Slate Slate Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates
Stage name more ethnic identity, when that gave them an advantage in playing "ethnic" roles. An example of this type of name change was Freddie Mercury of the British rock band Queen, who was born Farrokh Bulsara to Parsi parents; his name change was partly intended to conceal his heritage. Italian-American actress Bernadette Peters, who was born Bernadette Lazzara, changed her last name to avoid being typecast as women who were Italian or of Italian heritage. Likewise, heavy metalist Ronnie James Dio, also of Italian descent, changed his name from Ronald James Padavona, after the mobster, Johnny Dio (whose name was also
