Lead isotope analysis of lead-tin-glaze via on-site portable laser ablation sampling of 17-18th century Delftware (earthenware)
This study investigates the application of portable laser ablation sampling followed by multi-collector inductively coupled plasma mass spectrometry to determine lead isotope ratios (LIR) of thirteen 17–18th century Delftware earthenware objects. A method was developed to minimize invasiveness while obtaining sufficient material for accurate isotopic analysis. The method is applicable to all Pb-rich glazes. The white glaze of individual Delftware…
For there is no rock
This paper presents the first systematic study of pre-Columbian imported stone celts recovered from the limestone islands of the Lucayan archipelago, comprising The Bahamas and the Turks and Caicos Islands of the northern Caribbean/West Atlantic. The majority derive from antiquarian collections and early archaeological investigations, prior to the destruction of many sites due to guano mining and development; only a handful have been recovered du…
A holistic provenance and microwear study of pre-colonial jade objects from the Virgin Islands
Pre-colonial Caribbean jade objects from the National Museum of Denmark Hatt Collection were subjected to a provenance and microwear analysis. Thirty-nine jade celts and bodily ornaments from the US Virgin Islands, i.e., St. Croix, St. Thomas, St. John, and five celts from the West Indies of unknown location, St. Vincent, Cuba and the Dominican Republic were analysed. A comprehensive in-depth examination of jade adornments from St. Croix, combini…
Analysis of the CHARM Cu‐alloy reference materials using excimer ns‐LA‐ICP‐MS
Excimer nano‐second laser ablation inductively coupled plasma mass spectrometry (ns‐LA‐ICP‐MS) is an important tool in chemical characterization of Cu alloys. However, variable matrix‐induced elemental fractionation in Cu alloys poses a significant challenge. We systematically investigate this issue by analysing the Cultural Heritage Alloy Reference Material Set (CHARM) of Cu alloy targets. The extent to which silicate glass reference materials c…
Identification of a female murder victim found in Burgenland, Austria in 1993
In 1993, the skeletal remains of a female corpse were found in Burgenland, Austria. Initial identification of the approximately 25-35-year-old female appeared impossible, but the case was reopened 23 years later. By applying biogeochemical isotope methods to her body tissues, the geographical origin of the unknown corpse could be predicted. The results of the C, N, S, H, Sr, and Pb isotope analyses suggested that the female did not originate from…
Trace-elemental and multi-isotopic (Sr-Nd-Pb) discrimination of jade in the circum-Caribbean
Dense and strong, hydrothermal-metasomatic jadeitite and jadeite-omphacite rocks were used as tools and adornments throughout the wider Caribbean since initial inhabitation. Regionally, rich sources of jadeitite and jadeite-omphacite jade are known only in Guatemala (north and south of the Motagua Fault Zone), eastern Cuba and the northern Dominican Republic, establishing that humans transported jadeitic material over vast distances. This study v…
A dietary assessment of colonial Cape Town's enslaved population
There is a growing body of bioarchaeological research on eighteenth and nineteenth century colonial Cape Town, a significant node in the transportation networks of both the Indian and Atlantic oceanic slave trades, attempting to shed light on the lives of enslaved persons. Here, a preliminary archaeological isotopic dietary baseline for the colonial Cape is presented. It is apparent from the data that cattle tended to graze far inland from Cape T…
Micro‐invasive method for studying lead isotopes in paintings
A micro‐invasive technique is presented that enables pigment sampling from individual layers of a painting cross‐section by obtaining a furrow 10–50 μm wide of chosen length. Combined with increased sensitivity of lead (Pb) isotope analysis using multicollector inductively coupled plasma mass spectrometry (MC‐ICPMS) equipped with a 10 13 Ω resistor or a Pb double‐spike technique, the amount of Pb needed for isotopic analysis is drastically reduce…
Strontium, oxygen, and carbon isotope variation in modern human dental enamel
OBJECTIVES: Isotopic analyses using human dental enamel provide information on the mobility and diet of individuals in forensic and archeological studies. Thus far, no study has systematically examined intraindividual coupled strontium (Sr), oxygen (O), and carbon (C) isotope variation in human enamel or the effect that caries have on the isotopic integrity of the enamel. The inadequate quantification of isotopic variation affects interpretations…
Lapidary production in the eastern Caribbean
The present paper examines bodily ornaments made of semiprecious lithic materials from the site of Pearls on the island of Grenada. The site was an important node in long-distance interaction networks at play between circum-Caribbean communities during the first centuries of the Common Era. Pearls was an amethyst bead-making workshop and a gateway to South America, from where certain lapidary raw materials likely originated. The importance of the…
Diverse and Dynamic Dietary Patterns in Early Colonial Cuba
The European conquest and colonization of the Caribbean precipitated massive changes in indigenous cultures and societies of the region. One of the earliest changes was the introduction of new plant and animal foods and culinary traditions. This study presents the first archaeological reconstruction of indigenous diets and foodways in the Caribbean spanning the historical divide of 1492. We use multiple isotope datasets to reconstruct these diets…

A bioavailable strontium isoscape for Western Europe
Strontium isotope ratios (87Sr/86Sr) are gaining considerable interest as a geolocation tool and are now widely applied in archaeology, ecology, and forensic research. However, their application for provenance requires the development of baseline models predicting surficial 87Sr/86Sr variations ("isoscapes"). A variety of empirically-based and process-based models have been proposed to build terrestrial 87Sr/86Sr isoscapes but, in their current f…
Breaking Traditions
Urnfields in the Dutch river area were replaced by cemeteries with a mixture of cremation and inhumation graves around the sixth century bc . This study provides the first biogeochemical evidence that the Iron Age communities were heterogeneous in terms of geological origins. The high percentage of non‐locally born individuals (~48%) supports the hypothesis that the change in burial practice was the result of the influx of foreign people, who wer…
A Multi-Isotope Investigation of Human and Dog Mobility and Diet in the Pre-Colonial Antilles
The complex relationships between humans and dogs (Canis lupus familiaris) have a very deep and unique history. Dogs have accompanied humans as they colonised much of the world, and were introduced via human agency into the insular Caribbean where they became widespread throughout the Ceramic Age. It is likely that the dynamic interactions between humans, dogs, and their environments in the Caribbean were spatially, chronologically, and socially …

Pollution and Oral Bioaccessibility of Pb in Soils of Villages and Cities with a Long Habitation History
The Dutch cities Utrecht and Wijk bij Duurstede were founded by the Romans around 50 B.C. and the village Fijnaart and Graft-De Rijp around 1600 A.D. The soils of these villages are polluted with Pb (up to ~5000 mg/kg). Lead isotope ratios were used to trace the sources of Pb pollution in the urban soils. In ~75% of the urban soils the source of the Pb pollution was a mixture of glazed potsherd, sherds of glazed roof tiles, building remnants (Pb …

Multi-isotope analysis of elephant ivory artefacts from Amsterdam
During the last couple of decades, excavations in Amsterdam, the Netherlands, have uncovered many artefacts from post-medieval contexts made of elephant ivory. Historical and archaeological sources show the import of great quantities of elephant ivory by the Dutch West India Company to the Dutch Republic in the seventeenth and eighteenth centuries. These sources, however, mention only the West African coast, and the Gold Coast in particular, as t…
