“…A batch media made of slaked lime/slaked magnesian lime, bone white, and white antimony was involved in all colors. The presence of rare pigments, such as stibnite and white antimony, can be explained by the close proximity of the town to the Ural Mountains, with a large variety of mineral deposits [76][77][78].…”

“…The location of the island town of Sviyazhsk, with its proximity to the various mineral deposits in the Ural Mountains [76][77][78] and its intersection with the "Volga Route" and the "Silk Road", offered it pigments and minerals otherwise rare, such as malachite, azurite, arsenic, lead, and antimony. In the Southern Urals, in the second millennium B.C., people produced antimony-lead-cooper alloys [79].…”

Twenty frescoes from “The Assumption” Cathedral located in the island town of Sviyazhsk (Tatarstan Republic, Russian Federation)—dated back to the times of Tsar Ivan IV “the Terrible”—were chemically analyzed in situ with a portable X-ray fluorescence (pXRF) spectrometer. The investigation focused on identifying the pigments and their combinations in the paint recipes. One hundred ninety-three micropoints randomly chosen from the white, yellow, orange, pink, brown, red, grey, black, green, and blue areas were measured for major and minor elements. The compositional types separated within each color indicate different recipes. The statistical processing of the data unveiled the most important oxides (CaO, MgO, Fe2O3, PbO, SO3, Sb2O3, Al2O3, SiO2, and P2O5) and their relationships. The results allowed to infer the mineral composition of the paints, and, hence, the recipes used by the Russian artisans. Slaked lime and slaked dolomitic lime mixed with variable amounts of “antimony white” and “bone white” were used for white, pink, yellow, and orange paints and for preparing a basic batch for all other colors. Mostly yellow ochre, red ochre, and lead minerals, and occasionally blue ochre, green earth, realgar, orpiment, bone black, galena, stibnite, and magnetite were the pigments involved in various amounts in preparing the paints.

“…[26]. Metamorphic mineral assemblages of the host mainly metasedimentary rocks indicate the amphibolitic facies of the metamorphic peak that was assumed to be associated with the Early-Permian regional metamorphism, accompanying the hyper-collision [89,90]. Five stages of ore formation can be distinguished (cf., [21]): (I) deposition of terrigenous and volcaniclastic rock (slightly enriched in Au), Late Fransian-Early Visean, (II) low-grade greenstone metamorphic stage with disseminated sulphide redistribution, Tournaisian, (III) main collision metamorphism (amphibolitic facies) and formation of the synorogenic tonalite-granodiorite pluton and pegmatite and quartz veins in its apical part and, further from the pluton, in the distal peripheral zone, series of gold-scheelite-sulphide-quartz veins accompanied by beresite-listvenite alteration, Visean-Serpukhovian, (IV) formation of veinlet-disseminated gold-telluride mantle-related mineralisation, Moscovian-Early Permian, and (V) supergenic stage with the formation of weathering crust and large gold placers (Mesozoic-Cenozoic).…”

The large gold-telluride Svetlinsk deposit (~135 t Au) is considered to be a nontraditional one in the Urals and its origin is debated. A specific feature of the deposit is the abundance of various tellurides, such as tellurides of Fe, Ni, Pb, Sb, Bi, Ag, and Au. The new data of microthermometry, Raman spectroscopy, LA-ICP-MS, and crush-leach analysis (gas and ion chromatography, ICP-MS) for fluid inclusions as well as O-isotope data for quartz were obtained for the construction of PTX parameters of ore-formation and fluid sources in the deposit. Mineralisation was formed at a wide range of temperature and pressure (200–400 °C, 1–4 kbar) and from contrasting fluids with multiple sources. At the early stages, the magmatic fluid evolved during its ascent and phase separation and the fluid derived from the host rock decarbonation and dehydration were involved in the hydrothermal system. In addition, mantle-derived fluid might be involved in the ore-forming process during gold-telluride precipitation as well as heated meteoric waters during the late stages. Early fluids were rich in H2S, S0, and CH4, while the Au-Te mineralisation was formed from N2-rich fluid.

Abstract. The period of official activity of the EUROPROBE commission was conducted in the Urals with implementation of the URALIDES program, which stimulated many qualified geologists from western research institutes and universities to come to the region and work with local geologists on topical problems of Uralian geology. The author aims to answer questions as to what interesting results have been obtained in the Southern Urals in the last decade, after most foreign researchers left the Urals, and how these results correspond to the scientific conclusions that had been reached before.
