52 eoote: geological structure of the eastern coast. 



Sandstone, whitish-grey. 



Ditto, grey.

Ditto, micaceous, pinkish-brown. 

 Grit, shaly, dark purple, ferruginous. 

 Gneiss. 



These beds roll about a good deal, and are locally often obscure, besides 

 showing false-bedding, but the general dip is westerly at a low angle. 

 A large mass of silicified wood was observed in one of the beds at the 

 top of the series, but no other fossils were found in this section. 



A couple of miles south-west-by-west from Ramnaickenpett, at 

 the village of Pedda Pamidi (Pedda Powenny), 

 tion. drab friable sandstones are exposed to a depth of 



15-16 feet in well-sections, under several feet of kankar and lateritic 

 gravel. Separated from these sections by about half a mile of alluvium, 

 is a fair section exposed in the right bank of the Vupput-eru, at its 

 junction with the Mutialpad nulla. The succession of beds is not 

 very clear owing to the broken nature of the bank and to the want of 

 definition of the several beds, which have a tendency to graduate one 

 into the other. The beds, which have a general north-westerly dip, 

 never exceeding 8° and generally much less, succeed each other in 

 the following order : — 



Sandstone, shaly, Indian red and drab ... ... V 



Ditto, drab ... ... ... 1' 



Ditto, shaly, drab and Indian red ... ... 0' 8" to 0' 10" 



Ditto, ditto in parts, mottled red and brown ... 2\' to 3' 



Ditto, ditto, Indian red and drab ... ... 3 A to 4' 



Some 6 miles to eastward of this last section is a low rocky bluff, 

 p ,, , . „ consisting of coarse gritty conglomerate and sand- 



stones, rising out of a jungly plain and lapped 

 round by laterite gravel. This bluff is formed by a small remaining patch 

 of Rajmahal rocks resting on gneiss, which shows a very little distance 

 to the south : the conglomerate and sandstones are of no great thickness,
