In 1950-1952, construction of the Oberaar Power Station (Kraftwerke Oberaar) led to the discovery of several clefts yielding superb specimens of octahedral pink fluorite associated with quartz gwindels, adularian orthoclase crystals, and small but fine crystals of milarite
Fundortgruppe 3 is very similar, but orthoclase ("adularia"), actinolite (fibrous "amianthus"), apophyllite and zeolites are more common than in 4; milarite
is found, very rarely, in 3 alone.
Centered on a quartz crystal cluster 2 meters tall, this alcove featured a series of cases of specimens from the Alpine clefts of the Rauristal (Austria) and Ahrntal (Italy), including three astonishing milarite
specimens (one of them was pictured in "Alpine Milarite
K[Ca.sub.2]Al[Be.sub.2][Si.sub.12][O.sub.30] * 0.5[H.sub.2]O
, characterized as a species in 1870, is more familiar to micromounters than to collectors of larger specimens: crystals larger than 1 cm are rare.
Other associated minerals are: scandiobabingtonite, scandian ixiolite, hingganite-(Y), cerian epidote, titanite, plumbomicrolite and other microlite minerals, bazzite, milarite
cassiterite and two unidentified tantalum minerals (rynersonite?
The American Museum of Natural History dipped into their Bement Collection again and brought out Alpine species rarely seen, including milarite
, scheelite, lengenbachite and extremely fine anatase to name just a few.
Associated minerals are: muscovite, quartz, elbaite, topaz, milarite
, calcite, chabazite, stilbite-stellerite, rutile, fluorite, pyrrhotite, sphalerite and pyrite.
from Austria in single crystals to 1 cm would make fine and rare thumbnail specimens.
(1998) Shibkovite--the new mineral from the milarite
Carlos Barbosa, though, did have bigger supplies of bigger, better loose prisms of rich yellow-green milarite
from Jaguaracu, Minas Gerais, than previously, as well as some small miniatures with pale green glittery rounded aggregates of tiny crystals of the rare zanazzaiite, with muscovite.
In the American Museum's case, old classic specimens, mostly from the Bement collection, taught the visitor to respect Alpine-cleft (and, as it happens, Alpine) rarities like scheelite, perovskite, milarite
, and brookite; and here were four of the world's best brown anatase crystals, all from Alp Lercheltini, Valais, Switzerland.
