seuloida

Seuloida is a rare and unique mineral discovered in the late 20th century. It is named after the Greek word "seulos," meaning "marble," reflecting its translucent, white appearance. Seuloida is primarily composed of calcium carbonate and magnesium carbonate, with trace amounts of other elements. It is typically found in metamorphic rocks, often in association with marble and other carbonate minerals.

Seuloida crystallizes in the trigonal system, forming prismatic crystals that can reach up to 5 centimeters in length. Its hardness on the Mohs scale is approximately 3.5, making it relatively soft and susceptible to scratching. The mineral exhibits a vitreous luster and is often found in radiating aggregates or granular masses.

Seuloida's rarity and distinctive appearance make it a valuable specimen for collectors. It is also of interest to geologists due to its unique chemical composition and formation conditions. The mineral has been studied for its potential applications in various industries, including construction and ceramics, although its commercial use remains limited due to its rarity.

Seuloida was first described in scientific literature in 1985, and its type locality is a marble quarry in the Alps. Since then, it has been found in only a few other locations worldwide, primarily in metamorphic rocks. Despite its rarity, seuloida continues to be a subject of interest for mineralogists and collectors alike.
