Kopruden alinan ozgun tugla numuneleri uzerinde yapilan minerolojik ve mikrokimyasal analizler (XRF-XRD) neticesinde ozgun tugla numunesinin Bavenite
The typically Alpine associations include crystals of quartz, white tabular calcite, apatite-(CaF) and bavenite
(Stroh, 1985; Niedermayr, 1986,2002).
Other minerals present containing the element include bavenite
, beryl, genthelvite, milarite, and helbertrandite.
These include Baveno, type locality of six mineral species and whose name immediately calls to mind the beryllium mineral bavenite
and the baveno twinning in feldspar; the alpine rodingite localities (Val d' Ala, Valle di Viu, Valle di Susa, Bellecombe etc.
The Londonderry feldspar pegmatite has been a well known source for gem petalite, excellent ixiolite and columbite crystals, and the rare minerals eucryptite, bavenite
, bityite and moraesite.
it) had a choice selection of uncommon minerals: bavenite
crystals from Cadalso de los Vidrios, Spain, blue henmilite crystals from the Fuka mine, Bicchu-cho, Japan, some good specimens of the uncommon arsenate vladimirite from Irtem, Morocco and various other minerals from worldwide occurrences.
In the Ermakovskoye deposit in the Ural Mountains, split prismatic crystals of milarite to 4 cm long occur with bavenite
Vinals, personal communication), schorl, axinite, apatite, bavenite
Along with gem spodumene and tourmaline, Jahns and Wright (1951) list quartz, perthitic microdine, albite, beryl (morganite and aquamarine), bavenite
, bertrandite, numerous bismuth-containing minerals including native bismuth, bismuthialte, bismutite, and bismite, and nurnerous phosphates including lithiophilite, triphylite, sickletite, purpurite, heterosite, stewartite, and hureaulite.
Included were laumontite crystals to 4 cm, in clusters lacking matrix, large plates of botryoidal prehnite from the Castilla quarry, and up to 1-cm tufts of bavenite
on feldspar crystals from the Los Gallegos quarry.
Nice micromounts of milarite, bavenite
and manganite have also turned up.
Other material included massive bavenite
(to several cm
