Abstract: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, … Show more
“…The only cation substitutions recorded in matildite are Pb (1.42 wt.% on average, varying from undetectable to 18.63 wt.% in the Pitkäranta Mining District, Russia; Ivashchenko, 2021), Cu (0.93 wt.% on average, varying from below detection limit to 7.75 wt.% at the Berezovsk Gold Deposit in Russia; Vikentieva et al ., 2008), and minor Fe, with a single value of 1.65 wt.% reported in Greece (Triantafyllidis, 2019), but mostly below the detection limit (Table 1). Sulfur is substituted by Se (0.921 wt.% on average for a maximum of 4.94 wt.% at the Ikuno deposit in Japan; Shizimu et al ., 1998); Te has not been documented in matildite.…”

“…This compilation corresponds to 17 sources (for 15 localities) for bohdanowiczite, from the original new mineral paper (Banas et al 1979) to the latest available paper (Cabral et al 2017). For matildite, 8 sources were discovered, ranging from original description (reported in Palache et al 1944) to the latest available paper (Ivashchenko 2021). There might be other sources of information regarding the chemistry of both bohdanowiczite and matildite, but we were able to discover only those listed here (Table 1).…”

“…This compilation represents 17 sources (for 15 localities) for bohdanowiczite, from the first report describing the new mineral (Banas et al ., 1979) to the latest available paper (Cabral et al ., 2017). For matildite, eight sources have been compiled, ranging from the original description (reported in Palache et al ., 1944) to the latest available paper (Ivashchenko, 2021). The averages, minimum and maximum values for all literature data on bohdanowiczite and matildite, and for the matildite–bohdanowiczite solid-solution mineral from the Photo Lake deposit in Canada (this work) are reported in Table 1.…”
A high-grade ore sample from the Cu-Zn-Au Photo Lake volcanogenic massive sulfide deposit (Flin Flon-Snow Lake greenstone belt, Manitoba, Canada) contains a Bi-Ag sulfo-selenide situated approximately in the middle of the S-Se substitution range (Se~0.86 apfu, S~1.05 apfu). These new data, combined with a literature compilation of all publicly available matildite and bohdanowiczite mineral chemistry data, reveal a nearly complete range of S-Se substitution between these two minerals, with only the section between BiAgSe 0.78 S 1.18 and BiAgSe 0.25 S 1.75 -about a quarter of the full S-Se range -not documented. These findings suggest that a complete solid solution series between matildite and bohdanowiczite may exist, as previously suspected and in a manner similar to the galena -clausthalite complete solid solution series.
