AURUNGA FIELD: BARAKAR GROUP, 59 



belt strikes ia a south-westerly direction from Oopag for about 2J 

 miles towards Huratu. It is well exposed in section in the Jelma river, 

 and consists of shales, sandstones and a strongly-developed boulder bed. 



These in places are a good deal disturbed and crushed, but I saw no 



clear indication of any faulting having taken place. 



The second outlier is situated to the north of Nowagarh. The 



^ ,,. J. 1, £ character of the Talchirs here is best seen in a 



Outlier north or 



Nowagarh. section which is exposed for about half a mile in 



the bed of the Sotapani between the villages of Kotilwa and Heslah. 

 The rocks chiefly consist of soft yellow sandstones, which rather closely 

 resemble those of Raniganj-age, and yellow shales. At Topo, and thence 

 eastwards, they are covered up by the pebble conglomerates, and are 

 overlapped by them, as they do not reappear along any other part of the 

 boundaries of this outlier. 



Section 2. — Barakar Group. 



The rocks of Barakar age within the limits of the Aurunga field 

 occupy several practically detached areas (the intervals being covered 

 by younger rocks) which can be most conveniently described separately. 

 These areas, therefore, will be taken up as they occur from east to west, 

 or as they would be encountered by any one entering the valley of the 

 Aurunga from Balumath. The shape of the first of these, which lies 

 on the north-east, and from which a prolongation margins the field 

 on the north, is too irregular to be intelligibly described, but with the 

 accompanying map before the reader any such explanation is scarcely 

 necessary. 



The first section to be described is that which is exposed in the 



e ,. . ,, northern branch of the Sukri south of Balu- 



Section in northern 



branch of Sukri. naggar. Already the character of the beds seen 



at the road-crossing has been alluded to in describing the Talchirs. The 

 conglomerates and white and pinkish clays extend thence eastward into 

 the highlands where, in the neighbourhood of the already-described 

 ridge of fault rock at Korean, they are locally much disturbed, dipping
