6. Shales. 



7. Thick-bedded sandstone. 



8. Shaly micaceous sandstone, 15° south-east. 



9. Soft unevenly bedded calcareous sandstone, with gritty beds. 



10. Shales and shaly sandstones. 



11. Thick mass of false-bedded sandstone oveiiappng locally the series below. 



12. Shales and banded sandstones, 5° south-east. 



Fault. 

 Thick bed of sandstone. 



Fault. . 

 Beds are here much disturbed, and the dip changes gradually to east 

 and north-east, and finally to north, at 38°, when we find in descending 

 order : 



Banded sandstones and shales. 

 Soft sandstones. 



Fa7ilt. 



Same beds as above : 



1. Sandstone. 



f Grey conchoidal shales, bituminous, with banded micaceous and ripple- 



I marked sandstones, dip 15° north, with — 



2. i Grey clay shales (near junction with Balsotha nullah, dip 8° uorth- 

 I east. 



l^ Banded micaceous sandstone. 



3. Shales with Coal. 



The whole series is, however, very much disturbed and shattered, and 



further on it appears that the same group of shales and sandstones are 

 several times repeated. 



The oblong expanse of Barakars mapped between the Balsotha 

 nullah and the Pipra hills offers only a few exposures in the shallow 

 nullahs. At several places south of the Pipra hill, fig. 1, Plate 5, and 

 again near Maihewa, Barakar shales, with traces of leaves, are unmis- 

 takeable, but the remainder seems to be mostly fine-grained sandstone of 

 Barakar type, traversed in several directions, as already described, by trap 

 dykes, which have altered the neighbouring shales into a brick-like rock. 



The faulted boundary with the Mahadevas is well seen south of 

 Hargaon and of Gurmuti, where a fault-rock similar to the one described 

 from the Garia nullah forms a high dividing ridge between the two 

 groups.
