Crystallized fluorite on quartz epimorphs after calcite. On private ranch land.

Several generations of fluorite were deposited in an area of karst limestone. The largest pocket found so far measured 1X1.5X4 meters! Fluorite octohedrons and cube-octohedrons coat quartz casts after calcite. The original calcite crystals varied in habits, producing hollow fluorite-lined epimorphs of scalenohedral, rhomb, and acute rhomb shapes. Locality produces an abundance of ochsenaugen (English = ox eyes), a rare form of rounded fluorite crystals.
