haigusseisundite
Haigusseisundite is a rare silicate mineral described from hydrothermal veins in the Haigusseis region. The mineral is characterized by an iron- and aluminum-rich composition within a hydrated silicate framework and is notable for its occurrence in high-temperature hydrothermal environments.
The name Haigusseisundite derives from the locality Haigusseis and follows the traditional mineral-naming practice of adding
Haigusseisundite exhibits a silicate framework with hydroxyl groups. The composition is dominated by iron and aluminum,
The mineral tends to form prismatic to tabular crystals and aggregates. Color ranges from dark gray to
Haigusseisundite forms in high-temperature hydrothermal veins cutting silica-rich host rocks. It is commonly associated with quartz,
As a recently described and locally restricted mineral, Haigusseisundite is of interest for mineralogical taxonomy and
