Mineral Species: Barite

Chemical Formula: BaSO4

Chemical Name: Barium Sulfate

Mineral Class: Sulfate

Mineral Notes: Barite is easily identified by its heavy weight. Most similar minerals are much lighter. It tends to form well defined flattened crystals. Occasionally it forms large rounded mounds from precipitation of hot, barium-rich springs.

Description: A heavy, cream-coloured orthoclase matrix sporting a cluster of Barite crystals. The largest has a very unusual flattened tabular form. It is perfectly transparent and has a glassy luster. Behind are several smaller crystals arranged in parallel-running rows.
