two… read more here.

Palaeoecological background of the Upper Palaeolithic site of Ságvár, Hungary: radiocarbon‐dated malacological and sedimentological studies on the Late Pleistocene environment
Sign Up to like & getrecommendations! Published in 2021 at "Journal of Quaternary Science"
DOI: 10.1002/jqs.3306
Abstract: In this paper, the authors present new palaeoecological and sedimentological results from the Upper Palaeolithic site of Ságvár, Hungary. Simple (abundance and dominance) and advanced (cluster analysis, principal component analysis, correspondence) statistical analyses of malacological… read more here.

DOI: 10.1007/s12520-020-01077-3
Abstract: A conserved painting removed from a Neolithic collective grave in Marne, France, provided an opportunity for radiocarbon dating to place Les Ronces Hypogeum 21 (Villevenard) into the chronology of that region. Chemical analysis with direct… read more here.

DOI: 10.1016/j.culher.2021.05.003
Abstract: Abstract Preservatives and consolidants make it difficult or impossible to obtain accurate radiocarbon dates on many organic artefacts from museums or archaeological collections. Discovered in an Irish bog in the 1960s, the Cuillard Bowl is… read more here.

Reassessment of the C-13/C-12 and C-14/C-12 isotopic fractionation ratio and its impact on high-precision radiocarbon dating
Sign Up to like & getrecommendations! Published in 2017 at "Geochimica et Cosmochimica Acta"
DOI: 10.1016/j.gca.2017.05.038
Abstract: Abstract The vast majority of radiocarbon measurement results (14C/12C isotopic ratios or sample activities) are corrected for isotopic fractionation processes (measured as 13C/12C isotopic ratios) that occur in nature, in sample preparation and measurement. In… read more here.
