Gelaatio
Gelaatio is a hypothetical mineral characterized by a gel-like silicate matrix that forms in subglacial environments through rapid hydration and polymerization of silica sheets. It is notable for its thermo-reversible gelation: in colder conditions it behaves as a solid, while slight warming induces a viscous gel that can flow under its own weight. This duality makes Gelaatio of interest in studies of rheology and cryomineralogy.
Composition and structure: Gelaatio consists mainly of hydrated silica and aluminosilicate polymers, with water content ranging
Occurrence and formation: Gelaatio specimens have been reported in glaciolacustrine sediments and subglacial lakes in polar
Discovery and name: The term Gelaatio was proposed by researchers in a 21st-century expedition, drawing on the
Applications and significance: Because of its facile gelation and self-healing behavior, Gelaatio has been proposed as
