Baryte

Field of view: 10 mm. Baryte perched on jordanite. The tabular transparent crystals are baryte. The surrounding host is jordanite encrusted with white clay.

Recovered from an open space of a sulfide vein of a moderate-temperature hydrothermal deposit associated with rhyolitic welded tuff in a caldera complex. Formed in the late Pliocene (3.5 Ma).

Baryte from this location was described in 1896.
