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…
Radiocarbon dating of lime plaster from a Roman period cistern in ancient Gerasa, Jerash in Jordan
Ancient Gerasa (Jerash, since the Islamic period) is a city with a rich archaeological heritage from prehistory onwards, with the periods from Roman times into the Early Islamic period best attested. A Danish-German team has been working in the Northwest Quarter of the city since 2011. Among the findings was a Roman period monumental cistern that was intentionally filled in, at one point in time. The complexity of the archaeology raised chronolog…
Revisiting radiocarbon dating of lime mortar and lime plaster from Jerash in Jordan
Ancient Gerasa (its Greco-Roman name)/Islamic Jerash (its later Arab name) is one of the most well-known pre-modern urban sites in northern Jordan, which flourished throughout antiquity and into the early Islamic period. Direct dating of mortar and plaster in Jerash is challenging due to the area’s abundance of geological carbonates that hamper the use of radiocarbon mortar methodologies as shown by previous attempts. Therefore, this study revisi…
Ramped pyroxidation
Comparison of Thermal Decomposition and Sequential Dissolution—two Sample Preparation Methods for Radiocarbon Dating of Lime Mortars
Dating lime mortar samples using the radiocarbon ( 14 C) method can be difficult. This is because the contamination is similar to the primary dating material (CaCO 3 ) and consequently difficult to remove. Mortar can also have late-in-formation pyrogenic carbonate from interactions with the environment after the initial hardening phase, such as recrystallization, fire damage or delayed hardening. When 14 C dating a system of primary dating materi…
A field guide to mortar sampling for radiocarbon dating
Radiocarbon dating of mortars is a method for absolute dating of historical mortared stone structures. Successful mortar dating studies have answered chronological questions, while other studies have revealed that mortar samples can have complications and contaminants. These can cause inconclusive results even with present state‐of‐the‐art techniques. Previous research shows that adequate and proper sampling of mortar samples is of fundamental im…
Delayed Hardening and Reactivation of Binder Calcite, Common Problems in Radiocarbon Dating of Lime Mortars
When sampling mortars for radiocarbon ( 14 C) dating it is crucial to ensure that the sample has hardened rapidly relative the resolution of the dating method. Soft and porous lime mortars usually fulfill this criterion if the samples are taken from an uncovered surface from less than a few centimeters deep. However, hard, concrete-like mortars may be impermeable for carbon dioxide and even the outermost centimeters may still contain uncarbonated…
Integrated Dating of the Construction and Restoration of the Modena Cathedral Vaults (Northern Italy)
After the last damaging earthquake in 2012, an anti-seismic reinforcement project of the cathedral of Modena was designed giving us the opportunity to investigate and date the building materials. Radiocarbon ( 14 C), optically stimulated luminescence (OSL), and thermoluminescence (TL) dating techniques were performed on the vaults with the aim to (1) clarify the construction timing, (2) define the history of the restorations, and (3) explore the …
Preparation and Dating of Mortar Samples—Mortar Dating Inter-Comparison Study (Modis)
Seven radiocarbon laboratories: Åbo/Aarhus, CIRCE, CIRCe, ETHZ, Poznań, RICH, and Milano-Bicocca performed separation of carbonaceous fractions suitable for 14 C dating of four mortar samples selected for the MOrtar Dating Inter-comparison Study (MODIS). In addition, optically stimulated luminescence (OSL) analyses were completed by Milano-Bicocca and IRAMAT-CRP2A Bordeaux. Each laboratory performed separation according to laboratory protocol. Re…
AMS 14C dating at Can Ferrerons, a Roman octagonal building in Premià de Mar, Barcelona
A singular Roman dwelling, octagonal in ground-plan, was excavated in the year 2000, in Premià de Mar. It is a freestanding pavilion within a larger settlement called Gran Via-Can Ferrerons. It was not possible to date it archaeologically because the basement trenches did not contain any significant dating artefacts. Archaeological research undertaken into the architectural typology of the monument led us to the hypothesis that the structure is t…
Radiocarbon analysis of mortar from Roman and Byzantine water management installations in the Northwest Quarter of Jerash, Jordan
Jerash (Gerasa) in northwestern Jordan is an important Decapolis city displaying urban development for more than a millennium beginning in the late Hellenistic period (1st century CE). Despite more than a hundred years of archaeological explorations at the site there are still major questions about the city's urban development which are left open due to the nature of the archaeological investigations undertaken at the site. This in particular per…
Radiocarbon Dating of Dutch Mortars Made from Burned Shells
AMS-bascd radiocarbon dating was applied to Medieval lime mortars made from burned shells and aggregate including both shore sediments and neovolcanic rocks. Three mortar samples from the city of Leiden near Amsterdam were prepared using the same kind of acid hydrolysis technique as has been earlier used for dating mortars made from burned marble and limestone. Five consecutive CO 2 fractions were collected from each sample to form age profiles a…
C Dating of Fire-Damaged Mortars from Medieval Finland
This study focuses on radiocarbon dating of mortars that have withstood city fires and display visible fire damage effects. Some fire-damaged and undamaged original Medieval mortars from the same site have also been tested. The mortars were heated at different temperatures and then analyzed using the same preparation procedures as in 14 C dating of mortars to see what kind of changes the heating would introduce to the mineralogy, chemistry, and t…
Dispelling the Chimera of 'Self-Contained Regimes' International Law and the WTO
International lawyers have in recent years expressed much unease about the perceived fragmentation of their legal system. In truth, however, international law has always been fragmented without losing its ability to operate. A threat, rather, arises from the ongoing proliferation of special regimes endowed with strong institutional frameworks and an ability to set new international norms. This expansion begs an uncomfortable question: What if suc…
