| This type of pegmatite, or one closely allied to it, also contains hiddenite as hypidiomorphic crystals within the pegmatite itself. |
| Large anhedral masses of yttrian fluorite, measuring to several feet across, were found at the White Cloud pegmatite. |
| They described a distorted 5.5 x 4-cm dodecahedral crystal of genthelvite from a small pegmatite near Stove Mountain. |
| The latter do not include typical pegmatite minerals and appear mainly along the tectonic fractures present at this locality. |
| The pegmatite is composed of microcline, plagioclase and quartz with minor amounts of clinopyroxene, orthopyroxene, ilmenite and zircon. |
| In places, they contain blocks and fragments of surrounding lithologies as well as isolated boudins of granite pegmatite. |
