Olivenite
specimen number:
2354242
location:
Majuba Hill Mine, Pershing Co., Nevada, USA
description: The geology of the Majuba Hill Mine in Pershing County, Nevada, is characterized by a complex Tertiary volcanic center consisting of a rhyolite plug and associated breccia masses that intruded older sedimentary rocks, featuring intense hydrothermal alteration, tourmalinization, and multi-stage metal deposition. Historically, the mine operated during distinct periods of underground exploration and production, initially yielding high-grade copper ore during World War I and later experiencing a reactivation to mine tin alongside valuable amounts of silver, gold, and secondary metal minerals.
Olive green sparkling needlelike crystals of olivenite to 0.3 cm in length scattered across the front side of matrix. In good condition.
Size: 6.0 x 4.6 x 3.6 cm (small-cabinet)
