Metamorphic rocks
Metamorphic rocks are formed by the transformation of other rocks (igneous, sedimentary or metamorphic) due to high pressure and/or temperature, without melting.
Features:
Foliated texture: Minerals organized in layers (e.g.: gneiss, schist).
Non-foliated texture: No layers, solid appearance (e.g. marble, quartzite).
Examples:
Marble: Originates from limestone.
Quartzite: Derived from sandstone.
Gneiss: Comes from granite.
Shale: Results from mudstones/metapelites.
These rocks are widely used in construction and decoration.
