DAMUDA SERIES : BARAKAKS. 31 



nullah gneiss occurs. Further up the stream pebble beds are visible, 

 forming a natural junction, although they are highly inclined. Some- 

 what north of this a change in dip is observable, and a coal seam that 

 occurs is very much crushed. A fault line probably exists, which, I 

 am of opinion, is the continuation of the one south of Loogoo Hill. 

 The similarity of phenomena in this nullah and the Dhungadhugwa 

 Nuddee is a noteworthy circumstance, namely, a sharp change in the 

 direction of dip. - ^ 



North-east of Sobang a tributary of the Koonar exposes five 

 Coal north-east of So- seams. The largest is 16 feet, and it occurs highest 

 ^°^* in the series. 



Nearly north of Banddeeh, in the Bokaro Nud-

dee, a small seam occurs, dipping at a high angle. 



Very little coal is exposed between Goomeea and Loogoo HiU, and 



none of any value. A very thin bed crops out in a nullah east of Ooda. 



An imperfect section of the Barakars is seen in the Bokaro west of 



Koyeeotand,
