22 NOTKS ON MT ANNE AND TllK WELD RIVEU VALLEY. 



Reid states that he knew it was tillite. The present writer 

 found ample confirmation in the numerous ice-scratched 

 pebbles which were found in greater profusion than at 

 Wynyard, although, as at the latter place, large patches of 

 the tillite occur in which no scratched pebbles can be found. 

 The glacial beds seem to occur between the 1,400 and 1,800 

 foot contour lines, and appear to be overlain by beds of a 

 coarse sandstone at a height of 1,800 feet above sea level, 

 but neither its highest point nor its boundaries can be 

 ascertained from the track. It rests, on both sides, on 

 Cambrian quartzites. 



The second occurrence of glacial tillite of this age was 

 noticed in the course of the Weld about 15 miles from its 

 mouth, at an altitude of about 500 feet. The river has cut 

 through the morainal deposit, which is exposed on its bank. 

 It is similar to the Wynyard formation and that just 

 described, on Mt. Mueller. The proportion of red granite 

 pebbles and boulders is high, and several erratics are of 

 considerable size. 



It may be worth noting, in passing, the fact that four 

 occurrences of the rare Permo-Carboniferous glacial till, 

 namely those at South Cape Bay, Wynyard, and the two 

 described, lie in an almost straight line, which if produced 

 passes near Bacchus Marsh in Victoria, where similar beds 

 occur. This may be only a coincidence but it is a point to 

 be borne in mind when investigating these beds. 



These beds are succeeded by 300 feet of a coarse but 

 regular conglomerate of Permo-Carboniferous age, resembling 

 in general appearance the recent river drifts of the Derwent 

 and elsewhere, and con.sisting of a hard yellowish matrix 

 cementing together quartzite pebbles about the size of a cricket 

 ball. Its age is definitely fixed by some strata that occur in its 

 upper layers on the ridge to the east of the river and which 

 contain fenestella. The conglomerate appears to be the river 

 drift or delta deposit of some ancient river which perhaps 

 flowed through the marked gap which now separates the 

 Arthur and the Frankland Ranges and is continued east in 

 the deep valley south of Mt. Anne and north of Mt. Weld. 



Lower down the Weld, Permo-Carboniferous mudstones 

 flank the valley. In the bed of the river they are the lower 

 marine series and contain many of the typical fossils of 

 those rocks. They flank the southern end of the Snowy 

 Mountains and probably the eastern side of Mt. Weld. An 

 outcrop of horizontal strata under the diabase organ pipes 

 of the northfin rnd rif Mt. Weld could be distinguished from
