specimen number:

location:
Oruro, Bolivia

description:
Said to have been collected around the year 1850, needlelike metallic crystals of stibnite across matrix with pyrite. The specimen comes with an antique label as shown at the end of the video. Neat example for this area.

Oruro, Bolivia, is part of a major mining region in the central Andes with a long history of mineral extraction dating back to the Spanish colonial period. The district is characterized by hydrothermal vein deposits associated with volcanic activity, where mineralizing fluids introduced tin, silver, and other metals into fractures within volcanic and sedimentary rocks. Mining expanded significantly in the 19th and early 20th centuries, with tin becoming the dominant commodity and helping to establish Bolivia as a leading tin producer. The geology of the area includes complex vein systems and breccia zones enriched in cassiterite and various sulfide minerals. Oruro remains an important historic mining center, known for both its economic contributions and its diverse mineralization.
