Lüsiini

Lüsiini is a rare mineral composed primarily of calcium and silicate. Its chemical formula is Ca8(Si6O18)2(OH)2·4H2O. Lüsiini typically forms in metamorphic rocks under conditions of high temperature and pressure. It is often found in association with other silicate minerals such as garnet, pyroxene, and amphibole. The crystals of lüsiini are usually small and prismatic, exhibiting a vitreous luster. The color of lüsiini can range from white to light gray, and it is generally translucent. Its hardness on the Mohs scale is around 5 to 5.5, indicating a moderate resistance to scratching.

The discovery of lüsiini is attributed to researchers in the early 20th century, though specific details regarding its initial identification and naming are not widely documented. It is considered a mineral of scientific interest due to its unique crystal structure and chemical composition, which provide insights into geological processes. Lüsiini is not a commercially significant mineral and is primarily collected by mineral enthusiasts and researchers for its rarity and mineralogical properties. Its occurrence is geographically limited to a few specific locations worldwide, often found in metamorphosed carbonate sequences. Further research is ongoing to fully understand its formation mechanisms and potential geological significance.
