Neat combination specimen consisting of a cluster of colorless gemmy halite crystals to 4.0 cm in size, these hosting crystals of gypsum. In good condition all around.Bleicherode, located in the Nordhausen district of Thuringia, Germany, has a rich industrial and mining history centered around extensive potash and rock salt deposits. Geologically, the area is part of the Zechstein Basin, where large evaporite formations accumulated during the Late Permian period as ancient shallow seas repeatedly evaporated, leaving behind thick layers of halite, carnallite, and sylvite. Mining operations began in the late 19th century, with the sinking of the first potash shafts around 1899, and the town quickly developed into a major center for German fertilizer production and salt extraction. The mines operated through various political eras of the 20th century before production gradually wound down, concluding industrial extraction in the unified post-war era, though the legacy of the local potash industry remains deeply tied to the region's industrial heritage.
