The difficulty about this section is to ascertain sharply the line of 



junction between the decomposed metamorphic beds 

 Section in Aurunga, 



and the sandstones, &c., whicn are largely formed 

 of gneissose materials. On the right of the section a massive pebble 

 bed rests on the edges of the disturbed and decomposed gneiss, while on 

 the left red clays and white and ferruginous grits with much false 

 bedding occur next the gneiss. 



In the next reach we meet with the following well exposed sec- 

 tion, the dip throughout being q. p. north : — 



Ascending section in Aurunga River, south-east of Juggtilduqga. 



(Gneiss partly epidotic and decomposed ; might be mistaken for Talchirs.)
