Radiocarbon dating of mortars from monastery hill in Tyniec, Poland
The Benedictine Abbey in Tyniec is the oldest existing monastery in Poland (11th cent. AD). The historic walls of the Monastery have survived to this day and crown the limestone hill on the Vistula River. The geological structure of the surrounding area is reflected in the composition of the mortars. In vicinity of Tyniec one may observe outcrops of Upper Jurassic limestones represented by two facies: bedded limestones with cherts and massive lim…
Fading of the 14 C bomb peak – students’ project to observe the Suess effect
The natural variability of atmospheric 14 C has been significantly altered by anthropogenic activities linked to technological advancements and energy consumption over the past two and a half centuries. The Suess effect, a consequence of the combustion of old carbon (fossil fuels) since the mid-18th century and the bomb peak from the mid-20th century’s thermonuclear tests, has obscured the natural 14 C signal in the atmosphere. This study present…
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…
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…
Radiocarbon Dating of Mortars and Charcoals from Novae Bath Complex
Carbonaceous mortars from Novae (Bulgaria) contain local loess, crushed bricks and ceramic dust (pozzolanic materials). The reaction between lime and pozzolanic additives occurs easily and affects the rate and course of leaching reaction of carbonates in orthophosphoric acid during the sample pretreatment for dating. The composition of the Bulgarian mortars does not allow for unambiguous conclusions about chronology, but together with the observa…
Radiation Defects in Lime Mortars and Plasters Studied by EPR Spectroscopy
Electron paramagnetic resonance (EPR) spectroscopy is a well-established method of dating based on trapped charges, applied to various crystalline materials, including carbonates, bones, and teeth. It provides a detailed insight into the structure of radiation defects—paramagnetic centers generated by irradiation, without the need of a painstaking sample preparation, often challenging in other methods. Using EPR we studied the effect of γ radiati…
Modeled and Measured Carbon Isotopic Composition and Petrographically Estimated Binder-Aggregate Ratio—Recipe for Binding Material Dating
This paper presents the results of radiocarbon ( 14 C) dating of bulk mortars and reports an attempt of implementation of the knowledge about the isotopic fractionation, based on δ 13 C measurements, to make the age correction for mortars, together with verification of such correction based on the percentage estimation of carbonate components, namely binder and aggregate. To evaluate the variability of isotopic fractionation during CO 2 absorptio…
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…
Methodological Aspect of Mortars Dating (Poznań, Poland, Modis)
An accurate radiocarbon ( 14 C) dating of mortars requires adjusting the sample preparation procedure to each specific mortar composition. In order to follow the influence of mortar components and the preparation procedure on dating results, a mortar intercomparison study (MODIS) was undertaken by 10 organizations (institutes and laboratories) in the analyses of four different types of mortars (see in this issue Hajdas et al. 2017 and Hayen et al…
Analysis of Charcoal and Wood from Czarnowko Site (Pomerania Region, Poland)
This article presents the results of interdisciplinary analysis of samples from the Czarnówko archaeological site in northern Poland, reporting the first radiocarbon dates for the site in comparison with its relative chronology. The site is of high importance because of its scale and opulence of artifacts. It was used for over 900 yr, from the 7th century BC up to the 3rd century AD, by populations of different cultures (the Lusatian, Pomeranian,…
