SOUTHERN COAL-FIELDS OF EEWAH GONDWANA BASIN. 



The contacts of the group are almost all original ones, hut there 



are a few small faults, the most noticeable being: 

 Fault. Bamhani Cbilpa. & 

 the one south of Bamhani Chilpa, where there are 



two inliers of Talchirs. 



The thickness of the Talchirs, where most freely developed, appears

however, were obtained, which Dr. Feistmantel has noticed in Vol. IV

SECTION VI. — BARAKARS. 



There is satisfactory proof of the occurrence of this group over a 

 large portion of Rewah, Korea, and Jhilmili in the strong resemblance 

 that its sandstones and other rocks bear to the typical representatives in 

 the Raniganj field. Included with it are the beds containing a flora 

 which partly coincides with that of the Karharbari group. I saw no 

 reason, however, either on stratigraphical or litho- 

 logical grounds, for separating them from the Ba- 

 rakars, and consequently I have not mapped a line of demarcation. This 

 may be a misfortune, so far as it fails to be in harmony with the restricted 

 application of the palaeontological facts, but as the wider bearing of the 

 evidence demonstrates a closer knitting of all the groups than has hitherto
