sericite

In mineralogy terms the difference between sericite and muscovite

is that sericite is a fine-grained mica found in metamorphic rocks while muscovite is a pale brown mineral of the mica group, being a basic potassium aluminosilicate with the chemical formula KAl₂(Si₃Al)O₁₀(OH,F)₂; used as an electrical insulator etc.

As an adjective Muscovite is

of or relating to Muscovy or Moscow, or the people of these places.
