12 CATALOGUE OF MINERALS ; 
American with molybdenite, in the Leviathan with iron pyrites 
and fluorspar, and in the Ly-e-moon occasional small crystals of 
wolfram were noticed among the tin ore. Specimens of wolfram 
in quartz have also been obtained from Mackay. 
XIV.—SULPHATES. 
BARYTES—Heavy Spar—Comp. Ba S O,. 
Barytes has been found on the Herbert River and in the 
Kilkivan district ; also on joints in the granite walls of the Old 
Identity reef, Charters Towers. 
ANGLESITE—Comp Pb S Q,. 
Anglesite has not been frequently noticed; it occurs near 
Townsville, in the Tinaroo district, and in the Star River district, 
assaying 67 per cent. of lead and 307 ozs. of silver to the ton. 
GypsumM—Comp. CaS O,. 
Selenite crystals have been found at Bulimba a few feet below 
the surface when excavating for the Brisbane Gas Company’s 
works. Good specimens also come from the Warrego district. 
To the west of the Richmond Downs brown sandstones are 
extensively veined with gypsum, and it is stated that beds of the 
mineral are frequently met with in sinking wells in that part. A 
little gypsum occurs in some of the Charters Towers lodes, as in 
the Queen reef, associated with sulphides and steatite. In the 
Old Warrior, one of the ‘‘ outside” reefs of this field, a good deal 
of selenite was found in the brownstone. In the North Australian 
a perpendicular dyke of diorite, five feet wide, running east 15” 
south, cuts the reef, and veins of gypsum occurs on the sides of 
the dyke. Specimens of selenite stained green with carbonate of 
copper were obtained from the Manchester reef on the Marengo 
goldfield. 
GREEN VITRIOL—Coprreras—Comp. FeSO, + 7 H, O. 
This mineral occurs in the decomposing iron sulphides of the 
Gilberton district, in fine crystals of very pale blue to transparent 
white colour. 
BLUE VITRIOL—Comp. CuS O, + 5 H, O. 
Blue vitriol was found in the waters issuing from the Mount 
Perry copper mines, and not unfrequently has been noticed on 
the decomposing chalcopyrites of various localities, as at Herberton 
in the Ironclad mine, and Stewart’s T claim, and at Ravenswood 
in the Black Jack claim, also in the West Mount Morgan mine.
