MEsoTyPpE—Comp. hydrous silicate of alumina, lime, and soda. 
Occasionally noticed by Mr. R. L. Jack inthe basalts of the 
Peak Downs. 
ANALCIME—Comp. hydrous silicate of alumina and soda chiefly. 
Found in the amygdaloidal trap rocks of Strathmore Creek, and 
in the basalt of Peak Downs. 
CHABAZITE—Comp. hydrous silicate of alumina and lime with 
some potash, and generally a little soda. 
Chabazite occurs in the Peak Downs basalt, but its chief locality 
is the basalt of Toowoomba, where it was found by Hon. A. C. 
Gregory in large masses; this occurrence is very unusual and 
worthy of note. 
STILBITE—Comp. hydrous silicate of alumina and lime. 
Occurs on the Fitzroy River, and also at Toowoomba. 
TaLtc—Comp. hydrous silicate of magnesia with generally a 
little iron. 
I do not know of the occurrence of foliated talc in Queensland. 
Steatite occurs in some of the reefs of Charters Towers and 
Ravenswood, and in association with cassiterite in some of the 
claims in the Herberton district, as in the North Australian and 
in the Great Northern P.C. Soapstone has also been found in 
the Clifton colliery, on the Darling Downs ; at Kilkivan ; and in 
a rather indurated form of a yellowish green colour at Petrie’s 
Quarry, Brisbane. 
SERPENTINE—Comp. hydrous silicate of magnesia. 
Serpentine occurs in large masses at Gladstone, and at Ipswich 
it forms the matrix of chromite. Noble serpentine of a fine green 
colour is found in the Kilkivan district, but it is usually much 
jointed. 
Mr. Daintree, in a report on the Rockhampton mining district, 
describes a belt of serpentine which extends at intervals from 
Mount Wheeler to Marlborough. I have already under ‘ Gold” 
mentioned some of Mr. Daintree’s remarks on this subject (vde 
p- 37); he further mentions the occurrence of chromite and 
chromic ochre in this serpentine, and also the numerous outcrops 
of copper ore which have been discovered in this district. Mr. 
D’Oyley Aplin, in his report on the Burnett district, mentions the 
occurrence of serpentine on Sandy Creek, a tributary of Barambah
