quartz reefs frequently occur which strike with the country-rocks, but dip 
across them for part of their course. Such reefs as occur at the Phoenix 
occupy lines of fault that strike with the beds, but that dip westerly. 
In part of their course they conform to the bedding planes of the country- 
rocks in dip. (See A.E., Fig. 18.) In part of their course they conform 
to the bedding planes on one wall, but cross them on the other wall —(See 
B.D., Fig. 18)—or they cut right across the bedding planes. (See C., 
Fig. 18.) 
Frequently the quartz reefs occurring in such faults are of large size,, 
and are often very productive of gold. Reefs of this class are common. 
They occur at Bendigo, Chewton, Castlemaine; at the Cumberland and 
Phoenix mine, Campbell’s Creek; at the Cornish mine, Daylesford; and 
many other places. 
Such faults in parts run with western country on both walls. The 
country-rocks are always dipping to west in such cases, and this class of 
fault may be termed western strike faults^ for they strike with the beds 
and dip to west. In such cases the reefs in them may easily be mistaken 
lor “ legs,” but they are only false legs, as there is no saddle reef attached 
to them, and they have quite a different origin.
