Mr. A. Gibl) Maitland speaks in the following terms * of a series of strata which 
he refers to the Star Beds : — 
“ It is with hesitation that I class a series of grits, sandstones, and conglomerates, 
occurring in the south-east corner of the country, with the Star Beds. No organic 
remains were detected in any of them. . 
“ It is only their strong lithological resemblance to strata of that age in o er 
areas that gives any clue to their geological position. They do not occupy a very 
extensive tract of country. r. t-x, t- 
“ The first locality in which these beds were met with is about north-north-east 
of Kangaroo Hills Station, and distant about eight to ten miles. ^ They consist of coarse 
whitish quartzose grits and conglomerates, lying almost horizontally and orming 
conspicuous escarpments, traceable for some distance ; they rest alternately upon 
granite and the upturned edges of a series of hardened grits and shales, which have a 
general north-east and south-west strike. Sect. IV., plate l,t gives a general idea o 
their occurrence. Some little distance from Mount Fox to the north, about ten ce 
thick of a whitish quartzose grit resting on granite and dipping at 70 N.E., is seen o 
be overflown by sheets of basaltic lava. Much lower down the creek boulders of grit 
were seen, but this is the only section where the rock is met with in situ. The section 
is shown Sect. I., plate 2. . -r> i • u 
“ An extensive devclojiment of these beds is to be seen in the Blue Kange, 
occupies that piece of coimtry drained by the tributaries of Tomahawk or Packsaddle 
Creek, Camel Creek, and some minor affluents of the Burdekin. In a traverse from the 
camp on Tomahawk Creek to the Blue Eangc the country was found to consist of shales 
and ferruginous felspathic sandstones or greywackes, in which no fossils were detected. 
These beds are nearly vertical, and strike north-cast and south-west. 
“ The sedimentary strata which rest unconformably upon the vortical beds are 
arranged in the form of a synclinal trough, the longer axis of which appears to trend m 
a north-westerly direction. Scaling the first cliff formed by the denudation of the Star 
Beds, the quasi-vitreous white sandstones were found to dip S. at angles of about 3.j , 
the trend of the mural precipice was east-south-east. The actual summit was ascertaiue 
by Aneroid to be 2,030 feet above sea-level. This mountain is almost isolated from the 
main mass of the range by a low saddle 1,620 feet above sea-level, and which divi cs 
waters flowing east and west. In this low saddle vertical ferruginous felspathic grits 
striking north-east and south-west crop out at intervals. After passing over a 
table of grit, beneath which the vertical sedimentary beds arc seen to lie, a hill 1,930 
feet above sea-level was ascended and found to bo capped with grits, which were seame 
in places with veinlets of quartz. At the foot of the hill in the north-east these be s 
appear to be faulted against the vertical shales and greywackes. The highest point o 
the range was found to be 2,670 feet in height, and composed of coarse grit and 
conglomerate, with a vertical waU-like precipice over 100 feet in height facing the south- 
west. (Section II., plate 2.) 
“ From this point the general character of the range could be well seen, and its 
geological structure. Owing to darkness coming on, I was unable to visit the south- 
westerly end of the synclinal trough. . . a i> i 
“ Another minor area of what are regarded as representatives of the otar Beds 
is met with in the vicinity of Lake Lucy Station. Some distance west from the bead 
station a conspicuous low hill is seen to be composed of a semi-vitreous white grit or 
quartzite, which appears to unconformably overlie the 'Wairu na Beds.
