cellasiteokite
cellasiteokite is a mineral belonging to the silicate group. It is a rare, hydrated magnesium iron silicate. Its chemical formula is typically given as Mg4(Mg2Fe3+)(Si6O18)(OH)2·2H2O. cellasiteokite was first discovered in the Eastern Sayan Mountains of Siberia, Russia, and was named after the locality. It is often found in metamorphic rocks, particularly those rich in magnesium and silica. The mineral typically appears as fibrous or radiating aggregates, and its color can range from white to pale green or gray. In terms of physical properties, cellasiteokite is relatively soft, with a Mohs hardness of around 4.5. It is also a moderately dense mineral. Crystallographically, it is monoclinic. Its formation is associated with low to medium-grade metamorphism of serpentinites and other ultramafic rocks. Due to its rarity, cellasiteokite is not of significant commercial importance, but it is of interest to mineralogists for its unique chemical composition and geological context.
