A’ A 22 Figure 2-2: Schematic cross-section A-A’ through the Scotian Basin showing seismic-stratigraphic sequences from Orpheus Basin through the Abenaki and Sable basins. Vertical exaggeration is 1:5. Various colours represent different mega-sequences that are predominately terrigenous clastics; green represents salt; pink is basement (modified from Welsink et. al., 1989). See Figure 2-1 for approximate location.
