quartz from Evje-Iveland: trace element of high-purity quartz.
Beryl in the Horseranch Range occurs as euhedral crystals embedded in granite pegmatite dykes that cross-cut high-grade metamorphic gneiss.
At the B-Q claims, beryl occurs with dark red garnet, smoky quartz, and black tourmaline in miarolitic cavities in a granite pegmatite dykes that cuts across the foliation of a high-grade metamorphic gneiss (Wilson, 1997).
The major, minor, and trace element compositions of amphibolite, hornblende gneiss, schist, and granite pegmatite
are given in Table 2.
The mine workings are located in a west-northwest-trending lenticular granite pegmatite
which is over 100 meters in length and dips vertically or at a high angle toward the south-southwest.
1940) Mineralogy of granite pegmatites
of the Korosten pluton in Volyn and studies of ferruginous biotite.
The crystals are either collected from weathered granite pegmatites
or alluvium, or they are removed from the miarolitic cavities by the local native artisans.
Included in the introduction is also a table covering twelve of the Alabashka Granite pegmatites
and the minerals which have been found in the respective mines, and indicating each mineral's abundance in volume or weight percent.
