CHAPTER VI. 
RECENT DEPOSITS AND PLEISTOCENE. 
MARINE DEPOSITS NOW FORMING — WIND-FORMED ROCKS 
— SAND DUNES — ALLUVIAL DEPOSITS — TERTIARY. 
Recent deposits are conveniently divided into : — 
(1) . Marine or sea-formed deposits. 
(2) . AEolian or wind-formed deposits. 
(3) . Alluvial or river-formed deposits. 
No recent marine deposits are known near 
Sydney or on the New South Wales Coast. Not that 
such deposits have not been laid down, but there 
has been no elevation of the land, in recent times, 
to lift these deposits so as to form dry land. There is 
no mistaking the signs of upheaval, if upheaval there 
had been in recent times. The country between the 
mouth of the River Murray and Cape Bridgewater is 
a good instance — over two hundred miles in length — 
of a land tract raised from beneath the sea in Recent 
times. For twenty miles inland on this coast there 
are a series of raised beaches, with sea-shells and 
sea-cliffs. Almost anywhere beneath the soil one 
can find masses of marine organisms — shells, corals, 
polyzoa, &c. It might be argued that, although these 
are true marine deposits, yet the elevation did not 
take place in Recent times ; it might, perhaps, have
