GEOLOGY 



By Sylvia G. Whincup, M.Sc, Mineralogist. 

 The area covered by this preliminary survey is a strip of 

 country on the western side of the Snowy River, between Suggan 

 Buggan in the north and W Tree in the south. A description of 

 the geology of this area is included in the excellent reports by 

 Howitt (2) and (4), who spent many months in northern Gipps- 

 land, and also by Ferguson (1). It is not felt that very much 

 detailed geology can at present be added to these reports, as it 

 was not possible to make more than a hurried visit to most of the 

 localities mentioned. However some interesting, if somewhat 

 disconnected, observations are recorded. 



Description of Area. 



Most of the rocks exposed in this area belong to the series 

 known as the Snowy River Porphyries — these consist mainly of 

 volcanic rocks of Lower Devonian age having a total thickness 

 of some 2,000 feet. On the relatively flat-topped plateau between 

 W Tree and Wulgulmerang, the porphyries are covered in places 

 by remnants of Tertiary basalt flows. To the west, the land rises 

 gradually to a ridge running north and south between Mt. Worn-
