During the 2000s this mine (sometimes incorrectly referred to as the "Khat Che" or "Khat Chay" mine) has given the world superb and distinctive crystals of phenakite
, petalite and hambergite; white to colorless though they are, these species from the Paleini mine can be quite beautiful.
Relict crystals from the leaching phase and newly grown crystals of other species formed up to 10% of the pocket contents and could include siderite, fluorite, molybdenite, topaz, columbite-(Fe), rutile, pyrite, beryl, very rarely phenakite
and other minerals.
Ever since then, intrepid collectors have been finding attractive aquamarine specimens (many of gem quality), as well as the associated secondary beryllium minerals phenakite
and bertrandite, at elevations above 12,000 feet on the steep, rocky slopes of the mountain.
The discovery of aquamarine was soon followed by the recognition of phenakite
, bertrandite, fluorite and topaz from the Mount Antero and Mount White areas.
was reported (but not described) from Alchuri by Bernard and Hyrsl (2004); however, it is unlikely to have been found there, considering the geology.
Antero (see the Tucson 2005 report), has leased a part of this famous collecting area and even now is pulling out phenakite
specimens with individual crystals to 2.5 cm: we should see these, Bryan says, in Tucson in 2007.
(1934) and PhD (1935) degrees by Harvard, on the basis of his studies on phenakite
morphology and paragenesis with Goldschmidt.
In the late 19th and early 20th centuries, some of Switzerland's best phenakite
crystals--colorless prisms to 3.8 cm, some in parallel-growth aggregates--were collected from clefts in this tiny valley, as were superb hematite roses.
Associated collectable minerals including beryl (aquamarine), green fluorite, phenakite
and bertrandite have also been found there.
in its new incarnation--as gemmy, colorless or palest yellow prisms betraying penetration twinning on the terminations--from Momeik, Mogok, Myanmar (Burma) is also familiar enough by now not to need fresh verbiage, although, unlike the brookite from Pakistan, it is not common on the market.
Dolomite and phenakite
have also been reported but have not been confirmed.
