DAMUDA SERIES : BARAKARS. 47 



the Bokaro. Its thickness is nine feet. The beds dip steadily south. 

 As we go up the nullahs two more seams are met with, and then some 

 carbonaceous shales with ironstones. A reverse dip takes place in these 

 beds, and then the section is in descending order. Local dips are seen 

 in this area similar to those in the Bugjobra. 



West of Gosee and north of Boharo. — There is a small river 

 west of Gosee, known by the same name (Bhagalatta) as the one which 

 unites with the Chootooa near Layeo. In it there are some seams, and 

 a dyke is also seen. There is ample evidence of a series of faults 

 varying in direction from north to north by east. They are not of 

 great throw, and are not of much interest except as indicative of an 

 area of weakness. Towards the source of this stream, the middle 

 division of the Barakars is well exhibited, and the deep yellow iron- 

 stones of that group crop out on the surface in great abundance. 



Boundary north of Juggaysur. — The boundary north of Juggaysur 

 is undoubtedly a natural one, and the regular pebble beds of the Bara- 

 kars are excellently developed. Several runs of quartz breccia and granite 

 occur ; indeed the great number of the latter is quite a feature in the 

 district. 



Underlying the Barakars, along many portions of the boundaiy, is 



a very compact reddish green siliceo -ferruginous 



rock — that is probably gneiss, which has been 



impregnated to a considerable extent by the elements forming the 



sedimentary rock. It has very much the appearance of Talchirs. 



SeerJca Nullah. — I did not take the trouble to measure the section 

 in this river. I merely noted that coal occurred near the boundary dip- 

 ping at 5S° to the north, and that at its mouth the coal inclined towards 

 the north-west. 



Jheerna or Pindra Nullah. — In the neighbourhood of Jheerna there 

 are so many rivers to choose from in which to make sections that it 

 is difficult to tell which one to go up. I have, however, chosen to follow
