Other/historical names associated with this locality:

Black Mountain pegmatite

Oxford pegmatite field.
Granite pegmatite.

Primarily a mica quarry with four closely spaced, nearly overlapping pits. Noted for its mineral specimen variety and for opaque pink tourmaline fans in quartz and lepidolite matrix, some of which have been over 50 cm long. No tourmaline pockets have been found at this location to date, although occasional fraudulently labeled transparent rubellite specimens have been strongly promoted as "definitely one-of-a-kind" by their sellers. Locally, these are derisively attributed to "Maine-nibia", "Maine-istan", or "Maine-zil". The eosphorite from this locality was formerly the world record size (37 mm).

The quarry is private property and is off-limits to individuals. Organized group field trips are only rarely permitted.

Not to be confused with the 'Black Mountain locality' (http://www.mindat.org/loc-6537.html).

✪ 'Tourmaline'

Formula: AD₃G₆(T₆O₁₈)(BO₃)₃X₃Z

Description: Black Mountain Mine is noted for its "fans" of pink elbaite - some as large as perhaps a foot high and across. The material is largely non-gem quality to "representative" quality. Really good quality crystals are quite rare here. It is the size and aesthetics of the "fans" which have attracted collector attention to the locality over the years.
