OCCURRING IN TASMANIA. 21 



In slugs up to many pounds in weight, associated with 

 native copper, at the King Lyell Mine. (H. W. 

 Judd.) 



16 Clinochlore. — {Basic magnesium and aluminimn 



silicate.) 



In large masses and occasionally crystalline bunches 

 of a pale metallic green colour. Near Mt. 

 Heemskirk. 



Abundant in fine groups of hexagonal crystals of a 

 dark olive-green to black colour. The plates are 

 often over one inch in diameter. Near the 

 Hampshire Hills Silver Mine, Hampshire Hills. 



At Anderson's Creek in minute, almost microscopic, 

 radiating bunches of a dark colour. (W. H. 

 Twelvetrees.) 



17 Chlorite. — {Basic silicate of magnesium and alu- 



minium.) 



In schist, and as beautiful bright green fan-shaped 

 crystals in honey-combed quartz — Crown Lyell 

 Mine — species undetermined. (H. W. Judd.) 



Occurs pseudomorphous after felspar — Block 4891- 

 93m, Ben Lomond. (Waller, ''Report on the Ben 

 Lomond District," 1901.) 



18 CopiAPiTE. — {Hydrous basic ferric sulphate.) 

 Results from the decomposition of pyrites, Colebrook 



Mine, Ringville, Khaki Mine, Whyte River, and at 

 Barn Bluff. The rock from the last-named locality, 

 when freshly broken out, soon becomes coated with 

 this and other sulphates. 



19 Crocoisite. — {Chromate of lead.) 



Rare as small crystals in gossan at the Silver Queen 

 Mine and at the Colonel North Mine, Zeehan. (H. 

 W. Judd.)

 known Dundas occurrence of this beautiful 

 mineral, by C. Palache, may be found in the
