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
Name change Generally the judge has limited judicial discretion to grant or deny a change of name, usually only if the name change is for fraudulent, frivolous or immoral purposes. In 2004, a Missouri man succeeded in changing his name to They. The Minnesota Supreme Court ruled that a name change to 1069 could be denied, but that Ten Sixty-Nine was acceptable ("Application of Dengler", 1979); the North Dakota Supreme Court had denied the same request several years before ("Petition of Dengler", 1976). In nearly all states, a person cannot choose a name that is intended to mislead (such as adopting a
