428 GEOLOGICAL NOTES. 



Only a few sections of these lavas have as yet been micro- 

 scopically examined by the author. They appear to be closely 

 related to the copper-bearing andesitic lavas of Kiama, which, as 

 will be described in a subsequent note, are probably of Permo- 

 Carboniferous age. Some of the older lavas which have emanated 

 from the Canoblas, are also copper-bearing, as at the copper mine 

 near Walli. 



The Pinnacles, a mammillated hill about one mile northerly 

 from the " Old Man Canobla," probably marks the site of a para- 

 sitic cone
