otheruses Slate is a fine-grained, homogeneous, sedimentary rock composed of clay or volcanovolcanic ash (volcanic)ash which has been metamorphic rockmetamorphosed (foliated) in layers (bedded deposits). Slate can be made into roofing slates (sometimes called 'roofing shingles' in the United States), because it has two lines of breakability: cleavage and grain. This makes it possible to split slate into thin sheets. Fine slate can also be used to hone knives.Slate is mainly composed of quartz and muscovite (a mica), often along with biotite, chlorite, and hematite, or, less frequently, apatite, graphite, kaolin, magnetite, tourmaline, or zircon.Some of the finest slates in the world come from Portugal, Wales in the United Kingdom, the east coast of Newfoundland, and the "Slate Valley" of Vermont and New York.
