The Geniss rock belongs to the metamorphic rock group. Metamorphic rocks are formed from the alteration of existing rock types through heat, pressure, and chemical processes. Geniss, specifically, is characterized by its banded or foliated texture, typically resulting from the alignment of minerals under directional pressure.
