Characterization and Selection of Mortar Samples for Radiocarbon Dating in the Framework of the Modis2 Intercomparison
For several decades, many efforts have been dedicated to enhancing the accuracy of mortar radiocarbon dating and evaluating the reliability of the results concerning the typology of the examined specimens. Several assumptions that are fundamental for the application of the method may be in many cases not fulfilled, such as (a) complete primary limestone dissociation during calcination, (b) efficient separation of geogenic carbon contained in calc…
Can the 14 C Production in 1055 Ce Be Affected by Sn1054
Annually resolved radiocarbon ( 14 C) measurements on tree rings led to the discovery of abrupt variations in 14 C production attributed to large solar flares. We present new results of annual and subannual 14 C fluctuations in tree rings from a middle-latitude sequoia (California) and a high-latitude pine (Finland), analyzed for the period 1030–1080 CE, to trace a possible impact of the Crab supernova explosion, occurring during the Oort minimum…
Holocene palaeofires in Neotropics high mountains
Biomass Growth Rate of Trees from Cameroon Based on 14 C Analysis and Growth Models
The question of whether the rise in CO 2 levels observed during the industrial era has influenced the rates of tree biomass growth represents one of the main unsolved questions in the field of climate change science. In this framework, the African tropical forest represents one of the most important carbon (C) sinks, but detailed knowledge of its response to elevated CO 2 is still lacking, especially regarding tree growth rate estimations. A majo…
Radiocarbon Chronology and Paleodiet Studies on the Medieval Rural Site of Zaballa (Spain)
The archaeological site of Zaballa is a Medieval rural site located in the province of álava (Basque Country, northern Iberia). The site has been excavated during a rescue archaeology project, over an area of about 4.5 ha, where human occupation has been documented ranging from the 6th to 15th century. The archaeological operations have shown the transformation of the village, in diachronic terms, by unearthing the structure of production areas (…
Zinc Reduction as an Alternative Method for AMS Radiocarbon Dating
The pretreatment of samples for radiocarbon measurements, transforming a variety of materials into graphite solid targets, represents a critical point in the accelerator mass spectrometry (AMS) procedure. We describe the new, state-of-the-art CIRCE AMS preparation laboratory, particularly the setup and optimization of an alternative method, the zinc reduction method, for graphite target production, compared to the more common hydrogen reduction m…
