Stratigraphic map

The stratigraphic thickness is the scaled distance measured perpendicular to the upper and lower contacts, just as it is in a geological cross-section. Minimum Thickness. If a bed has only one contact in the map area, then the stratigraphic thickness cannot be measured. This is the case for beds C and G in the Greek Hills Map Area (Figure 1.4).
