coloured shales, sometimes jasperised, together with grits, groywaches, and quartzites 
generally inclined at high angles. The thickness of these beds, unless repeated hy 
folding, must be very great. 
“ From their lithological characters it appears possible to divide them into two 
subdivisions, one consisting for the most part of reddish shales and ferruginous 
chocolate-coloured sandstones, and the lower ol; dark shales, grits, and greywaekes. 
From the fact that these reddish hods were first seen near AVairuna Station, for 
convenience of description I have named them the Wairuna Beds. 
“ From the Four-mile Creek — a tributary of the Douglas — to Kangaroo Hills 
Station the gullies show bulf-coloured vertical shales and greywaekes, striking generally 
east and west. 
“ The eastern bank of the river at Kangaroo Hills Station is composed of buff 
shales and greywaekes, which dijo at an angle of 80° N. 70° AY., and strike K. 30° E. 
“ Near the tin lodes, the ‘ Star Beds ’ are seen to rest upon a series of highly 
inclined hardened grits and shales. In close proximity to the granite, bods hardened 
and metamorphosed are met with ; to ascertain whether these are representatives of the 
Burdekin Beds more highly altered, or are of older date, would require much more 
detailed work than is possible in a fiying reconnaissance. 
“ From Kangaroo Hills Station to the mouth of Camel Creek the country is 
occupied by vertical shales of a somewhat similar type to those above described. In 
Tomahawk Creek they strike AY. 20° S. Between this point and the crossing of the 
Douglas the sedimentary strata are intersected by a tongue of granite. 
“ From the mouth of Camel Creek to a gully about 2 miles further down the 
river the country is made up of vertical contorted shales and greju'ackes ; at the south 
end of the section their strike is north and south, at the mouth of Camel Creek it has 
veered round to west-north-west. 
“ A few low hills of flaggy grits, dipping at angles of from 25° to 30° to the north- 
wards, are passed over in traversing the country from the mouth of Camel Creek to a 
point on the opposite side of the Burdekin to Greenvale Station. 
“To the A^alley of Lagoons Station comparatively few sections are to be seen, 
owing to extent of flat country covered with recent superficial deposits. At one place 
about 5 or 6 miles north of Greenvale Station, ridges showing vertical sandstones 
striking north-east and south-W'est occur. These bear a strong lithological resemblance 
to those last described. Similar beds underlie the flats for the next few miles, then their 
place is taken by reddish jasperised shales. The relation of these shales to the sandstones 
is not very clear, but I am inclined to regard them as being separated by a fault. 
“ Further northwards along the road the eye is attracted, even at a distance, by a 
conspicuous cliff about 100 feet in height. On nearing it the western face was found 
to be full of caverns of no great size, and the base was strewn with huge boulders of 
rock. The matrix of which this hill is composed is a quartz rock generally with a 
reddish tinge, though sometimes white. It appears to be bedded, the bedding planes 
being nearly vertical and striking north and south. Some of the weathered surfaces 
suggest a volcanic origin (ash ?). 
“ Underlying the flats of the next mile or two are shales, &c., dipping at 25° to 30° 
to the north-east. 
“The country to the east of the station at the Valley of Lagoons is occupied 
by fine-grained sandstones of a yellowish-brown or buff colour. In some places the 
sandstones are crowded with sun-cracks. They rest unconformably upon the schists, 
and dip to the south-east at angles varying from 70° to 30°. They do not form any 
important feature in the landscape.
