Feinglosite is a rare mineral that belongs to the carbonate mineral group. It is composed mainly of calcium, carbon, and oxygen, with the chemical formula Ca2(BH4)(CO3)2. It was first discovered in the late 1980s in the Franklin mine, New Jersey, where it was named after its discoverer, Dr. Michael S. Feinglos, a renowned American mineralogist.
Feinglosite typically occurs as small, tabular or platy crystals, often with a pale pink, colorless, or white appearance. It has a vitreous to pearly luster, and its hardness is relatively low, ranking around 2-3 on the Mohs scale. This mineral is known for its distinctive association with other rare minerals, such as hanksite, colemanite, and boracite.
As a relatively rare mineral, feinglosite often attracts the attention of mineral collectors and researchers due to its unique crystal structure and composition. It is considered to be of scientific interest because of its potential applications in the field of material science. However, due to its scarcity, it has no significant economic value or industrial use. Nevertheless, feinglosite continues to be studied and analyzed to gain a deeper understanding of its crystallography and its occurrence in various geological formations.
In summary, feinglosite is a rare calcium carbonate mineral that forms small, tabular crystals. Its name originates from its discoverer, Dr. Michael S. Feinglos, and it is notable for its association with other rare minerals. While it lacks economic value, it remains a subject of study for its unique structure and potential scientific applications.
