Ramped pyrolysis radiocarbon dating
Radiocarbon dating of mortar has long been an intriguing yet challenging field of research. The key issue involves distinguishing archaeologically meaningful carbon, which reflects the original setting of the mortar, from various types of contaminant carbon. Recent applications of the ramped pyrolysis method, which allows for the separation of carbonates based on their thermal decomposition behaviour, have shown significant potential to overcome …
C offsets in marine limpets
The suitability of marine limpet shells for radiocarbon dating may depend on potential offsets due to diet and habitat, especially with regard to grazing mollusks on carbonate substrates (Dye 1994; England et al. 2013). A previous study on one grazing limpet species on the coast of Ireland found no offsets from carbonate substrates (Allen et al. 2019), but a similar study from mediterranean coasts found significant offsets on carbonate substrates…
Radiocarbon mortar dating of newly uncovered medieval ceiling paintings at Stavanger Cathedral, Norway
Dating of newly discovered medieval wall paintings using ramped pyrolysis radiocarbon dating of mortar with ATR-FTIR screening. One of only 3 ceiling painting examples in Norway and the first to be discovered in 50 years. • First in-depth scientific dating of Norwegian wall paintings and Stavanger Cathedral. • 13th century AD age estimate that challenges traditional interpretations. • Successful application of mortar dating to building chronology…
Ramped pyrolysis radiocarbon dating of lime lumps
Ramped pyrolysis radiocarbon dating was carried out on lime lumps from what was believed to be the oldest remains of Turku Cathedral, Finland, the first sacristy. Lumps extracted from bulk mortar from five sampling locations were analysed. For each sample, 5–6 fractions of CO2 from different temperature fractions were radiocarbon dated. One of the five samples exhibited significant contamination for its lowest temperature fractions. For the remai…
A New Ramped Pyroxidation/Combustion Facility at 14 Chrono, Belfast
The Belfast Ramped Pyroxidation/Combustion (RPO/RC) facility was established at the 14 CHRONO Centre (Queen’s University Belfast). The facility was created to provide targeted analysis of bulk material for refined chronological analysis and carbon source attribution for a range of sample types. Here we report initial RPO results, principally on background material, but also including secondary standards that are routinely analyzed at 14 CHRONO. A…
An Investigation into 14 C offsets in Modern Mollusk Shell and Flesh from Irish Coasts shows no Significant differences in areas of Carbonate Geology
Our ability to reliably use radiocarbon ( 14 C) dates of mollusk shells to estimate calendar ages may depend on the feeding preference and habitat of a particular species and the geology of the region. Gastropods that feed by scraping are prone to incorporation of carbon from the substrate into their shells as evidenced by studies comparing the radiocarbon dates of shells and flesh from different species on different substrates (Dye 1994; Hogg et…
