Geological Struct'ure about Mornington. 35 



Considerable confusion appears to exist as to the names of the 

 small creeks or gullies which run down to the Bay, and we use 

 the local names as far as we have been able to ascertain them. 

 As a matter of fact many of them are too small to have widely 

 recognised ones, and generally bear the name of the owner of the 

 land through which they run, and to these facts is due the 

 deviations which Mr. Kitson's map shows from local usage. 



The Sections. 



Franks ton Brickyard. 



In the yard of the Frankston Brick Company, south of the 

 pier, the succession is— 



Red sands, grits ai:id white clay 



Basaltic clay 



Conglomerate C?) 



Granite rock. 

 The granitic rock was reached in a well put down for water and 

 the spoil heap appears to show the presence of the conglomerate. 

 Considerable slipping has taken place at some spots. A shaft 

 was put down a few years ago in search for coal at about low 

 tide mark, slightly to the north of this spot, but all traces have 

 now been washed away. 



Sweetwater Creek. 



The road cutting near the mouth of Sweetwater Creek 

 (Naringalling Creek of Mr. Kitsoii) is through a landslip, but the 

 true succession can easily be made out on the hill. We get : — 



Red sands, grits and white clay 



Basalt 



Conglomerate 



Granite rock. 

 In places there is considerable displacement by slipping, and 

 apparently the whole face has come down without, however, 

 much disturbing the order of the beds. About 25 years ago, 

 according to Mr. B. Baxter, a local resident, a considerable fall 

 took place, which completely blocked the traffic, and fragments of 

 the basaltic rock are still to be seen on the beach, evidently 

 derived from this or previous landslips.
