Coffinite: The Eerie Mineral with a Macabre Name
Coffinite, with its name evoking images of the macabre, is a mineral that holds great interest for geologists and mineral collectors alike. This rare mineral, named after the French mineralogist Octavie Auguste Coffinier, was discovered in the Democratic Republic of Congo in 1892. Classified as an uranium mineral, coffinite's chemical composition is closely related to uraninite, with the formula U(SiO3)2(OH)2. Its unique crystal structure belongs to the tetragonal crystal system, which gives coffinite its distinctive geometric appearance.
Coffinite is most commonly found in the form of small, prismatic crystals that display a variety of colors, ranging from yellow to brown, red, or even black. These crystals often exhibit a striated or banded appearance, adding to the mineral's visual appeal. The mineral's hardness, ranging from 5.5 to 6 on the Mohs scale, and its specific gravity of approximately 5.5 make it relatively durable and resistant to weathering.
One of the most intriguing aspects of coffinite is its association with uranium deposits. As a uranium
