KLOCHITE, K 2(Fe2+Fe3+)Zn3[Si12O30], A NEW MILARITE-TYPE MINERAL SPECIES FROM THE KLOCH VOLCANO, STYRIA, AUSTRIA

Autor: Franz Walter, Christoph Hauzenberger, Walter Postl, Hans-Peter Bojar

Publikováno v: The Canadian Mineralogist. 49:1115-1124

The new mineral species klochite was found in a SiO 2 -rich xenolith from a nepheline basanite quarry at the Kloch volcano, Bad Radkersburg district, Styria, Austria. It forms hexagonal tabular crystals flattened on {001}, with a diameter up to 0.3 m

Publikováno v: European Journal of Mineralogy. 20:629-633

The new mineral struvite-(K) is the natural potassium equivalent to struvite NH4MgPO4·6H2O. It was discovered independently at two different localities: (1) at the famous sulphosalt locality Lengenbach in Binntal, Switzerland, where it occurs in a d

Trattnerite, (Fe,Mg)2(Mg,Fe)3Si12O30, a new mineral of the milarite group: mineral data and crystal structure

Autor: Walter Postl, Hans-Peter Bojar, Franz Walter, Christoph Hauzenberger, Karl Ettinger

Publikováno v: European Journal of Mineralogy. 16:375-380

The new mineral trattnerite, (Fe, Mg) 2 (Mg, Fe) 3 [Si 12 O 30 ], a member of the milarite group, occurs in small cavities of a Sirich xenolith at the hauyne-nephelinite quarry Stradner Kogel, eastern Styria, Austria. Trattnerite is hexagonal and for
