dark bands of which are of hzematite. These jasper-loaded conglomerates 
are strongest between the Paupugnee and Penn-air. 
Another very marked and exceedingly coarse form of conglomer- 
ate, which is, however, very local, is made up of debris of brecciated 
quartz-rock which was evidently derived from the denudation of the 
runs of ‘fault rock’* so common just outside the scarp in the granitoid 
rocks. The resemblance to the parent rock is great, and the close- 
ness of the coarsest debris to great walls or ridges of this fault-rock 
leaves no doubt in the mind of the observer as to the sources of the 
conglomerate fragments, 
Little more than a general idea of this lowest group can thus be 
E given; but there are features of interest at certain 
o 
points along the outcrop which can be illustrated‏ مر 
best by selections from our notes, and which may serve the future ex-‏ 
plorer much better than what could be given in a general sketch.

UA Goolcheroo, Mr. Charles Oldham notes that— 
<“ North-west of Wungymullay there are 100 to 120 feet or more of a grey and 
purplish, intensely hard quartzite, rather coarse and thickly bedded, resting on the 
denuded surface of the gneiss. Over this some thinner and 
SMES ces more flaggy beds. In the river gorge east of Wungymulla 
the lowest beds seen, not in actual contact however, with the metamorphic rocks 
are purplish colored, hard slaty beds, with some massive reddish quartzites, over these 
a succession of thick beds of grey quartzite with ferruginous bands. 
<“ Bast north-east of Wungymulla, greenish-grey and purple quartzites form the 
mass of the face of the hill, while there are some flagg 
Traces of a higher series and slaty beds above: these form the plateau above and are

* These walls of fault-rock often run right up to the scarp and are evidently con- 
tinued under the KADAPAHS. In one or two instances the dislocation of the KADAPAHS 
is with these runs.
