(3) PORT ELLIOT. 



At Port Elliot we get more variations in the igneous rocks 

 than elsewhere. They form a fringe of rocky coast extending 

 for about a mile and a half, notched by sandy bays of various 

 sizes, the largest being about 600 yards wide. These are 

 due in some measure to the jointing of the granite (fig. 2).

The igneous rock never extends for more than 300 yards 

 inland, and indeed in places does little more than form the face 

 of a scarp sloping to the sea. The real landward extent of the 

 outcrop cannot be determined, as it is overlain by a deposit 

 of ''travertine," and at its western extremity disappears under 

 the horizontally-stratified Permo-Carboniferous glacial beds.
