“…According to the latest studies the Rudabánya ore deposit complex was formed in several periods. Three main deformation phases divided temporally the periods of ore formation (Földessy et al 2010;Németh et al 2013). A synsediment, stratiform, sedimentary-exhalative Pb-Zn-barite accumulation was formed in the pelitic and carbonatic, reductive Szin Marl as the earliest ore forming phase.…”

Azurite, a historical blue mineral pigment, has previously been described to contain certain elemental impurities. These may originate from host rocks, vein fillings, or the primary copper ore mineralization. In this study, azurites (and also green malachites) from three important Central European deposits with a potential of being exploited for pigment usage already in the Middle Ages have been studied, together with azurite from Chessy, France, with a different geological setting. Using electron probe microanalysis and, more importantly, laser ablation inductively coupled plasma mass spectroscopy for trace elemental analysis, several indicators were pinpointed as important for provenance: characteristic elemental fingerprint of the deposit, e.g., elevated lead (Pb) in combination with rare earth elements, may be combined with zinc (Zn)/arsenic (As) ratio (indicating sources of excess Zn in the primary deposit) and the overall amount of metal impurities (suggesting the source mineral of copper for azurite formation). In addition, malachites from the same deposits were found to preferentially incorporate primary ore metal elements as well as Cd, Mg, Mn, or U. Therefore, if azurite pigment contains an elevated amount of malachite as an impurity, it may significantly influence the overall elemental composition. The results obtained on geological samples were applied to two micro-samples of works of art containing azurite-rich layers originating from the 13th–14th and 16th centuries. It was shown that it is highly beneficial to focus on the overall trace elemental composition of the paint layer and not on the admixed mineral grains, as their presence, especially in minute micro-samples, is largely accidental and thus not representative. Although a higher number of samples need to be studied in the future, the newly described criteria made it possible to exclude some of the localities of the employed azurite pigment. This confirmed the key importance of trace elements analysis of mineral pigments for the provenance studies of fine arts.

We point to sulphosalt ores as the main source of metal for the Fi nal Neo lithic/Early Bronze Age cop per artefacts from south ern Po land. The in clu sions, rich in Ag, As, Sb and Sn, doc ument the type of ore, re gard less of the met al lur gi cal pro cess lead ing to de ple tion of As and Sb. The cop per metal should contain nei ther Sb nor As, hence both of these el e ments, if orig i nally pres ent in ore, can be pre served only in in clu sions. The con cen tra tions of Ag, Sb, As and Sn in the artefacts in ves ti gated, the pres ence of in clu sions, and their chem i cal com po si tion, are the key in di ca tors for the de ter mi na tion of the min er al og i cal com po si tion of the orig i nal ores. Given the high con cen trations of Sb, As and Ag in the Cu metal and min er al ogy of the in clu sions, the ore must have con tained vary ing pro por tions of Ag-bear ing tetrahedrite (Cu,Fe) 12 Sb 4 S 13 and ten nan tite (Cu,Fe) 12 As 4 S 13 . Min er al og i cal com po si tions of the cop per ores in dicate the de pos its in Slovakia (Špania Dol ina) as the source of metal for the artefacts in ves ti gated. The re sults of Pb and Cu iso to pic anal y ses car ried out for this study sup port those con clu sions.
