EXPLANATION OF PLATE 



In Plate VI is given a drawing showing the reconstructed 

 section and the depths of the deformed zone based on dimensions 

 obtained from the two sections (see text). In order to make the 

 horizons of the Greta Coal Measures and the Muree beds clearly 

 seen on the small scale, in which the section is necessarily drawn, 

 these two series have been exaggerated at the expense of the 

 Branxton Beds and the Crinoidal Shales respectively. A uniform 

 thickness of Kuttung rocks is shown beneath the Permo-Car- 

 boniferous series, but no particular horizon in the former series is 

 intended to be represented. The whole of the Upper Coal Measures> 

 that is all strata above the Upper Marines, have been considered 

 collectively, and thus are coalesced in the section. In the draw- 

 ing of the earth blocks under each section portion, dotted lines 

 have been used to represent those blocks whose dimensions were 

 obtained from the original section, and full lines for the blocks 

 whose dimensions resulted from a consideration of the amended 

 section.
