TALCHEER COAL FIELD. 



Here, as indeed along the whole of the Southern boundary, the 

 unconformity is but slight, both series of beds having a gentle dip 

 towards the North. Over these white sandstones are seen greyish or 

 light brown felspathic grits, very false-bedded, not containing pebbles or 

 boulders. They frequently contain large irregular ferruginous concretions, 

 with a concentric structure, but no traces of fossil remains, either animal 

 or vegetable. (Fig. 9.) 



It is impossible to estimate, with even approximate accuracy, the 

 thickness of these beds, a,s for the most part they do not exhibit any planes 

 of bedding, and their mineral character varies but little throughout. 

 There is a good section seen in the bank of the Brahmini, below the 

 Eajah's residence at Talcheer, where they seem to be nearly horizontal ; 

 but as there is reason to suppose that they are here faulted against the 

 lower beds, probably this section, from which there should be assigned to 

 them a thickness of about 100 feet, exposes only a part of the series. 



Towards the upper portion, these beds acquire a very shaly character, 

 and closely resemble the highest beds of the group. 



There is a well-marked distinction between them and the beds 

 immediately overlying, which nevertheless rest apparently quite conform- 

 ably upon them.
