Gleitums
Gleitums refers to a rare, hypothetical silicate mineral described in speculative geology and in some theoretical discussions of metamorphic petrology. The name is derived from the German gleiten, meaning to glide, chosen to reflect its proposed crystal habit with exceptionally smooth basal planes.
Gleitums crystals are typically colorless to pale blue, with a vitreous to pearly luster. It crystallizes in
It is described as forming under high-pressure, water-rich metamorphism in ultramafic rocks within subduction-zone environments, commonly
Gleitums has been discussed as a potential marker mineral for certain metamorphic conditions and as a theoretical
In literature, Gleitums is sometimes cited in debates about mineral classification and the interpretation of metamorphic
