COUNTRY NORTH OF THE SON AND WEST, ETC. 159 



Ginaor. — There are two little hillocks at the foot of the Kaimur 

 scarp by this village. At the eastern extremity of 



Ijinaor. . 



the western hillock is exposed a gentle anticline 

 formed by sandstone (Kaimur), in the centre of which is seen a dark- 

 ish grey sub-porcellanic rock exactly like that observed in the western 

 parts of the area under notice between the Rohtas limestone below 

 and the Kaimur beds above. This sub-porcellanic shaly rock passes 

 up into a light grey laminated soft shale which is overlaid by the sand- 

 stone forming the top-beds of the anticline. This sandstone is the 

 continuation of the lowermost beds of the sandstone exposed on the 

 adjoining Kaimur scarp. The Rohtas is not exposed here, but there 

 is little doubt but that it comes in just below the sub-porcellanic shaly 

 beds. Thus all that we can see here is that the sub-porcellanic sili- 

 ceous shaly rock passes up into a soft light grey shale which in turn 

 seems to pass up into the sandstone of the Kaimur scarp. 



Hillocks by Tikat* — There are three little hillocks here at the foot 



of the Kaimur scarp. Rising as they do from 



the alluvium of the plains, these hillocks are 

 seen to be composed of sub-porcellanic siliceous shales which are well 

 exposed on their southern slopes and are capped by thin-bedded sand- 

 stone. No marked thickness of the laminated soft shales occurs 

 here, but the siliceous shales seem to be immediately overlaid 

 by the sandstone. The uppermost shaly rock does not seem to be 

 an admixture of argillaceous and arenaceous materials, but while the 



shale is exceedingly fine-grained and seems 



Absence cf true pas- 



sage of mateiiai, but argillaceous (though may be somewhat siliceous), 



beds parallel. 



the sandstone seems entirely arenaceous and is 

 not very fine-grained. Thus there appears to be here an absence 

 of a true passage of material from the one set of beds into the other. 

 But though this is so, there is a perfect parallelism of bedding 

 between the shales and the sandstone. The Rohtas below the sub- 

 porcellanic shales is not exposed here. 



Baghawa* — The foot of the scarp-slopes north-west of Baghawa 



exposes sections exactly similar to those near
