PecuKar fault. 



most remarkable circumstance^ however,, about the fault at Salbaldee is 

 that it is a reversed troug-h faulty for although the 

 two faults unite a few miles to the east and west, 

 so that they can only be considered as a part of one general fault, they 

 throw in different directions. Such a phenomenon can only be explained 

 by supposing that throws have at different times taken place along the 

 same line of weakness, but in different directions, up and down, and that 

 in this place the two lines have not exactly coincided, though elsewhere 

 they have. (Fig.' 7).

From the metamorphics, close to the fault at Salbaldee, a hot-spring 



rises, the temperature of which is 100° Fahr. The 



^ '^^" °' water is clear, tasteless and scentless. 



The metamorphics, as already stated, continue for only a mile or two 



in either direction from Salbaldee, and their breadth

clearly seen. Along the fault to the eastward, there 



is a mass of highly crystalline trap, resembling a dyke, and it appears 



probable that a dyke has been in places injected into the fault. Some 



dykes also cut through the sandstone. 



In the next valley^ to the westward, about 3 miles from Salbaldee, the 

 sandstone appears to be about 300 feet thick, and is 

 capped by the silicious limestone varying from 15 to 

 30 feet in thickness, and occasionally containing pebbles. Here also

 nearly the whole of the Poorua valley, are from Mr. Wynne's notes.
