210 MINERAL CENSUS OF AUSTRALASIA. 
identification in 1885, and another from Tingha in 
1887, so that the mineral probably occurs in several 
localities (L.). 
GARNET (Rubicelle and Almandine),—Barrier Ranges, in schist 
and detritus, also in quartz obtained by diamond drill 
bore at Broken Hill; Monaro, with sapphires; (Geo. 
Sur, Dept. of Mines, Sydney).

Garnets occur in the New England district, on the 
borders of Queensland. These are the ordinary red 
garnets (iron-alumina garnet), but like those found in 
Queensland have been mistaken jor rubies. The 
Bohemian garnet, magnesia alumina garnet, is said to 
occur in large quantities near Maryland Creek, Co. 
Buller (L). 
Giaucopot.—Three-quarters of a mile south-easterly from Carcoar 
Railway Station, with erythrite, molydenite, and thin 
films of an apple-green to dark-green mineral, determined 
by Mr. J. C. H. Mingaye, F.C.S., to be annabergite. The 
ore, as far as at present proved, consists of a succession 
of lens-shaped bunches. The deposit of cobalt appears 
to have been formed in a line of fissure, which, for 
some distance, followed the line of junction of the 
diorite with the slate, and was probably directly due to 
the intrusion of the diorite, being formed either by the 
thrust of its upheaval, or by the contraction consequent 
upon the cooling of the mass of igneous rock. Towards 
its north-east end this fissure was partly filled by a 
dyke of fine-grained diorite, closely resembling the 
chlorite slate, which it has penetrated. The cobalt ore 
was then concentrated into the irregular hollows along 
this line of fissure by some process of segregation, for 
its intimate admixture with the dyke rock is difficult of 
explanation on any other hypothesis. Analysis made in 
the Department of Mines Laboratory by Mr. J. C. H. 
Mingaye, F.C.S. :—
