Strike, or [[azimuth]], is the orientation of a body or surface, measured where it intersects a horizontal plane. It is perpendicular to true [[dip]]. Strike is usually written as N25E, to distinguish it from dip, which is written 4S, 4SE, or 4 65SE. | Strike, or [[azimuth]], is the orientation of a body or surface, measured where it intersects a horizontal plane.
