pinnoiteaineilla

Pinnoiteaineilla, also known as pinnoite, is a rare mineral discovered in 1987. It is named after the Finnish word "pinnoite," which refers to a type of rock found in the area where the mineral was first discovered. Pinnoiteaineilla is a complex oxide mineral with the chemical formula (Na,Ca)2(Fe,Mn)2Ti2O8. It crystallizes in the cubic crystal system and typically forms small, dark brown to black crystals or granular masses.

Pinnoiteaineilla is primarily found in alkaline igneous rocks, such as nepheline syenites and carbonatites, in areas with a high concentration of sodium and calcium. It is often associated with other minerals like aegirine, arfvedsonite, and sodalite. The mineral's discovery was significant because it provided new insights into the geological processes involved in the formation of alkaline igneous rocks.

Pinnoiteaineilla has no known practical applications due to its rarity and the difficulty in extracting it from its host rocks. However, it is of interest to mineralogists and geologists studying the complex chemistry and mineralogy of alkaline igneous rocks. The mineral's unique composition and crystal structure make it a valuable subject for scientific research.
