and covered with the marine beds, it appears quite probable that this was 

 so. The physiographical evidence is consistent with the supposition that 

 a regional or very slightly difierential elevation preceded tlie main Kai- 

 koura deformation, and from the coastal plain thus formed the overlying 

 soft mudstones and sandstones might be largely stripped by subaerial 

 erosion before the involvement of the Notocene along the great Clarence 

 and other faults. In any case, it could only be })y a favourable sequence 

 of events that such beds, if involved, could be preserved during the sub- 

 sequent erosion that lias occurred. If they had been so involved and 

 subsecpicntly eroded, there would be at lirst a fault-line scarp fornied. 

 and the steep scarps south-westward from the Dee may be, in part, of this 

 nature.
