Celestine with Sulfur

specimen number:
1362030

location:
Machow mine, Tarnobrzeg, Subcarpathian Voivodeship, Poland

description:

Aesthetic example from this classic Polish locality. A spray of sparkling barian rich celestine crystals measuring 4.0 cm in diameter are set nicely up on matrix with crystalline yellow native sulfur. In super condition.

The Machow mine, located near Tarnobrzeg in southeastern Poland, was historically one of the most prominent open-cast native sulfur mining operations in Europe. Discovered in 1953, large-scale industrial extraction began in 1970 and continued until the late 20th century, after which the massive excavation was successfully closed, reclaimed, and transformed into a recreational lake. Geologically, the deposit lies within the Carpathian Foredeep and formed through secondary processes where microbial action and hydrocarbons reduced underlying Miocene sulfate beds, such as gypsum and anhydrite, depositing native sulfur within vuggy post-gypsum limestones. Mineralogically, the mine became world-famous among collectors for producing exceptional, vivid canary-yellow sulfur crystals associated with fine specimens of celestine, calcite, baryte, and gypsum.
