Laviidusel

Laviidusel is a relatively rare and lesser-known mineral species, first identified in the early 20th century. It is a type of borate mineral, classified as a member of the rhomboclase group. The name "laviidusel" comes from the Latin word "lavius," meaning "from Lavieu," which is a small town in France where the mineral was initially discovered.

Laviidusel has a chemical composition of Ca3B5O9(OH)5·7H2O and crystallizes in the hexagonal system. Its formula indicates the presence of boron, calcium, and water within its crystal structure. The mineral typically exhibits a range of hues, including shades of yellow, orange, and brown, often with a waxy or resinous appearance.

From a geological perspective, laviidusel is often found in association with other borate minerals, which are typically deposited in areas where water has a high concentration of boron. The mineral is also known to form in evaporite environments, such as salt lakes and dry playas. While it has been identified in a few locations worldwide, its distribution remains relatively limited.

In terms of its rarity, laviidusel is generally considered a somewhat rare mineral, especially when compared to other borate minerals. However, its relative difficulty in identification and the limited scope of research on the mineral mean that more information is likely to remain a subject of scientific investigation.
