206 PROCEEDINGS OP SECTION C. 



On the Desert Sandstone are immense areas of basaltic beds, 

 which are largely developed on the Upper Flinders. They are 

 probably Tertiary, and must have been poui'ed out before any 

 extensive denudition of the Desert Sandstone took place. But 

 after the upheaval of the latter and the carving out of the 

 valleys, a second period of volcanic activity supervened, and 

 streams of basaltic lava flowed down the valleys. To this latter 

 period belonged the remarkable thermal spring which gave rise 

 to the auriferous deposit of Mount Morgan. 



This will conclude my remarks, as I have never enjoyed the 

 opportunity of studying Tertiary and Post-Tertiary geology in 

 Queensland. 



I have tried to place before you an account of the most recent 

 views. I have thought it better in some cases to repeat what 

 has been said before than to omit any poi'tion of the story. If, 

 on the other hand, I say something different from what I may 

 have said last year, or the year before that, I claim to have 

 enlarged my knowledge of the subject in the time. I hope to 

 have made clear to you the nature of the problems we have to 

 face. Above all, I hope to have shown how extremely frag- 

 mentary is the story as told in Queensland : — how almost 

 everything that can be called a formation is unconformably 

 related to older rocks : — how formations of widely different dates 

 may, under similar conditions of disturbance, pressure and meta- 

 morphism, assume the same lithological characters : — and, again, 

 how the same formation may be locally metamorphosed, so that 

 one portion of it, for instance, may be a coal-field and another a 

 gold-field ; and, finally, I hope it has been suggested to you that 

 we look for help in unravelling the structure of Queensland to 

 workers in other lands, and to meetings such as this of those 

 who are — 



Not incurious in God's handiwork.

1.— NOTES ON THE METAMORPHIC ROCKS OF THE 

 OMEO DISTRICT, GIPPSLAND. 



By A. W. HowiTT, F.G.S., of Sale, Victoria. 



INTRODUCTION. 



The study of those rocks which are now termed Metamorphic 

 commenced when Hutton, at the end of the last century, 

 published his " Theory of the Earth." Since that time the 

 subject has attracted the attention of geologists with an ever 

 increasing interest. Yet it is only now, after the lapse of nearly 

 a century, that the course of early speculative theorizing and
