Geology of the Country about Anglesea. 53 



SUMMARY. 



The polyzoal limestones of Airey's Inlet, Point Addis and 

 Spring Creek are on the same horizon. The black sandy 

 clays of the Anglesea coast are of marine origin, and are 

 apparently the equivalents of the rich marine beds of Spring 

 Creek to the eastward and of the lignitic series which rests on 

 the Jurassics to the west of Airey's Inlet. The presence of a 

 tuff interbedded with the sandy clays of the series at Point 

 Roadknight goes to show that the basalts and tuffs of Airey's 

 Inlet are intercalated in beds which are the equivalents in age 

 of the marine clays of Spring Creek. The older l)asalt of this 

 district is then of typical Janjukian age. 



The country between Geelong and Anglesea is a coastal plain 

 trenched by a broad, mature valley floored by basalt. This is 

 probably the old valley of the Barwon, which entered the sea 

 not far from its present mouth. Near Anglesea the coastal 

 plain is not greatly dissected.
