The earlier ‘‘Grey Phase’’ thus seems to be most nearly 
related to the voleanics under discussion, both in point of 
time and in chemical composition. The facts appear, then, 
to warrant the tentative assumption that the Permo- 
Carboniferous volcanics are genetically related to the 
granitic rocks of the ‘‘Grey Phase’’ as exemplified by the 
‘*Hornblendic, Dioritic, and other basie granites’’ of New 
England’? and the ‘‘ Maryland’’ and ‘‘Greymare’’ granites 
of the Stanthorpe area.
