Sphalerite

Field of view: 50 mm. Sphelerite associated with diopside. The dark brown veins exhibiting perfect cleavage are sphalerite. The surrounding massive dark green host is diopside.

Recovered from a sulfide deposit in skarn formed by contact metamorphism of S-type (ilmenite-series) granite of a caldera complex in the skarn-moderate temperature hydrothermal deposit associated with the same caldera complex. Formed in the Late Cretaceous (70 Ma).

Sphalerite from this location was described in 1980.
