Zones and Zone Symbols. A zone is defined as a group of crystal faces that intersect in parallel edges. Since the edges will all be parallel to a line, we can define that the direction of the line using a notation similar to Miller Indices. This notation is called the zone symbol. The zone symbol looks like a Miller Index, but is enclosed in ...Labeling strike and dip. Geologic maps that display strike and dip symbols require the label to be rotated with the symbol. Use the Maplex Label Engine Additional Rotation option to rotate the label to match the rotation of the dip symbol.. In the image below, the dip label has been rotated an additional 90 degrees to line up with the symbol and has been …
