The Gold Deposits of Mount Morgan^ Queensland. '.V-V-> 



No. 8. — Iron stained siliceous sinter from west side of 



dyke, 10 oz., 14 dwt. of gold per ton. 



I town the hillsides to the north, 

 west and south, similar deposit is 



. everywhere met with, a frothy, 



g spongy matrix, sometimes alumi- 



| nous and sometimes siliceous, 



| generally irons tain ed, and occa- 



~~ sionally associated with large 



| masses of red and brown haema- 



p 



i tite, but gold has as yet only 



I" been obtained from a few places 



| away from the hill-top, although 



~ naturally there has been vigorous 



L" prospecting wherever the "forma- 



I i 3 tion " resembles that of Mount 



J 3 Morgan. 



| | After a careful study of the 



* t whole formation I have come to 



§ I the conclusion that nothing but a 



1 s _ thermal spring in the open air 



S '■: could have deposited the material 



~ $ under consideration. The frothy 



I o siliceous sinter agrees in every 



J respect with the deposits of the 



| New Zealand and Iceland geysers 



* and of the still more wonderful 

 £ hot springs of the Yellowstone 

 | National Park, so graphically and 

 I scientifically described by Dr. A. 

 S C. Peale (12th Annual Report of 

 I the United States Geological and 

 c Geographical Survey of the Terri-
