Dimereit

Dimereit is a fictional mineral described for use in educational and encyclopedic contexts. This article presents a concise, neutral account of the mineral as it is commonly depicted in geoscience teaching materials, with caveats that it is not a real mineral recognized by major catalogues.

Description and composition: Dimereit is described as a hydrated aluminosilicate with a layered framework. In standard fictional accounts its general formula is written as (Ca,Na)2(Mg,Fe)3Al2Si6O20(OH)4·nH2O, reflecting variable cation occupancy and water content. Crystallography is said to be monoclinic with sheet-like silicate layers.

Crystal structure and properties: Crystals are described as tabular to prismatic, often attaining several millimeters in length. It is attributed a Mohs hardness of about 4–5 and a vitreous to pearly luster. Color is typically pale green to gray.

Occurrence and discovery: Dimereit is imagined to occur in hydrothermally altered volcanic rocks and in sedimentary basins with significant diagenetic hydration. The fictional type locality is the Xenolith Formation in the imaginary region of Xyla.

Nomenclature and status: The name is constructed for illustrative purposes, drawing on a binary-sound motif. In this fictional context, Dimereit is not listed in real mineral databases and has no established industrial use.
