Mining Archaeology and Micro‐Raman Analysis Associated with ESEM‐EDX: Toward a Chrono‐Spatial Definition of Ore Consumption in a Pyrenean Medieval Workshop, 14th–16th Centuries

The rapid expansion of non-ferrous metallurgy in the late Middle Ages (14th-15th centuries) enhanced ore demand, which was supported by mining intensification. Metallurgical workshops developed various supply strategies based on geological, political and economic constraints. This is particularly true for the Pyrenean multi-metals workshop of Castel-Minier (Ariège, France), where recent excavations unearthed an exceptional corpus of non-ferrous ores. A specific analytical methodology combining micro-Raman spectroscopy and environmental scanning electron microscopy with energy dispersive X-ray (ESEM-EDX) was set up to study these artefacts. This composite methodology permitted the fast characterization of both mineral and gangue as well as a discussion of their economic potential. Ores identified were compared with ancient mines in neighbouring mining districts in order to sketch a geography of the mineral resources available to medieval metallurgists. Moreover, a chronostratigraphic study of ore distribution in Castel-Minier revealed the supply strategies, technological choices as well as spatializing of copper and lead metallurgies.

“…Even if their sensitivity is less than thta of the laboratory experimental setup, commercial XRF devices offer the opportunity to gather information "at home" regarding the presence of different heavy elements such as Pb in bone [56], Zn in human toenail clipping [57] and human nail [58], Cr [59] and Fe [60] in skin, Zr in [61], tooth abnormalities (pulp stones) [62][63][64], the determination of Fe in blood [65] or the presence of Pu (Plutonium) for workers decommissioning the Fukushima Daiichi nuclear power plant [66]. Practically a portable XRF setup (Figure 4) can be used for solid metals and alloys, ores and soils [67]. Using a gold anode X-Ray generator, under 50 kV high voltage excitation, it offers a powerful source and highly sensitive measurements.…”

This contribution tries to indicate to the clinician what kind of information can be investigated through X-ray fluorescence, what kind of information can be extracted from this spectroscopy and finally how it competes with other tools described in previous publications such as Fourier Transform Infrared or Raman spectroscopy, X-ray Absorption Near Edge Structure spectroscopy and X-ray diffraction. To attain this goal, several examples based on X-ray fluorescence experiments performed on biological samples namely concretions, medical devices, biological fluids as well as tissues are presented.Résumé. Cette contribution vise à sensibiliser le clinicien sur l'utilisation de la spectroscopie de fluorescence X en précisant le type d'échantillon pouvant être étudié et les informations exploitables. De plus, la complémentarité avec d'autres techniques analytiques présentées dans des publications précédentes, telles que les spectroscopies vibrationnelles (spectroscopie infrarouge à transformée de Fourier et Raman), la spectroscopie d'absorption des rayons X et la diffraction des rayons X est discutée. Différents résultats de mesures par spectroscopie de fluorescence X effectués sur des échantillons biologiques de différentes natures (concrétions, dispositifs médicaux, fluides et tissus biologiques) sont présentés.

“…More recently, geochemistry has experienced an increase in interest from archaeologists in search of new methods to investigate the internal spatial organization of sites and/or to determine the specific function of features, structures or spaces within sites. Geochemical data responding to these objectives has been and is being provided by the development of new technologies and techniques including: phosphate concentration (Crowther, 1997;Holiday & Gartner, 2007;Parnell, Terry, & Golden, 2001;Roos & Nolan, 2012;Rypkema, Lee, Galaty, & Haws, 2007), inductively coupled plasmaoptical emission spectroscopy (ICP-OES) (Dirix et al, 2013;Middleton & Price, 1996;Oonk, Slomp, Huisman, & Vriend, 2009a;Vyncke, Degryse, Vassilieva, & Waelkens, 2011;Wilson, Davidson, & Cresser, 2008, inductively coupled plasma-atomic emission spectrometry (ICP-AES) (Knudson, Frink, Hoffman, & Price, 2004;Linderholm & Lundberg, 1994), inductively coupled plasma-mass spectrometry (ICP-MS) (Cuenca-García, 2015;Huisman, 1998;Misarti, Finney, & Maschner, 2011), and laboratory-based and portable Xray fluorescence (pXRF) spectrometry (Booth et al, 2017;Ciminale, Gallo, Pallara, & Laviano, 2009;Cook, Clarke, Fulford, & Voss, 2014;Coronel, Bair, Brown, & Terry, 2014;Cuenca-García, 2015De Langhe, 2015;Frahm et al, 2016;Huisman, 1998;Hunt & Speakman, 2015;Janovský & Horák, 2018;Oonk, Slomp, Huisman, & Vriend, 2009a, 2009bTereygeol, Arles, Foy, Florsch, & Llubes, 2010;Vos, Jenkins, & Palmer, 2018).…”

Over the past several decades the geochemical study of archaeological sediments has experienced an increase in interest from archaeologists in search of new methods to investigate spatial organization and space function. Used with other proxies like geophysics, archaeobotany and micromorphology, geochemistry provides a new insight into microscopic pollution generated by past human activities, and thus can explain or confirm the function of features and spaces. Portable X‐ray fluorescence (pXRF) spectrometry offers new perspectives to the archaeological community to test, develop and integrate geochemical surveys in the daily routine of fieldwork, especially in the developer‐funded archaeology sector. We have undertaken over 20 geochemical surveys using pXRF spectrometry, both in the field and on bulk samples, and from a wide variety of sites, sedimentological, and chronological contexts. Working exclusively on developer‐funded projects, we present a series of results detailing a range of chemical element associations, including details on how the data is organized spatially and how these data may be interpreted. For some associations, such as that between phosphorus, calcium and strontium, our work confirms and builds on existing studies. For other elements such as zirconium, or the association between potassium, chromium and vanadium, our work presents new data patterns as well as a series of new hypothesis; the interpretation of these patterns remains at an early stage and we hope that further work will be done to test and detail the origins of these chemical associations and enrichments, with the goal of confirming the human activities and/or natural processes from which they originated. The rapidity and cost‐efficiency of pXRF, especially when used in situ in the field, makes it the ideal method for documenting the geochemical characteristics of landscapes; the approach we have developed means that geochemical survey can become a regular part of archaeological practice.
