Description: | Mineral hand specimen of Sphalerite associated with Limestone. Collected from Hydraulic Shaft, Smallcleugh Mine, Nenthead, Cumbria (NW England). Collected by Lindsay Greenbank, 1972 (c).
Sphalerite is also known as blende and black jack, and is an ore of zinc. Zinc is used as a raw material in the paint industry (zinc oxide is a white pigment), for galvanising iron, and in the manufacture of alloys, such as brass. Locally, sphalerite is common in the Nenthead area near Alston. It usually occurs as shiny black crystals.
The specimen was found in NW England. | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Greenbank Lindsay Classification: Sphalerite | Temporal: | Permian period (290 - 248 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
