Magnetic Inclination

(or magnetic dip), the angle I between the intensity vector T of the geomagnetic field and the horizontal plane at a given point on the earth’s surface. The magnetic inclination is measured upward and downward from the horizontal plane. It is positive when T is directed downward from the horizontal plane, which is the case in the northern hemisphere, and it is negative when T is directed upward, as in the southern hemisphere. The magnetic inclination varies over the earth’s surface from 0° to ±90”. Curves connecting points on the earth’s surface having the same magnetic inclination are called isoclinic lines. The isoclinic line I = 0° is called the magnetic equator. The point at which I = 90° is the north magnetic pole of the earth, and the point at which I = —90° is the south magnetic pole. The magnetic inclination is measured with an inclinometer.

magnetic inclination

The same as magnetic dip.

The samples were not oriented in azimuth but bedding planes were prominent allowing magnetic inclinations to be determined before and after a tilt correction.

However, we can determine magnetic inclinations with respect to bedding planes.
