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…
Mortar Dating Methodology
Absolute dating of mortars is crucial when trying to pin down construction phases of archaeological sites and historic stone buildings to a certain point in time or to confirm, but possibly also challenge, existing chronologies. To evaluate various sample preparation methods for radiocarbon ( 14 C) dating of mortars as well as to compare different dating methods, i.e. 14 C and optically stimulated luminescence (OSL), a mortar dating intercomparis…
Radiocarbon Determination of Past Growth Rates of Living Acacia Tortilis Trees from Two Arid Sites in the Eastern Sahara
Reconstructions arc presented of past growth rates of 10 Acacia tortilis trees, 5 growing at an arid site (Gebeit, Sudan) and 5 at a hyperarid site (Wadi Nuqrus, Egypt). The reconstructions were made using a free-shape age-depth model based on a series of 14 C dates obtained on samples taken along the wood cores retrieved from the trunks of the trees (78 dates in total). In spite of the large difference in annual precipitation between the 2 sites…

C Dating of Carbonate Mortars from Polish and Israeli Sites
The presented research involves the analysis and radiocarbon dating of 2 different groups of carbonate mortars, from Kraków, Poland and Hippos, Israel. Differences in composition of the mortars are reflected in different rates of their acid leaching. The Israeli mortars contain carbonate-basaltic aggregates, which may cause overestimation of 14 C age. Preliminary processing of these samples (choice of selected grain-size fraction and collection o…
Foraminiferous Limestone in 14 C Dating of Mortar
Mortar as a mixture of binder and aggregate can be reliably dated with radiocarbon if the applied preparation method allows one to eliminate unburnt carbonate fragments, bearing 14 C-depleted carbon and causing overestimation of 14 C age. To avoid these problems, separation of specific grain-size fractions of mortar and 14 C analysis of the CO 2 portions collected in different time intervals of the acid-leaching reaction is usually helpful. In th…
AMS 14 C Dating of Romanesque Rotunda and Stone Buildings of a Medieval Monastery in Łekno, Poland
Archaeological excavations performed for many years in Łekno, central Poland, have exposed relicts of wooden fortified settlements, and in its enclosure also basements of stone buildings, consisting of Romanesque rotunda and a Cistercian monastery, including an oratory, church, and abbot's house. Earlier archaeological, structural, and stratigraphical studies have shown that these buildings were constructed in a sequence and represented several p…
Radiocarbon Chronology of the Ancient Settlement in the Golan Heights Area, Israel
Carbonate binders from mortars and plasters as well as charcoal fragments sampled at the ancient settlement of Hippos (Sussita) have been subjected to radiocarbon dating by gas proportional counting (GPC) and accelerator mass spectrometry (AMS). Hippos is situated on the east coast of the Sea of Galilee (32°46′N, 35°39′E) at the top of a hill in the Golan Heights area, Israel. According to historical-archaeological data, the town had functioned s…
Radiocarbon Dating of Modern Peat Profiles
We present studies of 9 modern (up to 400-yr-old) peat sections from Slovenia, Switzerland, Austria, Italy, and Finland. Precise radiocarbon dating of modern samples is possible due to the large bomb peak of atmospheric 14 C concentration in 1963 and the following rapid decline in the 14 C level. All the analyzed 14 C profiles appeared concordant with the shape of the bomb peak of atmospheric 14 C concentration, integrated over some time interval…

Preparation of Graphite Targets in the Gliwice Radiocarbon Laboratory for AMS 14 C Dating
A line for preparation of graphite targets for accelerator mass spectrometry (AMS) radiocarbon dating has been built in the Gliwice 14 C Laboratory. The AMS 14 C measurements of our targets are performed in the Leibniz-Labor für Altersbestimmung, Kiel, Germany. The quality of our line has been tested in two series of AMS 14 C measurements of background and Ox-II standard samples and by measurements of the amount of CO 2 released during combustion…
