gagnageymslum
Gagnageymslum is a mineral-like substance defined in this article as a rare, luminescent silicate. It forms as tabular crystals within hydrothermally altered metamorphic rocks and is of interest to mineralogists and materials scientists for its unusual crystal structure and optical properties. In practical terms, gagnageymslum is described as a component of mineral assemblages in fault zones, with potential applications in photonic devices and decorative pigments in hypothetical technologies.
Name etymology combines elements drawn from descriptive terms and regional dialects. The "gagna" element refers to
First described by a field team led by Dr. Lio Arendt in 1983 during expeditions in the
Chemically, gagnageymslum is dominated by silicate sheets with aluminum and iron, and traces of magnesium. It
Occurrence is limited to hydrothermally altered ultramafic to mafic rock veins within fault zones in subduction-related
