This gypsum specimen comes from a former lignite open-pit mine near Neuenhain in the Borken lignite mining district of northern Hesse, Germany. An approximately 6 cm long, partly transparent main crystal is accompanied by several smaller gypsum crystals. <\/p>\n

The main crystal shows a double-terminated form with clearly defined crystal faces. Additional gypsum crystals occur along the sides and at the base, some of them arranged in fan-shaped groups. White to brownish inclusions and surface deposits produce irregular zoning, particularly along the edges. <\/p>\n

With a length of approximately 6 cm, the piece belongs to the small cabinet specimen size category.<\/p>\n

Gypsum from the Former Borken Lignite Mining District<\/h3>\n

Numerous gypsum crystals were recovered from the Borken lignite mining district during active mining. The Hessian Lignite Mining Museum still displays gypsum crystals in a variety of forms from Borken and the surrounding region. <\/p>\n

The crystals formed within clay-rich and sandy sediments of the lignite deposits. Gypsum occurred there as individual transparent crystals and as groups with tabular, prismatic, or fan-shaped habits. <\/p>\n

The former open-pit mine is now closed and is no longer accessible as a regular mineral locality. The combination of a double-terminated main crystal, fan-shaped accompanying crystals, and regional provenance makes this piece a characteristic specimen from the lignite mining history of northern Hesse. <\/p>\n
