A common rock-forming mineral found in felsic igneous rocks, pegmatites and metamorphic rocks, muscovite is the lightest-colored member of the mica mineral group. Micas are a group of sheet silicate minerals distinguished by their perfect single cleavage. This cleavage allows mica minerals to be easily split into thin parallel sheets.
Gypsum may seem like a miracle solution for soil, if what you need is a miracle.
