Elements
Arsenic As Locality: on a dump of Alsó-Rózsa adit, Nagybörzsöny, Börzsöny Mts. Description: rare, black films or thin coatings on bismuth aggregates; or as microscopic inclusions in bismuth.
Sulphides
Altaite – PbTe, coloradoite – HgTe, colusite – Cu26V2(As, Sn, Sb)6S32, kuramite – Cu3SnS4, mawsonite – Cu6Fe2SnS8, melonite – NiTe2, petzite – Ag3AuTe2, stannoidite – Cu8(Fe, Zn)3Sn2S12 and sylvanite – (Au, Ag)2Te4. Locality: Lahóca Hill, Recsk, Mátra Mountains. Description: microscopic minerals in massive enargite-luzonite ores.
Halides
Bischofite MgCl2 • 6 H2O Locality: -700 m level of Recsk ore mine, Mátra Mountains. Description: fine grained yellowish aggregates or crusts have been detected as recent precipitations in association with other halides and sulphates
Eriochalcite CuCl2 • 2 H2O Locality: -700 m level of Recsk ore mine, Mátra Mountains. Description: minute crystals (less than 1 mm) were detected as recent precipitations together with other halides and sulphates.
Carbonates
Claraite (Cu, Zn)3(CO3)(OH)4 • 4 H2O Locality: Andrássy-I. mine, Rudabánya. Description: greenish blue and pale green, globular aggregates to 1-2 mm, which consist of radial intergrowth of very minor lath shaped crystals.
Sulphates
Bonattite CuSO4 • 3 H2OLocality: -700 m level of Recsk ore mine, Mátra Mountains. Description: rare, minute blue globular aggregates associated with eriochalcite and northupite.
Botryogen MgFe3+(SO4)2(OH) • 7 H2OLocality: Andrássy-III. mine, Rudabánya. Description: rare, pale orange aggregates and crusts (up to 3-5 mm), as recent precipitates. Accompanying minerals include copiapite, epsomite, melanterite, and gypsum.
Magnesiocopiapite MgFe4(SO4)6(OH)2 • 20 H2OLocality: Rudabánya. Description: yellow to yellow-brown crusts (up to 5 cm) in association with gypsum, hexahydrite, and copiapite.
Serpierite Ca(Cu, Zn)4(SO4)2(OH)6 • 3 H2OLocality: Rudabánya. Description: rare, sky-blue sprays (up to 1 mm) were detected on tennantite.
Sideronatrite Na2Fe3+(SO4)2(OH) • 3 H2OLocality: -700 m level of Recsk ore mine, Mátra Mountains. Description: orange to orange-brown crusts or globular aggregates (up to 2 mm diameter), consisting of small needle together with other sulphates and halides
Arsenates
Bayldonite PbCu3(AsO4)2(OH)2 • H2OLocality: Meleg Hill, Nadap, Velence Mountains. Description: yellow-green crusts and globular aggregates (up to 1-2 mm) in cavities of hydroquartzite, as an alteration product of enargite, associated with plumbojarosite, cornubite, and other arsenates.
Kankite Fe3+AsO4 • 3,5 H2O Locality: Nagybörzsöny, Börzsöny Mountains. Description: a rare alteration product of arsenopyrite. It forms porous yellow-green botryoidal crusts, in close association with scorodite.
Silicates
Edenite NaCa2(Mg, Fe2+)5Si7AlO22(OH)2 Magnesiohastingsite NaCa2(Mg, Fe2+)4Fe3+Si6Al2O22(OH)2 Magnesiohornblende Ca2(Mg, Fe2+)4Al(Si7Al)O22(OH, F)2 Tschermakite Ca2(Mg, Fe2+)3Al2(Si6Al2)O22(OH)2 Locality: rock-forming minerals in Eocene andesites at Komló, Recsk and Velence Mountains. Description: they were detected by electron-microprobe analyses of amphibole crystals of andesites.
Clinozoisite Ca2Al3(SiO4)3(OH) Locality: in several metamorphic rocks of the Sopron Mountains. Description: microscopic grains.
