1S2 ON THE GEOLOGY AND PETROGRAPHY OF BATHURST, N.S.W., 



vi. Minerals of Bathukst, 



Before dealing with the formations and the rocks in detail, it 



may be well to enumerate the minerals and rocks I have found in 



the district. 



Minerals. 



Note. — The following are also reported from Glanmire : — 

 Rhodonite (Annual Report Dept. Mines, N.S.W., 1885, p. 141), 

 manganese ores, and baryta (Annual Report Dept. Mines, N.S.W., 

 1884, p. 161). 



1. Calcite. — Calcite is found in veins in the limestones on the 

 Cow Flat Road, about four miles south of the village of Perth. 

 It also forms veins in fissures in the granite. This seems an 

 unusual occurrence, and only two instances came under my notice. 

 It was rather plentiful in a joint or fissure, cut through in the 

 large well of the water-works, Bathurst. There is little doubt 

 but that it is a secondary mineral, formed from the decomposition 

 of some lime felspar.
