56 KING : COASTAL REGION OF THE GODAVARI DISTRICT. 



With these upper clays are seams of brown and pink ferruginous sand- 

 stones. There may be 150 feet of these less compact sands and clays, 

 as made out from the plateau hill south-east of Rajahmundry. 



These are succeeded by heavy and coarse dark-brown, nearly black, 

 thick-bedded sandstones, occasionally quite vitreous and not unlike quartz- 

 ites. The coarser beds are made up of fine angular grains of clear 

 glassy quartz, dirty quartz, and jasper clay -ironstone, cemented by dark- 

 brown peroxide of iron. With these are also seams of hard scabrous 

 (lateritoid weathering) ferruginous sandy indurated clays. It is in this 

 band that the Dowlaishweram quarries have been worked, and it forms 

 the cappings of some of the small plateau hills east and south-east of 

 Rajahmundry. The long south-east slopes of the quarry hill north- 

 east of Dowlaishweram are made up of brown ferruginous sandy indu- 

 rated clay beds. The thickness of the band is, at the greatest, about 

 30 or 40 feet. 



Over this, again, was a further good thickness of white and purple 

 mottled and red soapy clays, with brown and pink sand, which only 

 remains now as outlying hills and plateaus east of Dowlaishweram, as 

 at Razalu hill, &c. On the top of this hill there are soft friable 

 pale-brown coarse ferruginous sandstones. The long southerly sloping 

 plateaus, with headlands to the north, in the direction of Kuddum, have, 

 in addition to this capping of sandstones, another of lateritic sandstone 

 or laterite, which may, however, be of somewhat later age. 



We have, thus for the Rajahmundry sandstones at their thickest, 

 the following series in descending order : — 



4. Upper white and red clays and sands, with capping of soft 



reddish and Drown sandstones, about . . . 100 feet. 



3. Thick-bedded brown, occasionally quartzitic, ferruginous 



sandstones of Dowlaishweram hills, about . . 30 „ 



2. Intermediate soft soapy clays and thin-bedded friable sand- 

 stones ....... 150 „ 



1. Heavy conglomerates and reddish felspathic sandstones of 



Rajahmundry town ..... 100 „ 



300 or 400 feet.
