Figure 2.8
Measurement of the dip direction and dip magnitude of a plane with the Brunton Geo compass-
clinometer in one position. (a) Side view of the compass-clinometer in position for measuring both the dip
magnitude and dip azimuth. (b) Close up view of the hinge area. The dip magnitude is read off where the top
of cut-out intersects with the scale; in this case it is 12°. Note also the extra spirit level on the side indicating that
the compass window is horizontal. (c) View of the compass window showing that the compass window is level
(round spirit level) and that the dip azimuth is 098°. This bedding plane is thus orientated at 008/12E.
