3S6 PROCEEDINGS OF SECTION C. 



places, when looked at from one point of view, an appearance of a 

 somewhat irregular stratification can be seen in the conglomerate," 

 but they consider this appearance '* due to shearing stresses." 

 This is in the conglomerate, but in small mudbands interbedded 

 between the sandstones which dip conformably witli them and the 

 conglomerates, and which underlie and overlie them, one of the 

 writers of this paper has found over fifty laminae to the inch. 

 Higher up the creek they did find in one place " several flattened 

 and striated stones resting on the lower side (not bottom)," and 

 found it " difficult to perceive how icebergs could have deposited 

 stones in this manner." The place to which they refer is a bed of 

 conglomerate conformable with the sandstone ; the surface portion 

 has become partially decomposed and the striated stones are found 

 in situ on the lower bedding plane of the stratum, which, of 

 course, with a dip of over 40°, would be the present side. These 

 stones, therefore, which they describe as resting on this side are 

 really the lower stones of this conglomerate bed. The fact is they 

 recognise that the Triassic sandstones are stratified, but do not 

 perceive that the interbedded mudstones and conglomerates 

 are also stratified because the bedding planes are not quite so 

 distinct. 



They observe that between the large quarry of Triassic sand- 

 stones, in which Gangamojiteris occurs, and the Korkuperrimul 

 Creek below it striated stones are numerous, but apparently have 

 not perceived that some of the boulders come from and are still 

 found embedded in the sandstones themselves, and some of the 

 very hardest quartzites are found in this sandstone still retaining 

 the brilliant polish on their flattened sides, their ends and edges 

 being still rough and subangular ; and occasionally also striated 

 stones are found, while the conglomerate overlies it conformably, 

 and is also found in lower beds conformably. 



A few hundred yards away they again find " unstratified rocks 

 bearing striated stones." So we find this superficial deposit is 

 imstratified, that is to say, the stratification of the rocks from 

 which it has come is obscured by the denuded material from the 

 higher beds, but when this thin mantle of " talus " is removed 

 the dip is 20° N.E. They state also " these rocks are overlaid by 

 very irregiilarly stratified tumultuous-looking sandstones, and these 

 sandstones," they think, "are simply beds associated with the 

 glacial deposit," and they "found striated stones in them." 



These observations agree with our own. The wonder is that 

 they did not see that in this they had a key to the whole of this 

 formation, the only difference being that in some places the evi- 

 dences have to be sought for more than at others. " At one spot, 

 between the 'big' quarry and the 'small' quarry," they state 

 they found " a loamy matrix in which arc scattered angular frag- 

 ments of soft sandstone in all positions." " This," they say, 

 " rests upon the denuded edges of well-stratified Triassic sand-
