Manhattan schist

Exhibition Text

Originally a shale, this schist now consists of dark, biotite-rich layers and finer-grained, light-colored layers made of gray quartz and white orthoclase. The distinct layering developed perpendicular to the direction of compression. This schist underlies most of Manhattan.
