Figure 11. Extension versus age diagram showing the incremental elongation of the 10 cross sections (see locations in Figure 1). The box represents the 25%–75% percentile, and the whiskers represent the minimum and maximum extent. During Late Cretaceous (top Waarre Formation [Fm.] and top Skull Creek Mudstone [Mst.]), the cross sections show median values of 7%–10% extension, but there is a very wide range (see text for details). The deformation activity dies out rapidly after Timboon Sandstone (Sst.) deposition. In all 10 cross sections, 99% of extension occurred before deposition of top Timboon Sst. (66 Ma). After 66 Ma, the elongation was almost only 1%, that is, most faults had died out by this time. Gr. = Group; Mst. = Mudstone.
