TINDALE—SUBDIVISION OF PLEISTOCENE 637 
Bed ‘'B,’’ Fine-grained, cream-coloured limestone, moderately friable, with a 
few glauconite grains, siliceous and calcareous sponge spicules and brachio- 
poda (Magellama ef. isolita), Washings contain foraminifera (Anomalina 
ammonoides, Cibicides mundulus). 
Bed ‘‘C."’ Cream to pale-ochreous-coloured lbuestone containing littoral marine 
shells (Macrocallista sp., Turritella sp. and Chione striatissma). Matrix 
resembles a consolidated shore sand and dune rock. 
Bed “D.’’ Mottled eream-coloured travertine or freshwater limestone, having a 
breceiated structure. A fractured surface shows apparent negative casts of 
vegetable cells, also traces of casts and moulds of ? fresh-water molhisean 
shells. 
‘The more or less recent aspect of the fossils in ‘*C,’* especially in the 
occurrence of Chione striatissma, point to a Werrikooian (Upper Phocene) 
age. ‘'D’’ is nndoubtedly of Pleistocene age, as it agrees in structure and 
organie contents with similar deposits in the distriet.”’ 
This determination suggests that the shore deposits characterizing the vicinity 
of Tailem Bend, on the postulated Reedy Terrace may be Pleistocene in age. 
Half a mile wpstream, at Section 340, Tundred of Seymour, the clilf displays 
a section of sediments within the Murray Valley itself with marine beds of 
Miocene age planed off at a level of 20 feet (6 metres) above the water, covered by 
astuarine deposits and clay, There is a kunkar horizon at 33 feet (10 mueti'es ) 
followed by clay beds to 47 feet (14 metres) above whieh, to the local level of the 
bank at 50 feet (15 metres) is soft and hard kunkar, and a thin layer of sandy 
aoil. Allowing for local river level, the discontormity at 20 feet (6 metres) seems 
to belong to the Woakwine Terrace which followed Reedy Terrace, 
EAST AVENUL TERRACE. 
The Bast Avenue Terrace comprises a large series of dunes and swales of 
which the later ones fall together as East Avenue Range, while earlier ones are 
grouped as Baker Range. 
The Kast Avenue Range series is usually three to five miles wide while 
Baker Range dunes vary in width from about seven to ten miles. 
The double series of dunes identified as the shore deposits of this terrace form 
a belt ten to fourteen miles wide; far greater than on any other terrace. It may 
imply a relatively Jong period during which dune deposits were being built up 
on the terrace. This may be a significant pointer when correlation with terraces 
elsewhere is under consideration, 
The front of the terrace lies between fifteen and thirty miles inland from the 
present coastline. It has been traced in the field continuously from just north 
of the northern boundary of the Hundred of Landscer to a point eight miles south
