CARBONIFEROUS AND PERMO-CARBONIFEROUS ROCKS, N.S.W. 251 



The Rocky Creek Series is described as consisting of heavy 

 conglomerates containing pebbles of granite, aplite, quartz- 

 porphyry, rhyolite, trachyte, dacite and andesite. The con- 

 glomerates are interbedded with flows of rhyolite, trachyte 

 and andesite of a similar character to those of the pebbles 

 in the conglomerate, together with beds of tuff of the same 

 composition passing into tuffaceous and gritty sandstones^ 

 Further brief reference to the Carboniferous formation is 

 made by Prof. W. N. Benson in Parts II and III of his 

 Geology of the Great Serpentine Belt, 



7. In 1913, A. B. Walkom 1 described briefly the Carboni- 

 ferous strata which occur in the Glendon Brook District 

 near Singleton. 



8. In 1915 M. Aurousseau 2 described the petrology of 

 some of the Carboniferous igueous rocks from Martin's 

 Creek and Eelah. 



Acknoivledgements. — My thanks are due to three of the 

 geology students of the Newcastle Technical College, viz.: 

 Messrs. V. B. Collins, T. Hynd and A. F. Newman for much 

 help in the field; they accompanied me on many of my field 

 trips and assisted in making the traverses upon which the 

 geological sections are based. My thanks are due to Prof. 

 W. N. Benson for permission to use the list of marine fossils 

 compiled by him, and to Dr. A. B. Walkom for the palaeon- 

 tological note in Appendix J. I have to thank Mr. W. R. 

 Browne and Prof. T. W. E. David for the information 

 regarding the glacial beds of the Lochinvar district and 

 for the geological section of that locality which they have 

 prepared and allowed me to use, and also to thank Mr.
