Figure 16. Two-dimensional cross sections of the retrodeformed Skull Creek Mudstone (Mst.) and Timboon Sandstone (Sst.) with their respective strain distributions and interpretations (for location of cross section, see Figure 13D). The 
strain magnitude, where e is the strain value and 
is the principal major strain axis, is color-coded. (A) Timboon Sst.: the 
strain magnitude is close to zero, except for the southernmost tip. (B) Sketch showing the amount of subseismic scale fracturing is minimal. (C) Skull Creek Mst.: the 
strain magnitudes are higher in the southwestern and central parts. (D) Sketch showing the relative distribution of the subseismic scale faults in the Skull Creek Mst. Areas with patches of higher strain magnitudes (violet). These areas are potential pathways for fluid or gas migration, but subseismic scale fractures of the underlain Skull Creek Mst. do not continue into the Timboon Sst. above.
