Muscovite schist is a relatively soft rock 🪨, with a Mohs hardness of 2.5 to 3. It is also a relatively weak rock, and it is not very resistant to weathering.

The Greenschist is formed into metamorphic rock formed at the lowest temperature of 350˚C, and a pressure of 4-kilo bars, producing regional metamorphism, with abundant green minerals like Muscovite ...
