Barite, BaSO4 (Barium Sulfate), 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. Barite specimens from certain areas contain sand inclusions which form rosette aggregates that look like a flower. These are called "Desert Roses".
Description: This specimen consists of a pale green matrix on top of which lies a mass of crystals. The barite is the carpet of small crystals hugging the matrix surface. Many are in excellent condition, very lustrous and well formed. The larger crystals are calcite, one of which is quite large. Standing proud of the matrix are several other calcite crystals, again very lustrous.
