than the lowest visible, which rests upon massive beds of the same 
rock below. 1 The exposed surfaces have been eroded in a remark- 
able manner by the atmosphere, and appear in the form of sharp, 
confluent, serrated ridges, grading downwards on all sides, 
the whole giving the effect of a model of mountain chains on a 
small scale. The rock decomposes comparatively readily, and 
produces a rich red clay soil. 2 The beds overlie unconformably the 
schistose Pre-Cambrian rocks on the east and west. ... In 
lithological characters, this formation is similar to that covering 
large areas between the Katherine Station and Flora Falls; also to 
that at Jasper and Timber Creeks, off the Victoria River : between 
the Elsey and Daly Waters Stations on the Transcontinental 
Telegraph Line ; at Anthony’s Lagoon, Brunette Downs, Alex- 
andria Station, and other places. It is most probably continuous 
beneath the basalt, sandstone, and other later formations. The 
occurrence of Cambrian fossils near the Daly River and Alexandria 
Station prove that these widely separated expanses of limestone are 
identical in age.” 
CONCLUSIONS. 
Hardman collected his Cambrian fossils : — 
At River bed (Elvire) South of Base Line Camp Z27 
(HB27). 
At river bed (Ord) 5 miles below its junction with the 
Elvire, opposite the Hill J38 (HB 48). 
And at Mt. Panton, Northern Territory (HB33). 3 4 
Mr. H. W. B. Talbot collected Cambrian fossils ( Salterella ) at 
the Homestead, Ord river Station. 
The stratigraphical results may be summarised as follows : — 
Cambrian rocks are exposed in Kimberley along the valleys of 
the Elvire and Ord rivers from near the North-western extremity 
of the Hardman Range to the Ord River Station, and so on to 
Mt. Panton (N.T.),< thence they will no doubt be found to 
1 This admirably describes the outcrop in the Ord River Valley, and at Mt. 
Panton. 
2 A marked feature round the Ord River Station homestead. 
s The " Limestone with Fish Palate,” is also of Cambrian age (posted p. 74). 
4 An outlier of carboniferous age as a capping to Mt. Panton would explain 
the presence of carboniferous fossils at that locality.
