Hematite xls; Wessels Mine, Kalahari Manganese Field, South Africa; TN; unique piece
Hematite crystals from the Wessels Mine, Kalahari Manganese Field, South Africa – micromount as unique piece
This micromount specimen with Hematite crystals from 1987 from the Wessels Mine, Kalahari Manganese Field, South Africa shows a single well developed crystal of this important iron oxide mineral. The crystal displays a deep black to steel gray color with a strong metallic luster and clearly defined, reflective crystal faces.
The Hematite crystal is freely developed and stands out clearly on the dark display base. The sharp crystal faces reflect light very well and give the specimen a particularly aesthetic appearance. Such isolated and well formed single crystals are especially attractive micromount pieces for collectors focusing on systematic mineral suites from the Kalahari Manganese Field.
Geology & Origin
The Wessels Mine in the Kalahari Manganese Field is one of the most important deposits worldwide for manganese rich mineralization and a large number of rare mineral species. The deposit formed in manganese rich sedimentary rocks of Proterozoic age that were later modified by metamorphic and hydrothermal processes. In addition to numerous manganese minerals, iron oxides such as Hematite can also occur and may form well developed crystals in this environment.
