Obviously, conclusions can only be tentative, as data are 

 sadly wanting in regard to trend lines. Present-day mountain 

 ranges not infrequently, as in the case of the Victorian Alps, 

 do not correspond to the directions of folding. Certain pro- 

 positions are, however, advanced in this paper for further 

 investigation. Certain queries of world-wide geological interest 

 arise. 



Why are tropical regions essentially plateaux and sub- 

 merged plateaux regions ? Were equatorial regions in Archseo- 

 zoic times dominantly continental ? Was there a strong rock 

 flowage in the upper earth's crust giving rise to west-north-west 

 trends in southern latitudes and west-south-west trends in 

 northern ? 



Other matters touched on, as, for instance, the questions 

 of lodes and mineral resources, are more purely of Australian 

 interest. 



The questions raised are not for one geologist to solve. 

 'They require the collaboration of all.
