(a) Red Clays and Gravels. 



In a superior position to the mottled sands and clays 

 are red and brownish clays, which contain at various horizons 

 layers of gravel and sand. These beds are less indurated 

 than the mottled series, and often obscure the face of the 

 latter through being washed down the face of the cliff by the 

 rain. An unconformity between the two sets of beds can be 

 recognized by a slight shelf in the cliffs (see pi. xxviii.) which 

 marks the dividing line, as well as an uneven line of erosion 

 between them, as is well seen in the yard at the landward 

 end of the jetty, where an eroded gutter in the older beds is 

 occupied by the gravel of the newer (pi. xxix.). In the sea 

 cliffs the newer beds attain a thickness of 15 feet, or less; 

 they are also well exposed in Clay Gully, which has its outlet 

 at Ardrossan jetty, and are there seen to be at least 20 feet 

 In thickness. They are comparable to similar clays that 

 overlie the mottled beds on the eastern side of Gulf St. 

 Vincent, and although quite independent of the existing 

 drainage are undoubtedly Recent in their age. 



The uppermost bed on the Ardrossan cliffs, as well as 

 the most common surface deposits throughout the region now 

 described, is a nodular travertine more or less associated with 

 marls and loose sand. 



A visit was paid to Balgowan (Port Warrenne), on 

 Spencer Gulf, 11 miles north-west of Maitland. On the 

 northern side of the jetty the cliffs consist of recent reddish 

 clays, about 60 feet in height. At the jetty (Point War- 

 renne) there is a cliff of travertine limestone, 12 feet in 

 height, which in parts is very compact and breaks away in 

 large blocks. A short distance south of the jetty a flat- 

 topped reef of travertine limestone runs for a considerable 

 distance out to sea. In travelling between Maitland and 

 Balgowan no definite outcrops were noticed, but the rises in 

 the ground were usually covered by loose stones of travertine.
