20 JONES : SOUTHERN COAL-FIELDS OF SATPURA GONDWANA BASIN. 



distributed over the whole area and tend to form a covering represent- 

 ing to some extent the original form of the ground ; only in those 

 portions where the surface is too steep to allow of the material rest- 

 ing, will it more or less gradually subside giving rise to a disturbed 

 condition of the strata near those points. 



The three diagramatic sketch sections (on the small map) show 



some of these features. In order to exaggerate 



the surface profile, and give an idea of the hilly 



nature of the country which is not always well shown on the map, the 



vertical scale is twice the horizontal scale. 



§ 7. — The Barakars. 

 The Barakars in this basin are separated into several small areas 

 partly by the overlying trap and partly by faulting. Commencing at 

 the east we have : —

 This is an area of but small extent, being only 1 • 1 square miles. 



The name adopted is that of the small village

(E. Lon. 78 57 ) near which the coal occurs. 



This area is entirely surrounded by trap which forms a part of the 

 large flow extending to the east. The south boundary of the Bara- 

 kars is covered by trap, but in the north-west corner there are some 

 ferruginous shales and red clays exposed belonging to beds higher in 

 the series. Below the trap of the hill to the east of Sirgora, there is 

 a conglomeratic sandstone containing pebbles of red jasper and white 

 quartzite, and resembling a rock in much the same position further to 

 the east which is probably of infra or inter-trappean age.
