Slate is a fine-grained, metamorphic rock composed of quartz, muscovite,
graphite and other minerals. Slate is actually formed from shale that
has low heat and not very much pressure applied to it. It is mainly
found in mountain areas, and is quarried in Pennsylvania, Georgia,
Vermont, New York and throughout the world in such places as Brazil,
France, Germany, Italy, North Wales, Newfoundland, Portugal, China and
the Arctic. Slate is usually found in various shades of gray or black
but can also be found in a variety of colors such as purple, green,
blue and cyan. Slate tiles are often used for interior and exterior
flooring, stairs, walkways and wall claddings.
