Full‐Vector Archaeomagnetic Dating of a Medieval Limekiln at Pinilla Del Valle Site (Madrid,Spain)

Archaeomagnetic dating based on the full geomagnetic field vector was carried out on a limekiln excavated at Pinilla del Valle archaeological site (Madrid, Spain). The limekiln tradition in this area is largely documented by historical sources for recent centuries but the date of the studied kiln's last use was unknown. The combination of mean archaeomagnetic directional and absolute archaeointensity results shows that the kiln was last used between ad 1296 and 1413, in good agreement with two independent radiocarbon dates. This study provides the first archaeomagnetic evidence that the local limekiln tradition dates back to at least late medieval times. Furthermore, the inclusion of these data in the Iberian secular variation curve and geomagnetic field models will help to improve the archaeomagnetic dating technique.     

Compositional Analyses of Mortars from the Late Antique Site of Son Peretó (Mallorca,Balearic Islands,Spain): Archaeological Implications

The paper presents the mineralogical, petrographic and chemical analyses of mortars from an Early Christian complex found in Mallorca (Balearic Islands) and dated to between the fifth and the eighth centuries ad . We characterized several mortars found at the site, in order to gather information on the raw materials used, as well as on the technology of production, and similarities among the samples. The analyses were aimed at solving specific archaeological questions regarding the building phases of the site and, in particular, the synchronic or diachronic presence of two baptismal basins in the same Christian complex.     

Technological Choices in Hand‐Made Indigenous Pottery from Western Mallorca (Balearic Islands,Spain) (C.1200–75 bc): An Archaeometric Approach

This paper addresses the technological choices observed in Mallorca (Spain) for the production of hand‐made pottery during the Late Bronze and Iron Age. We have conducted a diachronic analysis of the ceramic assemblages recovered from two archaeological sites placed in the same territory by means of X‐ray fluorescence and optical microscopy by thin‐section analysis. The archaeometric characterization of the hand‐made vessels allows us to establish several compositional groups related to the use of different raw materials and certain paste recipes associated with the archaeological sites and periods considered. Thus, this study evidences different productive strategies in each site and across time in the same geographical area.     

Flint and Quartzite: Distinguishing Raw Material Through Bone Cut Marks

Since the 1980s, several experimental analyses have been able to differentiate some lithic tool types and some of their raw materials according to the morphology of cut marks imprinted by such tools when used for butchering activities. Thus, metal tool use has been differentiated in contexts with an abundance of lithic tools, or even the use of hand axes has been documented in carcass processing, in contrast with simple unretouched or retouched flakes. As important as this information is, there are still other important aspects to be analysed. Can cut marks produced with different lithic raw material types be differentiated? Can cut marks made with different types of the same raw material type be characterized and differentiated? The objective of this study is to evaluate if cut marks resulting from the use of different flints and different quartzites are distinguishable from each other. In the present work, an experimental analysis of hundreds of cut marks produced by five types of flint and five varieties of quartzite was carried out. Microphotogrammetry and geometric–morphometric techniques were applied to analyse these cut marks. The results show that flint cut marks and quartzite cut marks can be characterized at the assemblage level. Different types of flint produced cut marks that were not significantly different from each other. Cut marks made with Olduvai Gorge quartzite were significantly different from those produced with a set comprising several other types of quartzites. Crystal size, which is larger in Olduvai Gorge quartzites (0.5 mm) than Spanish quartzites (177–250 μm), is discussed as being the main reason for these statistically significant differences. This documented intra‐sample and inter‐sample variance does not hinder the resolution of the approach to differentiate between these two generic raw material types and opens the door for the application of this method in archaeological contexts.     

Ceramic Ethnoarchaeometry in Western Sardinia: Production of Cooking Ware at Pabillonis

Ceramic ethnoarchaeology has been used to explore fully the chaîne opératoire and to understand all of the stages and factors involved in pottery production, such as raw material selection or paste recipes used by the potters. This work presents the results of the application of compositional analysis undertaken in the village of Pabillonis (western Sardinia, Italy), the main cooking ware production centre of the island. Pottery and local clays have been characterized using a combination of analytical techniques. By integrating the ethnographic information and the archaeometric approach, it was possible to reconstruct the operational sequence, exploring the relationship between the processing of raw materials and the functionality of the final products, and the intra‐production compositional variability.
