It will be seen that the Carboniferous System has a 

 probable maximum thickness of at least 14000 feet, while 

 the succeeding Permo-Carboniferous System has a thick- 

 ness of at least 16000 feet, giving a total thickness of Upper 

 Palaeozoic strata in this part of N. S. Wales of not less 

 than 30000 feet. 



The whole of the Carboniferous formation has been folded 

 into a series of broad anticlines and synclines, which strike 

 from due north to about N. 20° west; these folds pitch to 

 the south, with the result that the Carboniferous strata 

 dip under the Permo-Carboniferous strata in that direction 

 and disappear from view as the Hunter River is approached. 

 The strata have also been intersected by a number of strike 

 faults striking a little west of north; these have produced 

 much duplication of strata and an intimate mixing up of the 

 Lower Carboniferous marine beds with the Middle and 

 Upper Carboniferous terrestrial beds. Denudation has 

 nowhere in the region now under consideration exposed the 

 underlying Devonian strata, consequently the base of the 

 Lower Carboniferous strata is not visible, therefore a com-
