to 8. Several shafts have heen sunk between the two faults, hut apparently to 
no purpose, as the horizon of the strata met with was probably not recognisable owing 
to the coming together of the two faults. 
North of this area the upper limestone is again seen with its normal strike from 
south-east to north-west, and a dip of 21“ to 23° to N.E. Mr. Bands has mapped it 
from this point continuously to a point about three-quarters of a mile east of O’Leary’s 
Crossing of the Mary Biver on the Elkivan road. 
“ A verv cursory glance is sufficient to show that” [at the Two-Mile] (see PI. 
58) “ we are dealing with very similar beds” [to those of the Central District, Gympie], 
“ while a closer examination shows that the order of superposition of the principal beds 
is the same in both places, and that the strata of the Two-Mile are an actual continuation 
of the Gymjtie Beds.” * 
“ The strata dip to E.N. B. at an average of about 20°. [&6 Section AB, PI. St, 
55.] Beneath the thidt mass of shales which lie away to the east we have, as 
on Gympie, the bed of impure limestone, here about 150 feet thick. Immediately 
below’ this is the bed of coarse pebbly conglomerate, with some thin beds of sand- 
stone. Below this again can be seen the outcrops of shales with beds of laminated 
sandstone— the equivalent of the ‘ Upper or Phoenix Slates’; then, at some distance 
below this, is the greenish and highly fossiliferous sandstone, identical with and contain- 
ing the same species of fossils as the bod which, on Gympie, is traced from White s 
Gully to near the Lucknow. A few feet beneath this is the ‘ Pirst Bed of blate a bed 
of black graphitic shale about 20 feet thick. The Hibernian and Homeward Bound 
Beefs were worked in this bed, and rich but patchy deposits of gold were obtained. 
About 150 feet below this is the ‘ Second Bod of Slate,’ about 15 feet thick, which has 
been worked in the Bristol and London Claims. Between these two beds are altered 
greenish groywaekes, one of which is an altered volcanic ash. It is made up of a number 
of angular particles in a fine matrix. There is also a peculiar grit or fine conglomerate, 
made up almost entirely of rounded and flatlened particles of about the size of peas. 
Below the Second Bed "of Slate is a hard crystalline ‘ greenstone’ of a similar character, 
and occupying the same position as on Gympie ; then below are altered greenish 
chloritic rocks, with an amygdaloidal volcanic rock (amygdaloidal diabase). At a depth 
of 5.30 feet below the Second Bed is the fine laminated greenish-grey greywacke, with 
which is associated the black shale known as the ‘ Third Bed of Slate, precisely similar 
to that met with in the Ellen Harkins, &c. Good gold was got in the Chatsworth Beef 
in this bod close to the surface, and the London shaft was in it from 63L feet to near the 
bottom (736 feet), when they passed into green chloritic rocks again. On comparing 
this section with that from the Bailway Station to Channon-street Bridge, their close 
agreement will be noticed. The Two-Mile can without hesitation be pronounced an 
actual continuation of the Gympie auriferous belt. 
“ The Two-Mile is situated some distance further away to the west than it would 
have been had the Gympie Beds continued without any disturbance. The large fault, 
however, which occurs between the two places has brought about, on a still larger scale, 
a repetition of what has taken place between the Smithfield and Phoenix Claims. The 
fault shifts the outcrop of the limestone and other rocks to the west for a distance of 
nearly 70 chains, which, allowing for a dip of about 1 in 3 to the east, gives a downthrow 
to the north of about 1,200 feet. 
“ The gold in the reefs at the Two-Mile is in rich patches, and not so continuous 
as oil Gympie. This may be owing to the country, which is reported to be much 
*Mr. Randauses the term “ Gympie Beds ” in the restricted sense of the auriferous strata of the 
Central District, Gympie.
