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 cluster of almost white Barite crystals upon a matrix of grey Quartzite. Most of the Barite crystals form small flattened tabular crystals, but the main crystal is large and outstanding. It shows several growth zones and some iridescence. Most of the crystals show good clarity and a very shiny luster.
Location: Kappenbuchl Mine, Freiburg, Germany.
