Slate is a fine-grained, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low grade regional metamorphism. The result is a foliated rock in which the foliation may not correspond to the original sedimentary layering.

Wow, I don't think you were asking about the type of rock slate is. The origin of the name "Slate" ,the news blog, is that in ancient times, news used to be chiseled into slate, the rock. FYI.
