at the rate of many thousands of gallons per day. Some of the 
limestones at Carawine have been faulted. (Fig. 21).

Fault in Dolomitic Limestone, near Carawine Pool, Oakover River, 
Pilbara Goldfield. 
At Irregully Creek, in the Ashburton River, the Carawine 
Dolomite Series, which in this locality consists of gently inclined 
flaggy limestones, rests upon a bed of conglomerate two or three 
feet thick, which in its turn reposes directly, and with a violent 
discordance on the older beds beneath. Near the mouth of Sol- 
diers' Secret Creek, another im]:»ortant tributary of the Ashburton 
River, the limestone which is at least M50 feet thick rests directly 
on the upturned edges of the schists and slates, which form the 
matrices of the auriferous deposits. No conglomerate was found 
at the base of the Niillagine Formation, as developed in the table- 
land which forms the divide between the watershed of the Lyons 
and the Gascoyne. 
What may possibly turn out to be the northern extension 
of the Carawine Dolomite Series is to be found in the Napier 
Range in Kimberley. (Fig. 22).
