angle of dip

• Angle qu'une couche rocheuse ou une surface géologique forme avec le plan horizontal, mesuré perpendiculairement à la direction (strike). Il indique l'inclinaison maximale de la couche.

The angle that a rock layer or geological surface makes with the horizontal plane, measured perpendicular to the strike. It indicates the steepest slope of the layer.

1. Geomagnetic inclinationC2formal

   The angle that the Earth's magnetic field lines make with the horizontal plane at a given location.

   • The angle of dip is measured using a dip circle.
   • At the magnetic equator, the angle of dip is zero degrees.
   • Geologists use the angle of dip to study the Earth's magnetic history.
