20 NOTES ON MT. ANNE AND THE WELD RIVEK VALLEY. 



of Mt. Anne and extending eastward until obscured by the 

 diabase of Mt. Weld. 



South-east of the latter mountain it emerjires again in 

 a small outcrop round the mouth of the Weld River, where 

 it forms a low line of hills some three miles long en the 

 west side of the river, and on the east of the Weld a 

 number of isolated cone-shaped, buttongrass covered hills 

 known as "Glover's Paddocks." The quartzite is here dip- 

 ping at an angle and in a direction similar to the beds on 

 the west of Mt. Anne. Five miles up the Weld from its 

 junction with the Huon the older quartzites disappear under 

 Permo-Carbcniferous and Trias-Jura sediments, which also 

 cover the older recks to the east and form the divide between 

 the Weld and Denison Rivers. To the west it is obscured 

 by the diabase of Mt. Weld. 



At a spot some twelve or fifteen miles up the Weld the 

 older rocks again appear in the bed of the valley, stretching 

 right across from Mt. Anne to the Jubilees and northward 

 to the head of the river. The Jubilee Range appears to con- 

 sist of the same massive white quartzites, which, however, 

 do not extend farther east than the foot of the Snowy 

 Mountains. To the north, similar beds compose Mt. Bowes 

 and the southern foothills of Mt. Mueller. On Mt. Bowes 

 the quartzite is dipping at an angle of about 60 degrees a 

 few degrees south of west. 



On the west of Mt. Bowes are large beds of a hard 

 reddish slate resembling burnt fireclay, which appear to 

 he included in the quartzite beds. In the course of the 

 Weld roughly 12 miles from its mouth are considerable beds 

 of grey slate resembling in general appearance the Dundas 

 slates of the West Coast (Cambro-Ordovician), but no 

 indication of its exact horizon^was found. Opposite the end 

 of the Jubilee Range there is a small outcrop of serpentine 

 or serpentinised rock to be seen in the bank of the river. 

 It is overlying unconformably some beds of white sandstone 

 which show no signs of ct)ntact. On the old track just above 

 this outcrop is a corner peg blaze apparently of an intended 

 claim, but no application was ever lodged. A bed of grey 

 slate of small extent lies across the Port Davey track to the 

 north-east of Mt. Bowes near the old Junction Huts. 



The older rocks extend eastward in the Russell Falls 

 River Valley as far as Pine Hill, three miles west of 

 Fitzgerald Station. (On the beforementioned Geological 

 Map they are shown as extending some eight miles too far 

 east in the Tyenna Valley). They are overlain to the north
