Field of view: 50 mm. Wolframite associated with quartz. The tabular black crystals are wolframite. The surrounding transparent host with a vitreous luster is gangue quartz.

Recovered from a quartz vein in a pneumatolytic deposit formed near the boundary between welded tuff and S-type (Ilmenite-series) granite, members of a caldera complex. Formed in the Late Cretaceous (70 Ma).

Wolframite from this location was described in 1938.
