MINERAL CENSUS OF AUSTRALASIA. 
Goxtp, Narive! ! !—The geological distribution of gold in South 
Australia is restricted to the Pre-silurian, certain gravels 
of the Miocene period, and to drifts of later age. In 
the first it occurs disseminated in veins of quartz; in 
the second and third cases as alluvial gold (Tate) ; 
the following are some of the localities in which gold 
has been found in one or other of the conditions named 
above :—Onkaparinga River, South Para River, Torrens 
River, in sand (T.C.C.); Bremer Range, Barossa 
Range, Nairne, Woodside, Strathalbyn, Mount Barker, 
Clarendon, Noarlunga, Currency Creek, Mount Pleasant, 
Jupiter Creek, Echunga (T.C.C.) ; Ulooloo, Waukaringa, 
Bigg’s Flat, near Echunga ; Balhannah Mine, associated 
with native bismuth and bismuthinite ; Teetulpa, Mount 
Ogilvie, Lady Alice Mine, with bornite; Moonta 
Mine, with bornite (T.C.C.); Bird-in-the-hand Mine, 
Echunga Mine, Fountain Head Mine ; Kangaroo Mine, 
near Oakbank, in psilomelane; Mount Victoria, with 
copper ore; Yudanamutana, Mount Wells, N. T., Old 
Blackfellow’s Reef, N. T. (Brown). In the Northern 
Territory gold is widely distributed over that portion of 
Arnheim Land occupied by metamorphic rocks. The 
fields extend from the River Stapleton to the Driffield. 
The chief centres of gold-reeting are the Howley, Twelve 
Mile, McKinlay, Union, and Pine Creek (Tate). 
GRAPHITE !—Warrow, County Flinders, and one or two places on 
Gypsum ! 
west coast of Spencer's Gulf (T. C. C.); Mount Charles 
(G. Francis) ; Mount Torrens (C. Thomas) ; Belvidere 
Range, and about 23 miles N.E. of Adelaide (T. Burr); 
Blanchewater (Professor R. Tate) ; Hundred of Koppio 
(Government Geologist, H. Y. L. Brown). 
!!_Selenite is frequently met with in the form of 
isolated lenticular-shaped crystals, imbedded in the 
mud of the salt lakes, notably those of Southern Yorke’s 
Peninsula. It also occurs massive in the salt lakes 
(Cloud) ; Wailaroo Mine, Hummocks Range, Kanyacka, 
Kapunda, near Point Riley, Yorke’s Peninsula, on the 
Wirryalpa Run, Central Australia, Stuart’s Range, 
Central Australia: satin spar (T.C.C.); Lady Alice 
Mine (Tate); cliffs of River Murray (Tate) ; near the 
Springs at The Peak, Central Australia, with red 
ochre (Tate); N.E. shores of Lake Alexandrina, in 
curious rock form, composed of slightly coherent grains 
(Tate); Beltana Mine, in veins (Ulrich); Brighton 
(Burr) ; Burra Burra Mine, with malachite (T. C. C.) ; 
near Kadina, in form of fine powder like flour, under 
the microscope each grain shows as a distinct crystal
