“…The important substitutions involving Cu 2+ were clearly confirmed by the recently obtained structural data for ten minerals. There are: (i) heterovalent Cu 2+ $ Fe 3+ schemes in edtollite, melanarsite (Pekov et al, 2016b) and lyonsite (Pekov et al, 2013b), and Cu 2+ $ Al 3+ schemes in alumoedtollite; and (ii) homovalent Cu 2+ $ Mg 2+ schemes in dravertite (Pekov et al, 2017), johillerite (Koshlyakova et al, 2018) and grigorievite (Pekov et al, 2014d), and Cu 2+ $ Zn 2+ schemes in hermannjahnite (Siidra et al, 2018b), itelmenite (Nazarchuk et al, 2015) and members of the bradaczekite-zincobradaczekite series. Electron microprobe data show that significant substitutions of Cu for Mg can be realized in bradaczekite and for Zn in lammerite- (Pekov et al, 2018a), as well as in the minerals of the cryptochalcite-cesiodymite series (Pekov et al, 2018b).…”

The crystal-chemical characterization of oxysalts (sulfates, arsenates, vanadates, selenites, silicates, molybdates and borates), chlorides and oxides with speciesdefining Cu 2+ formed in volcanic fumaroles (96 minerals representing 80 structure types; 81 species are endemic to fumarolic formation) is given. Copper minerals are known only from oxidizing-type fumaroles. The most diverse copper mineralization occurs at the Tolbachik volcano (Kamchatka, Russia). Copper minerals from fumarolic systems are subdivided into two genetic groups: Group I are minerals formed in the hot zones of fumaroles (>473 K, mainly 673-973 K) and Group II are minerals formed in the moderately hot zones of fumaroles (<473 K, mainly at 343-423 K). Group I includes 81 mineral species. Their most defining chemical feature is that all of them are hydrogen-free, and many of them contain the additional anion O 2À . In comparison with minerals from other geological environments, in minerals of Group I the Cu 2+ cation exhibits the strongest affinity for four-and fivefold coordinations and the strongest distortion of Cu 2+ -centred octahedra. Group II consists of 15 chlorides and sulfates including 13 H-bearing species. In these minerals the Cu 2+ cation shows affinity for octahedral coordination, with OH À and/or H 2 O 0 as ligands. In terms of crystal chemistry these minerals are closer to supergene minerals rather than to high-temperature fumarolic species. Temperature is the major factor governing the crystal chemistry of Cu 2+ oxysalts and chlorides in low-pressure systems. The defining feature of fumarolic copper mineralization over this whole temperature range is the important role of alkali cations. The available data on complexes of Cu 2+ -centred polyhedra in the structures of natural oxysalts and halides are summarized and reviewed. Isomorphism in copper minerals from volcanic exhalations is discussed. The structures of high-temperature Cu oxysalts with additional O 2À anions (i.e. O atoms non-bonded to S 6+ , Mo 6+ , As 5+ , V 5+ , Se 4+ or B 3+ ) are also interpreted using an approach based on oxocentred tetrahedra. mineralogical crystallography Acta Cryst.

“…Large fumaroles of the 2012-2013 Tolbachik fissure eruption (e.g., Saranchinaitovaya fumarole, Naboko scoria cone) contain mineral assemblages comparable with fumaroles from the First and Second scoria cones of the Northern Breakthrough of the Great Tolbachik Fissure eruption (1975)(1976), but shows poorer mineral diversity and abundance. Nevertheless, five new sulfate mineral species were recently discovered in the sublimates of the Saranchinaitovaya fumarole: itelmenite Na 4 Mg 3 Cu 3 (SO 4 ) 8 [17], ivsite Na 3 H(SO 4 ) 2 [18], bubnovaite K 2 Na 8 Ca(SO 4 ) 6 [19], hermannjahnite CuZn(SO 4 ) 2 [20], and saranchinaite Na 2 Cu(SO 4 ) 2 [21]. Other minerals are represented by anhydrite, chalcocyanite, euchlorine, thénardite, aphthitalite and hematite [20,21].…”

Copper-Containing Magnesioferrite in Vesicular Trachyandesite in a Lava Tube from the 2012–2013 Eruption of the Tolbachik Volcano, Kamchatka, Russia

et al. 2018

View full text Add to dashboard Cite

Cu-rich magnesioferrite was found in vesicular basaltic trachyandesite in one of lava tubes (Duplex) that formed during the 2012–2013 eruption of the Tolbachik volcano, Kamchatka. This mineral is commonly associated with hematite, tenorite, halite, sylvite, and Ca-rich silicates (mainly, esseneite and Na-rich melilite) in high-temperature (800–1000 °C) reactionary zones (up to 100 µm) covering vesicular rocks and lava stalactites in the Duplex tube. The mineral relationships of this assemblage indicate the following crystallization sequence: Ca-rich silicates + hematite → Cu-rich magnesioferrite → tenorite → chlorides. This formed due to the reaction of hot gases containing Cu, alkalis, and Cl with solidified lava rock. The composition of magnesioferrite varies strongly in CuO (5.8–17.3 wt %; cuprospinel end-member—15–47 mol %), whereas the contents of other oxides are minor, indicating the main isomorphic substitution is Mg2+ ↔ Cu2+. Compositions with maximal CuO content nominally belong to Mg-rich cuprospinel: (Cu0.48Mg0.41Mn0.09Zn0.02Ca0.02) (Fe3+1.94Al0.03Ti0.02)O4. Increasing CuO content of the Duplex Cu-rich magnesioferrite is reflected in Raman spectra by moderate right shifting bands at ≈700–710 and 200–210 cm−1 and the appearance of an additional band at 596 cm−1. This supports the main isomorphic scheme and may indicate a degree of inversion in the spinel structure.
