GEOLOGICAL NOTES. 
By E. 0. Marls, M.B., B..A ., B.E. 
From the geologist’s point of view the residents of 
most of the other Australian capitals must be envious of 
the great variety of geological structures and problems 
within reach of Brisbane. Of the many interesting locali- 
ties, the Fassifern district is one of the most attractive, 
whether it be for the study of the divers and diverse 
igneous rocks and of the vulcanicity which they represent, 
or for the investigation of questions relating to the de- 
velopment of the beautiful varied scenery, as well as the 
striking escarpment of the Main Range. 
The camp site at the entrance to the Mt. Edwards 
Gorge was well situated for the geologist, but it was a 
matter of very keen regret to the present writer 1 that his 
ambulatory powers did not permit of taking full advan 
tage of the opportunity which the trip offered. These 
notes, in consequence, are a general impression and do 
not represent new observations. 
While there are marine strata of Carboniferous age at 
Mt. Barney, the oldest rocks in the vicinity of Mt. Edwards 
are the sandstones and shales which Mr. J. H. Reid, of 
the Geological Survey, has shown to belong to the Walloon 
(Jurassic) series constituting the coal measures of Rose-
