88 VICTORIAN MINERALS.—CASE XV. 
15. ARRAGONITE. Map No. Mu 13. 
Tunnelling Co.’s Lease, Lisle’s 
Reef, Mount Tarrangower. 
4 sheet 14 S.W. 
On metamorphic sandstone. 
16. DOG-TOOTH SPAR. 
Degraves’ Mill, Kyneton. 
In basalt. Similar to No. 12. 
16a. CALCITE. 
Geelong. ’ 
Light yellow, acute rhombohedrons, 
coating limestone. 
17, FRESHWATER LIMESTONE. 
Map No. Ra 1. 
Muchleford Creek, lot 4, section 4, 
Strangways. } sheet 15 N.E. 
Containing cavities filled with fine 
crystals of “arragonite” and “calcite.” 
The former are especially characterized 
by fine terminal planes, which are seldom 
found on those occurring in the basalt, 
174. CARBONATE OF LIME. 
Guildford. 
Mammillary coatings of cavities in 
the basalt. 
18. CARBONATE OF LIME. 
‘ ; Map No. Ra 37. 
Police Reserve, Kyneton. 3 sheet 
9 S.E. 
Coating “hyalite” in mammillated 
crusts, filling cavities in the basalt. 
19. CALC-SPAR. 
Phillip Island, Western Port Bay. 
In older basalt. 
20. LIMESTONE. Map No. R 130. 
Section 46, Redesdale. 4 sheet 
13 N.E. 
Occurs in lumps and horizontal veins, 
in a red-and-yellow mottled clay, full of 
ironstone pebbles, under 8 feet of basalt, 
and overlying grey, cellular basalt. It 
is nearly. pure, and burns and slakes 
well, but is not abundant. 
21. CALCAREOUS DEPOSIT. 
Map No. M 41. 
Stone-jug Creek, Spring Plains. 
3 sheet 13 N.E. 
Occurs, underlying the basalt, in a bed 
a few inches thick, formed apparently 
by infiltration or absorption of carbonate 
of lime into the vegetable tissue of a 
moss, and the subsequent decomposition 
of the moss leaving the carbonate of lime 
in its exact form. It is a beautiful object 
under a strong magnifying power. 
22. CARBONATE or Lime Crys- 
TALS. 
OARS Keilor. 4 sheet 
Coating basalt, 
_ 23. CALCAREOUS Deposit. 
Map No. M 28. 
Near Peevor’s Station, Langley. 
i sheet 9 N.E. IAH 
Occurs in cakes from 1 to 2 feet thick, 
overlying a porphyritic dyke (in the bed 
and banks of a tributary of the Cam- 
paspe), from the joints of which bubbles 
of carbonic acid gas are constanly rising. 
23a. CARBONATE or Lime and 
MAGNESIA, with HYDRATED 
SESQUI-OXIDE or IRON. 
Deposited bya mineral spring (Seltzer 
. water) near Ballan. 
24. LIMESTONE. Lab. No, 2, 3/7/65. 
Cliffs at Curdie’s Inlet. 
White granular powder, containing 
84 per cent. of lime. An analysis by 
Mr. J. Cosmo Newbery gave the follow- 
ing results :— i 

Carbonate of lime ... 84438 
Carbonate of magnesia trace 
Carbonate of soda... 174 
Sesqui-oxide of iron ... 2'93

25. MacnesirE (Carbonate of 
Magnesia). List No. Mu 10.’ 
Lot7, parish of Tarrangower,near 
l- Loddon River. 
Occurs in nodular masses in surface 
drift. These nodules, on analysis, are 
found, not to consist of pure carbonate 
of magnesia, but to contain small and 
variable quantities of the carbonates of 
lime and iron, with a little clayey matter. 
Magnesite has lately been profitably 
employed by the “aerated bread” com- 
panies, for the production of pure car- 
bonie acid gas, and is likewise in 
demand for the manufacture of “fluid 
magnesia,” 
26. Brown Limestone (Marble).
