The sandstone overlies part of the mass of basalt “ which is found capping nearly 
all the higher ground of the district right away from the plains of the Darling Downs, 
near Laidlcy, Grandchester, Ipswich, Waterford, Mount Tambourine, on the dividing j 
ranges between the Logan, Albert, and Coomera Divers, and Norang, Mudgeeraba, f 
Talleobudgora, and Curambin Creeks.* It is also met with at Durleigh Heads, Cor- 
rumbin Heads, Point Danger’, and on the Maepherson Dange.” Mr. Dands informs i 
me that the base of the Desert Sandstone in this locality must be at least one hundred 
and fifty feet above the sea. 
In the Gympie District Mr. Dands describes the Desert Sandstone as follows : — 
“ This is a coarse-grained silicious sandstone, or freestone, which overlies the 
Gympie Beds [Permo-Carboniforous] in various places. The rock is made up of coarse 
granules of quartz. It lies horizontally, but nearly everywhere exhibits ‘false-bedding’; 
the true bedding of the rock can be detected by thin layers of coarse pebbles of quartz. 
A large outlier of this sandstone can be traced from Eel Creek, crossing the Mary near 
the Pishennan’s Bend, whore it forms high banks to the river. It has been quarried as 
a building stone near Eel Creek, on Mr. Dan. Henry’s Selection, No. 882, and it has 
been used in several of the principal buildings in the town. Outliers of this stone also 
occur a few miles north of Gympie, near the Maryborough and Gympie Dailway 
Line.” f Mr. Bauds believes the base of the Desert Sandstone to be here one hundred 
and fifty feet above the sea-level. 
Mr. Daiutree, in 1872, J referred to certain beds which “ crop out at the township 
of Maryborough, and have been used by the Corporation as quarries for road-metal,” 
and gave a list of fossils therefrom, as determined by Mr. Bobert Etheridge, P.D.S. 
These beds Mr. Daintree regarded as the upper portion of the Burrum Coal Measures, 
and occupying “ a position between the Gordon Downs and Pliuders Diver series.” 
More recent and extensive collections of fossils do not at all bear out this view, the fossils 
on the contrary bearing a very close correspondence with those of the Desert Sandstone 
at Croydon. Probably Mr. Daiutree made only a hasty collection of fossils, as he does 
not even give a descri])tion of the strata. 
Mr. Dands has within the last few years carefully mapped out the beds and 
shown their relation to the underlying Burrum Coal Measures. In his “ Deport on the 
Burrum Coal Pield,”§ he says, “ The Maryborough Beds have been quarried about one 
mile west-north-west of the Bailway Station by the Corporation for road-metal, and by 
the Government two miles further out in the same direction for railway ballast. The 
rock quarried is a fine-grained, light brown or grey sandstone. These beds contain 
numerous shells. 
“ At the Corporation quarry the strata consist of light-coloured, fine-grained 
sandstones, dipping 12° to N. 35° E. 
“ About a mile and a-hal£ further along the Gayndah Doad, and close to the 
Mary Diver, about half a mile from w’hat is known as tlie Copenhagen Bend of the river, 
is the first of the Government Quarries. The dip is about 7° E. The rocks showing 
are : — i

translation, is not universal. R.L. J.
