Comment:
What does adjacency in the map legend mean? Assume that map legend is organized purely chronologically, ignoring cases where ages of units are unknown or have wide ranges. Also assume that GIS software is capable of a 'select inverse' operation. Resolution of this query would require a procedure to step through the legend using the ordering attribute that structures the chronological order of  the map units, and select all lines that separate adjacent map units, and making a union of newly selected lines with already selected lines to form the set of all lines that separate units adjacent in the legend, then selecting the inverse of this set.

A scarp would be a line feature; dip determinations would be associated with point features, and by definition these better not have been measured where there are slope movement scarps, so this query requires some algorithm for determining the region of influence for individual bedding measurements with the strata are not homoclinal. If unit is homoclinal, query searches for intersections of scarps (linear features) with polygons (Reedsville Shale outcrop where dip >25). If the bedding  dip  variable, have to determine polygons within which dip is expected to be >25, and intersect these with scarps.
