Slate is a low-grade metamorphic rock composed of extremely fine mica and other mineral grains. It typically exhibits well-developed rock cleavage, which is a planar fabric that allows the rock to split into thin sheets or slabs. The alignment of the mica and other minerals along this cleavage plane gives slate its characteristic foliated texture.
