- Burbankite, Sodalite, Galena
- Small Cabinet, 5.1 x 4.3 x 4.0 cm
- Cerro Sapo, Ayopaya Province, Cochabamba Department, Bolivia
The Cerro Sapo area (the following is quoted from MINDAT) "is one of the few alkaline provinces in the Andes. The interesting minerals are from a large dike, 2km long, 1 - 5m wide, of pegmatitic ankerite-sodalite-Baryte carbonatite, which cuts a nepheline syenite intrusion and the surrounding hornfels and slate. Source of all the sodalite beads found in Inca and pre-Inca ruins ranging from Quito (Ecuador) to Tucuman (Argentina) ." The mostly albite matrix is highlighted by blue sodalite and metallic-bright galena crystals, but this excellent combination specimen also contains the rare cerium carbonate, burbankite (reddish), plus brown ankerite and dawsonite and white hisingerite. Very representative and rare combination material from this uncommon locale. Ex. Wes Parker Collection.
