1. A. K. Selwyn began the literature on this area in a report 

 on the Geological Structure of the Colony of Victoria, the Basin 

 of the Yarra, etc. ; Votes and Proceedings of tin' Legislative 

 Council of Victoria. 1855-1856, Vol. 2, Pt. I., with plans and 

 sections. 



In 1876, R. Brough Smythi briefly described the general mining 

 features of the Diamond Creek gold field. He mentions the occur- 

 rence of eurite at Diamond Creek, and draws a parallelism be- 

 tween it and the acid dykes at Mount Bischoff, Tasmania. He also 

 traced a line of older basalt and gravels from Kangaroo Grounds 

 past the Dandenongs to the River Latiobe, and thence to near the 

 coast in South-West Gippsland. In 1894, R. A. F. Muriay- visited 

 the auriferous " cement " deposits near Greensboro ugh. Eltham 

 and Kangaroo Grounds, and reported very briefly thereon. 



In 1895, 0. A. L. Whitelaw, of the Victorian Geological Survey,, 

 made a rapid survey of jjortion of the goldfields between Warrandyte.. 

 Greensborough and Queenstown. He mentions a distiiK'tive l)and 

 of sandstone traced from 'the River Yarra to Diamond Creek, and 

 intersected by spurs and veins of a dioritic dyke. He was of the 

 opinion that the quartz reefs were formed along a line of anticlinal 

 fracture. 



H. S. Whitelaw"' iu 1899 noted the occurrence of sribnitc in 

 (juartz leefs. and in certain bands of the silurian at Diamond 

 Creek.
