Siderite on Barite with Stibnite

specimen number:
2312400

location:
Baia Sprie, Maramures Co., Romania

description:
Bladed crystals of barite measuring to almost 3.0 cm in size mostly coated by botryoidal crystallized siderite. Sprays of metallic stibnite are scattered throughout. In very good condition, classic material for this locality in the 1970s.

Baia Sprie, historically known by the Hungarian name Felsobanya, was first officially documented in 1329 and developed into a major medieval mining center for gold, silver, and base metals under Hungarian and Habsburg administration. Large-scale underground and surface mining operations continued for centuries until the active commercial exploitation of its metal deposits ceased in 2007. Geologically, the area is situated within the Neogene volcanic chain of the Gutai Mountains in the Baia Mare metallogenic district. The local geology is characterized by complex Neogene volcanic structures cutting through sedimentary and metamorphic basement rocks, hosting world-renowned hydrothermal vein systems rich in diverse polymetallic sulfide and precious metal mineral assemblages.
