chians after the Carboniferous and after a portion, at least, of the 

 Permian, and it may not have followed immediately after the 

 deposition of the Dunkard. 



The time of the Appalachian folding seems to have been also 

 an epoch of general epeirogenic movements. At this time much of 

 the eastern half and of the interior of North America was uplifted 

 and aqueous sedimentation largely stopped. Much of this region 

 was never again the site of notable sedimentation. 



In South America also a general movement of emergence seems 

 to have been in progress at this time. Katzer places the with- 

 drawal of the sea from the lower Amazon region within the Per- 

 mian. Schuchert states that the sea retreated from this region 

 "at the close of Neo-Carbonic time," and that thereafter the 

 interior of this extended land, as far as observations will permit 

 judging, was not again subjected to marine deposits.^ 



In Australia minor deformative movements are said to have 

 occurred in New South Wales during the Permo-Carboniferous 

 period, while Siissmilch states that at its close renewed orogenic 

 movements of a more pronounced sort took place in the same 

 region.^ At this time the folding extended sufficiently far south- 

 ward to develop a series of broad anticlinal and synclinal folds in 

 the Permo-Carboniferous strata along the northern edge of the 

 Maitland coal field where the folding is believed to have produced 

 an elevation of at least 7,000 to 8,000 feet.^ The axis of the folding 

 is north and south, parallel to the present coast. This was the last 

 folding in New South Wales; subsequent movements have been 

 of the epeirogenic sort. 



In eastern Europe it was not until late in the Permian that 

 folding is said to have taken place on the site of the Russian geo- 

 synclinal. All members of the Carboniferous, and some of the 

 Permian, thus form a thick concordant series. In the Donetz 

 basin, the Upper Permian was affected by the folding.''
