musklen
Musklen is a term used in some educational simulations and speculative fiction to denote a hypothetical mineral. It is not recognized as a real mineral by major geological authorities, including the International Mineralogical Association. In these contexts musklen is described as a silicate mineral that forms under high-temperature metamorphic conditions and occurs with other silicate minerals such as feldspar and mica. Descriptions vary, with musklen depicted as colorless to pale green and possessing a vitreous to pearly luster. Because musklen is not standardized, there is no universally accepted chemical formula or set of physical constants for it.
The use of musklen in teaching materials aims to illustrate mineral classification, crystallography, and metamorphic processes
