Slate

Slate is defined as a fine grained, metamorphic rock exhibiting slaty “cleavage” which allows it to be split into thin sheets.  It is a low grade metamorphic rock formed from shale, which is a thin-bedded, fine grained; clastic sedimentary rock compacted from mud of clay sized silicate clay minerals.  Slate is often found in suspended turbid waters of rivers, lakes, and ponds following heavy rains. Slate on the Mohls Scale has a hardness rating between H=2.5 and H=4.

Slate is an excellent choice for fireplace surrounds, flooring, and is often used for exterior pavers and wall cladding.  Slate offers a very natural rustic look.
