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.The Mohs hardness scale definition of “scratch” is a permanent, visible defect (or “dislocation”). If a stone’s toughness (covered next) is more elastic and goes back to its original shape and appearance after, then that isn’t a scratch in Mohs scale terms. When Mineral A can scratch Mineral B, Mineral A will rank higher than Mineral B. Evaporite Minerals and Halides. ThoughtCo / Andrew Alden. Ulexite combines calcium, sodium, water molecules, and boron in a complicated arrangement with the formula NaCaB 5 O 6 (OH) 6 ∙5H 2 O. .
