Graphic model > Elevation

The depths of the transition from one lithological layer to the next are recorded in this column. The values may be absolute or with signs. (See Depth scale).

All depth values in this column should of course be inferior to the starting value and will be negative if the origin value is zero or below.

If desired instead of entering a depth figure an interval (e.g. layer thickness) can be entered.

To switch between depth and thicknesses in this column, select the appropriate check box in the Options command (Preference menu).

The switch is dynamic so that the figures alter in response to the setting.
