Endoteelipinnoite
Endoteelipinnoite is a rare silicate mineral described in mineralogical literature. It is associated with high-temperature hydrothermal systems and ultramafic rocks. The mineral occurs as prismatic to fibrous crystals and is typically found in small, disseminated grains within altered serpentinite.
Composition and structure: The composition is dominated by calcium and silicon with iron and magnesium as minor
Physical properties: Endoteelipinnoite has a vitreous to pearly luster, a white to pale gray color, and a
Occurrence and formation: Type locality is in a metasomatic zone of ultramafic rocks where high-temperature fluids
Etymology and significance: The name Endoteelipinnoite combines the prefix endo- ('within') with a coined element name;
