“…Famous examples are the wrecks of the historical warships Vasa, Stockholm, Sweden, and Mary Rose, Portsmouth, U.K., for which the hull timbers accumulated bacterially transformed reduced sulfur compounds on the seabed, together with iron(II) ions from the corroding iron bolts. [1][2][3][4][5] Museum objects of waterlogged wood are nowadays mostly impregnated with polyethylene glycol (PEG), a consolidation agent that replaces water in the wood cavities to mechanically stabilize the weakened structure when drying. The Vasa was the first major object to be treated with PEG.…”

“…2,3 Analyses with sulfur XANES and SXM on fresh wood, treated in laboratory experiments to simulate the conditions of shipwreck sites, confirm that the speciation, composition and distribution of sulfur compounds are similar to those in authentic marine-archaeological wood. 4 X-Ray imaging techniques can also be used for evaluating the efficiency of conservation treatments. Synchrotron radiation-micro computer tomography (SR-μCT) was used to visualize the 3D microstructure of wood treated with different consolidation agents, including PEG, to study the distribution, depth of penetration and degree of cavity-filling.…”

“…There is an enormous breadth of problems to which the technique has been applied; ranging from the origin of Ancient Greek (5th century BCE) burial vessels [20], to the deterioration of medieval stained glass windows [21], to degradation of historic documents by iron gall ink [22] and to the origin of van Gogh's yellow paint [23]. Artefacts that have been a particular focus for XAS studies are waterlogged archaeological timbers, namely the historic ships the Vasa [24][25][26][27][28][29][30][31] and the Mary Rose [32][33][34][35][36][37][38][39][40]. It is this latter ship that has been of interest to the current group of authors with a special interest in the 'sulfur problem'.…”

We report a microfocus X-ray absorption (XAS) investigation of a thin film sample from an iron contaminated wooden arrow tip raised from the seabed with the Mary Rose. The XAS studies were combined with optical and scanning electron microscopy measurements. The arrow tip had been treated with polyethylene glycol (PEG) soon after it had been raised and stored in a controlled environment. The measurements revealed a significant concentration of iron sulfide nanoparticles. This indicates that in this sample there was a reduction of the oxidative effects of the normal ambient atmosphere that is usually seen in untreated timbers. The film was treated overnight with an aqueous solution of diethylenetriaminepentaacetic acid (DTPA), which is normally very effective in sequestering iron. This had little effect in terms of removing iron from the film and possible explanations are discussed.

“…La formation de sulfures de fer lors de processus de corrosion anoxique constitue une problématique majeure que ce soit pour la conservation d'objets archéologiques in situ sur leur site d'enfouissement [1][2][3] ou pour la prévision de la durée de vie d'ouvrages métalliques enfouis dans les sols tels que les oléoducs [4,5] ou encore les barrières en acier non ou faiblement allié, surconteneurs et chemisage, prévus dans le cadre du stockage des déchets nucléaires de haute activité en milieu géologique profond [6,7]. En effet, la formation de sulfures de fer est susceptible de modifier les processus de corrosion.…”

Résumé -Cetteétude est consacréeà la détermination de l'origine biotique ou abiotique de sulfures de fer formés au cours de processus de corrosion anoxiques par l'analyse de la composition isotopique du soufre. Usuellement ces analyses sont réalisées par IRMS (Isotopic Ratio Mass Spectrometry) sur des sulfures et des sulfates préalablement dissous. Dans cetteétude, en revanche, une nouvelle approche est utilisée, basée sur des analyses isotopiques locales de surface réalisées en nanoSIMS afin de conserver l'information sur la localisation des produits de corrosion. Deux types d'échantillons ontétéétudiés : unéchantillon (CBCC) corrodé pendant 13 mois en conditions contrôlées, et unéchantillon archéologique corrodé pendant environ 2000 ans dans des conditions mal connues. Lorsque le système de corrosion est parfaitement connu, tel que le cas de l'échantillon CBCC, l'analyse isotopique locale par nanoSIMS permet effectivement de conclure sur la (bio-)origine des liserés de sulfures de fer formés. En revanche, lorsque la composition isotopique de la source de sulfates est inconnue, comme dans le cas de l'échantillon archéologique, il n'est pas toujours possible de conclure sur l'origine des sulfures de fer observés. Mots clés : Corrosion anoxique / sulfures de fer / bactéries / fractionnement isotopique du soufre / nanoSIMSAbstract -Characterisation and determination of the bio-origin of iron sulphides in anoxic corrosion systems thanks to isotopic analyses by nanoSIMS. This study is devoted to the determination of the bacterial or inorganic origin of iron sulphides formed during anoxic corrosion processes by sulfur isotopic composition analyses. Broadly, these analyses are realized by IRMS on dissolved sulphides and sulphates. Yet in this study, surface local isotopic analyses are realized by nanoSIMS in order to preserve the information about the corrosion products' localization. Two kinds of samples are studied: a sample (CBCC) corroded during 13 months in controlled laboratory conditions; and one archeological sample corroded during about 2000 years in not very well known conditions. When the corrosion system is perfectly well known, as for the CBCC sample, the local isotopic analyses by nanoSIMS actually enable to conclude on the (bio-)origin of the iron sulphides observed. However, when the isotopic composition of the sulphate's source is unknown, as for the archeological sample, the origin of iron sulphides cannot always be determined.
