CARBONIFEROUS AND PERMO-CARBONIFEROUS ROCK?, N.S.W. 295 



Brisbane University states that a series like the Kuttung 

 occurs near Warwick, in Queensland. 



(ii) In the State of Victoria it is probable that the 

 Kuttung series are in part represented by the red rocks of 

 Mansfield famous for their fossil fish. 1 The Avon River 

 sandstones of Victoria, containing Lepidodendron australe 

 and a considerable thickness of tuff, lavas and conglomerate, 

 and particularly the similar strata at Iguana Creek on the 

 Lower Mitchell River, with Cordaites australis McCoy, 

 Sphenopterls iguanensis McCoy (allied to Sphenopteris 

 artemlsifolia of the Lower Carboniferous rocks of Nor- 

 thumberland), and also the Mount Tambo, the Macallister 

 and Wonnangatta Rivers rocks may also belong to Kuttung 

 time. No other representatives of this remarkable form- 

 ation are known from elsewhere in Australia, and there is 

 no record of any such strata in Tasmania. 



It would appear that this great "Flysch facies" of 

 Australia, the " Upper Siwalik " of the late Palseozoic 

 Himalayas of Australia, was more or less restricted to 



Queensland and New South Wales. 



In attempting to correlate rocks of the Kuttung series 

 with those of extra- Australian areas, one naturally relies 

 on Dr. A. B. Walkom's paleeophytological determinations 

 herewith, which place its flora low down in the Middle 

 Carboniferous, a flora either high in the Culm (Hessian 

 Culm), or near the horizon of the Pottsville Conglomerate 

 (Millstone Grit) series. One is also guided by the physical 

 and geographical characters of the deposits, and their 

 relation to diastrophism, mountain-building, and the special 

 petrological suite which accompanies such types of fold 

 mountains. One specially seeks too to find analogues, in
