“…The first evidence for the presence of indium in PMD skarn ores dates back to the early 19 th century [47]. It was supported more recently [48] by numerous analyses, but Inbearing minerals and roquesite were identified much later [25] and [12][13][14][15].…”

“…The ore-forming potential of rapakivi granites on a global scale was firstly evaluated by the end of the 20th century, with several economic deposits of various types considered to be genetically associated with them [5], including unusually large tin deposits in Brazil [19,20]. Revealing indium (roquesite) mineralization in greisens from Vyborg Batholith rapakivi granites [21,22], in the skarns of the PMD [12,23], and economic concentrations of In, Bi, Be and Cd and other rare metals in PMD ores [13], provided another argument in favor of the metallogenic potential of rapakivi granites. Using up-to-date analytical methods, it has become possible to infer some formation characteristics of roquesite, bismuth sulfosalts, and helvite-group minerals during multi-stage skarn and ore formation related to the multiple discontinuous additions of hydrothermal solutions generated by SARGB granitoid formed by six magmatic pulses [5].…”

“…However, mineralogical description of PMD skarn ores, presented in many publications [10][11][12][13][14][15][24][25][26], covers mainly Sn-, Cu-, Zn-, and Fe-bearing minerals with few exceptions. In the present paper, the minerals of rare-metals (In, Bi, Be, Te, Se) and new metallogenic prospects of the PMD are described.…”

The results of the study of rare-metal (Bi, Te, Se. Be, In) mineralization of skarn deposits (Sn, Zn) in the Pitkäranta Mining District, genetically related to the Salmi anorthosite-rapakivi granite batholiths of Early Riphean age are reported. Minerals and their chemical composition were identified on the base of optical microscopy as well as electron microanalysis. The diversity of rare-metal ore mineralization (native metals, oxides, and hydroxides, carbonates, tellurides, selenides, sulfides, sulphosalts, borates, and silicates) in Pitkäranta Mining District ores is indicative of considerable variations in the physicochemical conditions of their formation controlled by the discrete-pulse-like supply of fluids. Bismuth, wittichenite, and matildite are the most common rare-metal minerals. Sulfosalts of the bismuthinite-aikinite series are represented only by its end-members. The absence of solid solution exsolution structures in sulfobismuthides suggests that they crystallized from hydrothermal solutions at low temperatures. Be (>10 minerals) and In (roquesite) minerals occur mainly in aposkarn greisens. Roquesite in Pitkäranta Mining District ores formed upon greisen alteration of skarns with In released upon the alteration of In-bearing solid sphalerite (Cu1+ In3+) ↔ (Zn2+, Fe2+) and chalcopyrite In3+ ↔ Fe3+ and 2Fe3+ ↔ (Fe2+, Zn2+) Sn4+ solutions. Sphalerite with an average In concentration of 2001 ppm, is a major In-bearing mineral in the ores.

“…Beryl, chrysoberyl, bavenite, and helvite (group) are the Be minerals present, and In is contained as a minor component in sphalerite or as a major component in roquesite (Ivashchenko et al, 2011). Both types also contain Fe, Pb, W, Bi, Ag, Au, Cd, and In.…”
