helisummutite

Helisummutite is a rare mineral that was first discovered in the Khibina massif in Kola Peninsula, Russia. It is named after its chemical composition, which includes helium (He), summutite (a rare mineral itself), and other elements. The mineral is typically found in alkaline igneous rocks and is characterized by its unique crystal structure and optical properties.

Helisummutite is a member of the summutite group, which includes other rare minerals like summutite and khibinite. It is known for its distinctive yellowish-green color and its translucent to transparent nature. The mineral has a hardness of approximately 4.5 on the Mohs scale and a specific gravity of around 3.2.

The chemical formula of helisummutite is (Na,K)2Ca2(Fe,Mg)2Ti2Si8O24(OH)2. The presence of helium in the mineral is a notable feature, although it is not a significant component. The helium is believed to be a result of the mineral's formation process, which involves the interaction of various elements under high-temperature and high-pressure conditions.

Helisummutite is of interest to mineralogists and geologists due to its rarity and unique composition. It is also studied for its potential as a source of helium, although the extraction of helium from the mineral is not currently feasible due to its low concentration and the difficulty of processing the mineral.
