BILIBINSKITE Meaning and
Definition
-
Bilibinskite is a rare mineral that belongs to the phosphate mineral group. It was first discovered in the Bilibinskoye deposit in Chukotka Autonomous Okrug, Russia, which is where its name originates. Bilibinskite is classified as a hydrated calcium uranyl phosphate mineral, with the chemical formula Ca(UO2)3(PO4)2(OH)4·6H2O.
This mineral crystallizes in the tetragonal system, forming yellow to greenish-brown tabular or prismatic crystals. It has a vitreous to greasy luster and is translucent to transparent. Bilibinskite has a relatively low hardness on the Mohs scale, typically ranging from 2.5 to 3.5. It also exhibits fluorescence under ultraviolet light, appearing bright yellow to pale green.
In terms of its composition, bilibinskite contains calcium, uranium, phosphorus, oxygen, and hydrogen. It is formed through the oxidation of primary uranium minerals, mainly uraninite, under oxidizing conditions. Bilibinskite is commonly found in association with other secondary uranium minerals, such as phosphuranylite and dewindtite.
Due to its rarity and limited occurrence, bilibinskite holds little economic significance. Instead, it primarily serves as a mineral of interest for collectors and researchers in the field of mineralogy and uranium mineralogy. Its distinctive crystal structure and unique composition make it an intriguing mineral for scientific study and investigation.
Etymology of BILIBINSKITE
The word "bilibinskite" derives its name from the Bilibino district, specifically from the town of Bilibino in Chukotka Autonomous Okrug, Russia. Bilibinskite is a mineral that was discovered in this region. The suffix "-skite" is often used in mineral names to indicate the type of minerals or the location where they were found.
