Galena

Field of view: 50 mm. Galena associated with sphalerite and kaolinite. The granular dark gray grains with perfect cleavage are galena, and surrounding massive black parts are sphalerite. The white to gray basement with a vitreous luster is gangue quartz, and the opaque white parts are earthy kaolinite. The brown parts are dirt by limonite.

Recovered from a quartz vein of a moderate-temperature hydrothermal deposit probably associated with welded tuff. Formed in the early Paleocene (65 Ma).

Galena from this location was described in 2008.
