Raamistandardite

Raamistandardite is a rare mineral species discovered in 2014. It is named after the Raamis mine in the Khibiny Massif, Kola Peninsula, Russia, where it was first found. The mineral is characterized by its unique chemical composition and crystal structure. Raamistandardite is a sodium-calcium-titanium silicate with the chemical formula NaCa2Ti2(Si6O18). It crystallizes in the monoclinic system and typically forms small, prismatic crystals or granular aggregates.

The mineral exhibits a pale yellow to colorless appearance and has a vitreous luster. Its hardness on the Mohs scale is approximately 5.5, and it has a specific gravity of around 3.2. Raamistandardite is often found in association with other minerals such as aegirine, microcline, and eudialyte in alkaline igneous rocks.

Raamistandardite's discovery and characterization have contributed to the understanding of the complex mineralogy of the Khibiny Massif and the broader region of the Kola Peninsula. Its rarity and unique properties make it of interest to mineralogists and collectors alike. Further research is ongoing to fully understand its geological context and potential economic applications.
