Contains polygon boundaries between mappable geologic units and polygon codes for the mappable geologic units. Arcs are coded to represent certainty of contact location. Annotation is added to indicate geologic units. Annotation size is scaled to plot as an 8 point Helvetica font when plotted at the indicated map scale. Contains mapped faults.
Arcs are codes to represent specific fault types and certainty of surface location.
Strike value rotates the point marker appropriately for the trend of the fault trace at the location of the point marker. Contains arcs representing fold axial traces. Arcs are coded to represent certainty of location of axial trace. Strike value rotates the point marker appropriately for the trend of the fold axial trace at the location of the point marker. For plunge direction, the strike is in the direction of axial plunge.
