Art. V. — :0n the Occurrence of Three Bands of Marble at South Peak, 



near Hampden, Otago.

In the early part of last November, while investigating the extension of 

 the Shag Point beds to the landward side of Hampden, I was informed by 

 Mr. A. Craig, of that place, that an attempt had been made some twenty 

 years ago to burn limestone in a kiln somewhere near the upper end of 

 Baghdad Road. As the result of two days' search, with the assistance of 

 Mr. Craig, I found a small outcrop of a grey crystalline limestone on the 

 north side of Skinner's 

 Creek, at an altitude of 

 450 ft. above the sea, at 

 a point about 300 yards 

 from Baghdad Road. 

 The outcrop had been 

 opened out by blasting, 

 and I concluded that this 

 was the place from which 

 the material for the ex- 

 perimental burning had 

 been excavated. I con- 

 tinued the search towards 

 South Peak, and suc- 

 ceeded in discovering 

 three well-defined bands 

 of limestone, two on the 

 south side of Skinner's 

 Creek and one on the 



north. These bands are interbedded in the altered argillite that forms the 

 core of the coastal range lying behind Hampden. They strike almost north 

 and south (true), and dip east at angles that vary from 50° to 65°. 



Band A is about 5 ft. thick ; band B, 12 ft. ; and band C about 2 ft. 

 Bands B and C are separated from one another by 32 ft. of argillite. 

 Band A, geologically the lowest, is perhaps 200 ft. below band B.
