earvetite

Earvetite is a rare mineral discovered in 2010 within the Khibina alkaline complex in the Kola Peninsula, Russia. It is named after the Russian mineralogist, Evgeny V. Sidorov, who first identified and described the mineral. Earvetite is characterized by its unique chemical composition, which includes the elements sodium, calcium, titanium, and silicon, along with oxygen and hydrogen. Its crystal structure is monoclinic, and it typically forms small, prismatic crystals.

The mineral is notable for its distinctive color, which ranges from pale yellow to brown, and its translucent to transparent nature. Earvetite is often found in association with other minerals such as aegirine, arfvedsonite, and eudialyte, indicating its formation in complex, alkaline igneous rocks. Its discovery has contributed to the understanding of mineral formation in alkaline environments and has sparked interest among mineralogists and geologists studying the geochemistry of rare minerals.

Earvetite's rarity and unique properties make it a subject of interest for collectors and researchers alike. Despite its limited occurrence, the mineral serves as a valuable specimen for scientific study and exhibits its significance in the field of mineralogy.
