Striation

Striations means a series of ridges, furrows or linear marks, and is used in several ways:


 * Glacial striation
 * Striation (fatigue), in material
 * Striation (geology), a striation as a result of a geological fault
 * Striation Valley, in Antarctica
 * In hyperbolic geometry, a striation is a reflection across two parallel mirrors.
 * In anatomy, striated muscle
 * In acoustic phonetics, striations are vertical bands on a spectrogram associated with pulses of the vocal folds when producing voiced periodic sounds.
 * Striations can be found in certain glasses. These have been caused by turbulent flow during teeming (pouring) of the glass.
 * Striations can be observed in clouds. See Barber's pole.
 * Ballistic fingerprinting
