XXVI. ABSTRACT OP PROCEEDINGS. 



lying Permo-Oarboniferous is undisturbed and contains no 

 mineral veins. The ore formation therefore occurred in 

 the Carboniferous period. Volcanoes, besides affording us 

 magnificent scenery, are the source of our greatest wealth. 

 Our best soils of great extent are the basaltic, and fortu- 

 nately basalt was a fluid lava which spread over great areas. 

 To volcanic emanations and volcanic rocks we owe our gem 

 stones, opal, sapphire, ruby and diamond. Our best build- 

 ing stones such as Gib trachyte and Moruya granite are 

 igneous, our best road metal is volcanic basalt, and finally 

 our greatest metal wealth is derived from plutonic eman- 

 ations accompanying volcanic action.
