2. Background
A number of researchers have addressed the topics of tectonic stability
and paleo sea level using data gathered fromtheMIS 5e features preserved
in the Cape Region (e.g., Denman and van de Graaff, 1977;
Kendrick et al., 1991; O'Leary et al., 2008a). The products of these investigations
are two contrasting sets of literature: the first recognizes late
Quaternary tectonic deformation in the region; while the second
considerswestern Australia as tectonically stable and thereby providing
a paleo sea-level datum.
