Kornerupine, also known as prismatine, is a rare mineral with a fascinating history and unique properties. Here's a detailed overview of its history, naming, occurrence, and its close relatives:
Kornerupine was first discovered in Greenland in 1884 by the Danish geologist, Andreas Nikolaus Kornerup, who the mineral is named after. However, it wasn't until 1887 that it was formally described and identified as a new mineral species by the mineralogist, George F. Kunz, and the chemist, Washington A. Roebling. Since its initial discovery, kornerupine has been found in a few other locations around the world, but its occurrence remains relatively limited.
As mentioned earlier, kornerupine was named after its discoverer, Andreas Nikolaus Kornerup, as a way to honor his contributions to geology and mineralogy. The naming of minerals after their discoverers or important figures in the field is a common tradition in the world of mineralogy.
Kornerupine is a rare mineral and is typically found in metamorphic rocks. It forms under high-pressure and high-temperature conditions, often as a result of the regional metamorphism of magnesium-rich rocks. The mineral is commonly associated with other minerals such as garnet, sillimanite, kyanite, and staurolite in the formation of schists and gneisses.
Apart from its initial discovery in Greenland, kornerupine has been found in other locations around the world, although occurrences are relatively scarce. Some notable locations include:
3. Sri Lanka
4. Myanmar (Burma)
However, it's important to note that these locations may not always yield significant quantities of kornerupine, and the mineral is often found in small, rare occurrences.
Kornerupine is a member of the borosilicate mineral group, which includes various minerals that share some similar characteristics. Some of its close relatives include:
1. **Axinite:** Axinite is a calcium aluminum borosilicate mineral that often occurs in hydrothermal veins associated with volcanic activity. It is known for its complex crystal structures and various color varieties, including brown, green, blue, and purple.
2. **Dumortierite:** Dumortierite is an aluminum borosilicate mineral that is commonly found in metamorphic rocks. It is prized for its intense blue color and is often used as a decorative stone and in jewelry.
3. **Vesuvianite:** Also known as idocrase, vesuvianite is a calcium aluminum silicate borate mineral. It is found in contact metamorphic rocks and can display various colors, including green, brown, yellow, and blue.
4. **Datolite:** Datolite is a calcium borosilicate mineral that forms in hydrothermal veins and basalt cavities. It is typically found in colors ranging from colorless to white, yellow, and green.
These minerals share some structural and compositional similarities with kornerupine due to their borosilicate nature, but each of them possesses unique properties and characteristics that make them distinct from one another.
In conclusion, kornerupine is a rare and fascinating mineral that was discovered in Greenland and named after the Danish geologist Andreas Nikolaus Kornerup. It occurs in metamorphic rocks and is associated with other minerals like garnet and kyanite. Although it can be found in several locations worldwide, its occurrences are generally limited. As a member of the borosilicate mineral group, it has close relatives such as axinite, dumortierite, vesuvianite, and datolite.
Kornerupine has been mined in Tanzania, particularly in the Kizara Forest in Tanga Province. In this region, kornerupine is found in metamorphic rocks associated with the Mozambique Belt, which is a geological formation known for hosting various gemstones and minerals. The gem-quality kornerupine found in Tanzania is typically green to blue/purple in color and is highly valued by collectors and gem enthusiasts for its rarity and unique characteristics.
However, it's important to note that mining activities and locations may change over time, and new deposits might be discovered. Therefore, for the most up-to-date information on kornerupine mining in Tanzania, please stay tuned in to our website updates.
