kosteudenanturit

Kosteudenanturit is a hypothetical mineral name used in geology education to illustrate the properties of hydrated aluminosilicate minerals. It is not a recognized mineral in official catalogs such as the IMA Mineral Nomenclature, and it serves as a teaching example.

Etymology and naming: The term is a constructed name intended to evoke moisture retention, using roots associated with humidity and the common mineral suffix -urit; it has no endorsement as an actual mineral.

Physical and chemical properties: Kosteudenanturit is described as a translucent to opaque mineral with a pale blue-green color in fresh samples. It has a Mohs hardness around 4, a vitreous to pearly luster, and forms as microcrystalline aggregates. Its composition is described as a hydrous aluminosilicate with variable Fe and Mg; a general formula may be written as (Al,Fe,Mg)2Si4O10(OH)2·nH2O, with hydration level dependent on environmental conditions.

Occurrence and formation: In the hypothetical scenario, it forms by hydration of aluminosilicate precursors under moderate temperatures and high humidity, commonly in weathered crusts, hydrothermal zones, or near moist evaporitic margins.

Significance and uses: It is used in teaching to discuss hydration and mineral stability, porosity, and the influence of humidity on mineral structure. It does not have industrial use outside of didactic contexts.
