New mineral species for Hungary in 2009

Native elements

Belendorffite - Cu₇Hg₆, Trigonal

Locality: Andrássy-I. mine, Rudabánya.
Description: Silver white (fresh), then bronze, later dull dark brown films, encrustations, rarely equant crystals in massive cuprite. It is often seen at the border between cuprite and native copper. Beyond these minerals native mercury can be observed in its environment.
Collector: Gábor Koller (Szentendre).
Examinations: XRD (Ferenc Kristály, University of Miskolc) and EDS (Norbert Zajzon, University of Miskolc).

Sulphides

Imiterite - Ag₂HgS₂, Monoclinic

Locality: Andrássy-III. mine, Rudabánya.
Description: Grains up to some microns in massive acanthite in limonite ore. Associated minerals are cinnabar and cerussite.
Collector: János Éhik (Szuhogy).
Examination: EDS (Norbert Zajzon, University of Miskolc).

Roxbyite - Cu₉S₅, Monoclinic

Locality: Andrássy-I. mine, Rudabánya.
Description: Dark steel blue, fine grained aggregates cementing pyrite grains.
Collector: János Éhik (Szuhogy).
Examinations: XRD and EDS (Sándor Szakáll, University of Miskolc).

Rucklidgeite - (Bi, Pb)₃Te₄, Trigonal

Locality: dump of the Péter-Pál shaft, Gyöngyösoroszi, Mátra Mts.
Description: Lamellar aggregates consisting of tin white, tabular crystals up to 0.4-0.7 cm together with tetradymite in quartz-calcite veins. The studied material does not contain lead, but tellurium is accompanied by selenium.
Collector: Tibor Horváth (Budapest).
Examination: WDS (Gábor Papp, Hungarian Natural History Museum, Budapest).

Halides

Claringbullite - Cu₄Cl(OH)₇, Hexagonal

Locality: Andrássy-I. mine, Rudabánya.
Description: Light blue, lamellar aggregates up to 0.5-1 mm in cavities of cuprite. It is associated with ink blue connellite.
Collector: Gábor Koller (Szentendre).
Examination: XRD (Béla Fehér, Herman Ottó Museum, Miskolc).

Oxides

Pyrophanite - MnTiO₃, Trigonal

Locality: Perkupa.
Description: Equant crystals up to 50-100 microns in serpentinite. In cores of the crystals sometimes perovskite can be observed.
Collection: Herman Ottó Museum (Miskolc).
Examination: EDS (Norbert Zajzon, University of Miskolc).

Sulphates

Ammoniomagnesiovoltaite - (NH₄)₂Mg₅Fe³⁺₃Al(SO₄)₁₂ • 18H₂O , Cubic

Locality: Vasas open-cut coal mine, Pécs, Mecsek Mts.
Description: Pale yellow to brownish yellow, octahedral or octahedral-hexahedral crystals up to 0.2 mm in diameter with vitreous lustre as well as loose crusts consisting of above described crystals. It is a recent secondary mineral on dump of an abandoned coal mine, which is associated with varied ammonium-bearing sulphate minerals, mainly tschermigite, mohrite, clairite, boussingaultite and godovikovite. This new mineral has been approved by IMA CNMNC (IMA no. 2009-040).
Collector: Csaba Papp (Pécs).
Examinations: publication is under construction (Sándor Szakáll and István Sajó).

Silicates

Chabazite-Mg - Mg_0,75K_0,50Ca_0,50[Si₉Al₃O₂₄] • 10H₂O, Trigonal

Locality: Kalapos Hill, Bazsi, Balaton Highland.
Description: Colourless, water clear, rhombohedral crystals up to 0.5 mm in diameter with vitreous lustre. It was found in cavities of basalt, where the crystals seat on thin, pale brown saponite crust. This new mineral has been approved by IMA CNMNC (IMA no. 2009-060).
Examinations: publication is under construction (Giovanna Vezzalini and co-workers).
