radiolaite

Radiolaite is a rare mineral composed primarily of calcium, aluminum, silicon, and oxygen, with the chemical formula Ca12Al14O32(SO4)2. It is a member of the nosean group of minerals, which are characterized by their cubic crystal system. Radiolaite was first discovered in the Eifel region of Germany and is named after its type locality, the Radiola quarry.

The mineral typically occurs as small, euhedral crystals, often transparent to translucent and white to pale yellow in color. It is known for its distinctive optical properties, including a high refractive index and birefringence. Radiolaite is often found in association with other minerals such as melilite, vesuvianite, and perovskite, usually within volcanic rocks.

Due to its rarity and the limited number of known occurrences, radiolaite is not of significant economic importance. However, it is of interest to mineralogists and geologists for its unique chemical composition and crystallographic properties. The study of radiolaite contributes to our understanding of the formation and evolution of certain types of igneous rocks. Further research continues to explore its precise geological context and potential for new discoveries.
