380 PROCEEDINGS OF SECTION C, 



ance of being unstratified. The sandstone about here also contains 

 striated stones as well as waterworn pebbles. There is a section 

 one and a half miles up the Korkuperrimul Creek, north of the Big 

 Quarry, dipping 45° S.E., showing for a short distance highly 

 contorted sandstone and clay bands with striated stones ; these 

 latter rest on well- stratified sandstones, all 37° S.E. Two miles 

 higher up the creek there is a section of sandstones and mudstone 

 45° S.W. From here the dip gradually becomes less as we 

 proceed up the creek, the average being 42° S.W., and the beds 

 can be examined consecutively for nearly one mile higher up. 



Where the sandstones are overlaid by conglomerate the surfaces 

 of these sandstones are roughened as if by currents ; some of the 

 stones are half imbedded in the sandstone. The lowest beds seen 

 in this section are stratified clays containing great numbers of 

 striated stones ; these are overlaid by finely stratified sandstones 

 and then conglomerates. Here several basaltic dykes of varying 

 thickness have cut through the beds, and close to the larger dyke 

 a fault occurs; the downthrow is about 95ft., and there are signs of 

 slicken-sides. These faultings do not, however, affect (/reatli/ the 

 estimate of position and thickness of the beds, which can be 

 followed still further up the same creek for nearly half a mile, 

 where the deposit on this side of the range terminates against the 

 Silurian spur, near to which several Graptolite^ have been obtained 

 by us. From this creek we may cross the Lerderderg Ranges, 

 where outlines of the beds are again seen, and thence across the 

 river of that name. 'I'he deposit is again found maintaining its 

 usual characters ; on both sides of the Lerderderg River and on the 

 ranges the dip is 3o° to S.W. Skirting the river at the head of 

 the cultivated river flats a section of drift is seen forming a river 

 cliif about 50ft. high, the upper beds of which are covered by old 

 river wash. Here the lower part is stratified clay in places, through 

 the whole of which great numbers of striated stones are scattered, 

 some several feet in diameter, and these in some cases have deflected 

 the beds. FolloAving the irrigation channel down the river, at the 

 junction of the Silurian with this deposit are to be seen the grooves 

 and striae common to nearly all the other localities, running from 

 south to north. Another section is seen about half a mile down 

 stream, on the same side, of fine sandstone and mudstone, with 

 small striated and waterworn stones ; the dip is 20° to 25° S.W. 



At Goodman's Creek, a tributary of the Lerderderg River, there 

 are sections of drift containing good examples of striated stones 

 and many varieties of granite. Here also the beds of sandstone 

 and mudstone are intercalated, dipping 25° to E.S.E., jointed as at 

 the Werribee Gorge. Returning to the Lerderderg River on the 

 opposite side to that already described, sections of mudstone and 

 sandstone are seen dipping \b° E.S.E. Further up the stream a 

 fine section is exposed, consisting of blue grey clay, stratified and 

 containing numbers of stones, one 5ft. 6in. x 3ft. 6in. x 2ft. 6in. ;
