KHASI HILLS

ft. in. 

 Sandstone, thin shaly beds with carbonaceous parti- 

 des, giving a blackish-grey colour to the rock ; 



beds very irregularly developed 1 to 2 



Ferruginous sandstone 3 



Thin-bedded earthy sandstones 1 to 2 



Sandstone, hard, ferruginous, and earthy, very irre- 

 gular and varying from 3 to 6 



Limestone (as described above.) 



The coal seen in the foregoing section becomes in the lower part of 

 the bed very shaly, and passes into the grey shale 

 on which it rests. A little to the South of this 

 section (which is taken just above the cliff of limestone facing the 

 station of Cherra), this thick bed of coal, which is here of uniform 

 quality throughout, becomes split up by several small intercalated 

 layers and wedge-shaped masses of sandstone. These gradually increase 

 to the detriment of the coal, and shortly after the coal has died out 

 altogether. In the coal itself iron pyrites occurs, disseminated and in 



Character of coal beds.
