Tlie Iceland spar variety occurs at Angaston, as do also 

 various coloured marbles. Ordinary marble at Kapunda, and 

 in tbin veins in tbe metamorpbic rocks near Franklin Harbour. 

 Calcite also occurs at tbe Yudanamutana Mine. Ulricb re- 

 ports wbite calcite, generally imperfectly crystallised, at tbe 

 Blinman Mine. Tate reports it between Mounts Parry and 

 Playfair, Central Australia ; in tbe stalactitic form at Cape 

 Jervis ; massive and in scalenobedrons at New Mecklenburg, 

 near Lyndocb ; and also states tbat it occurs in tbe quartz 

 veins in tbe metamorpbic rocks in tbe neigbbourbood of tbe 

 Peak, and as a cellular calcareous tufa forming tbe top crust 

 of tbe Mound Springs of tbe same neigbbourbood. Calcite 

 also occurs at tbe following localities : — Mount Crawford, Ard- 

 rossan, Eapid Bay, Mount Gambler, Point Curtis, Macclesfield, 

 and at Mattawarrangala, in largely crystalline masses. 



Tate bas described a nearly black, largely crystalline calcite 

 (tbe colour due to finely divided carbonaceous matter) occupy- 

 ing a vein in a dark-coloured slate at AVbyte-Tarcowie. 



Burr mentions tbese additional localities for tbis species : — 

 Barossa, Flinders, and Mount Lofty Eanges ; in tbe form of 

 calcareous tufa at Flinders and Barossa Eanges, Depot Creek, 

 near Mount Arden ; at Eapid Bay, Crystal Brook, and Eivoli 

 Bay; also on tbe plains near Mount Hawdon. 



AeA-GONITE 



Occurs associated witb native copper and cbalcocite at tbe 

 Wallaroo Mines; in tbe form of, long prismatic crystals at 

 Armagb, near Clare ; and, according to Ulricb, at tbe Blinman 

 and Oratunga Mines. 



Dolomite. 

 Selwyn mentions tbis species as occurring at Victoria Creek, 

 "Williamstown, (tbe variety is not stated), and J. E. T. Woods 

 bas noticed it in tbe limestones of Mount Gambler. Burr 

 mentions tbe following localities : — Bel^idere Eange, Barossa 

 Eange, Eapid Bay, and near Mount Barker. Pearl spar at 

 Eapid Bay and nortb-east of Adelaide. I bave found it as a 

 pseudomorph in a specimen from Central Australia. 



Fluoeite {JEluor Sj^ar). 

 Tbis mineral was found massive in considerable quantity at 

 tbe Paramatta Mine, Torke Peninsula — 'tbe colour varying 

 from colourless to sea-green. Tbe purple-coloured mineral 

 occurs in small quantity at tbe Moonta Mine. Professor Tate 

 mentions it as follows : — In silicious limestone of tbe Pre- 

 Silurian age, at Field Eiver, between Eeynella and tbe coast, 

 and in Lower Silurian limestone at Parara, near Ardrossan, 

 Torke Peninsula — tbe blue variety baving been discovered in
