AROUND THE ROSS OF MULL GRANITE.

The specific gravity of the inclusions is somewhat greater than 

 that of the granite. 



The absence of crushing, shearing, or any important faulting in 

 the granite, together with the fact that the intrusion is newer than 

 the structures in the schists, suggests that its present position is 

 practically that in which it solidified.

[The stick in the picture is 6 inches long. Six of the white marks indicate 

 some of the intrusions along the bedding, and one indicates the direction 

 of those along the strain-slips.] 



On the south-western shore of Loch na Lathaich, granulite is seen 

 in several places beneath granite, lending some support to the view 

 that the Ross of Mull granite is the bottom part of a large sill-like 

 intrusion which rests upon theMoine Schists, 1 and contains inclusions 

 derived from the floor.
