Section 11. — Nerbudda Valley north of the river; from Chota 

 OoDiPOOR^ Panwud^ Kawat and Hamp on the east to the allu- 

 vial PLAINS of BaRODA ON THE WEST. 



In this tract;, as in the last described^ metamorphic rocks prevail to 

 General distribution of the north, traps to the south. The boundary of 

 ^°^^^- the latter to the westward turns rapidly south, 



while the cretaceous beds become largely developed. The country to 

 the north-west from Jumbooghora and Narookot to Champaneer and 

 Powagurh hill will be described in a separate section. 



The gneiss from Chota Oodipoor to Jumbooghora is the same grani- 

 toid, highly ciystalline rock which is found east of the first named place, 

 no trace of foHation in general being visible ; but where such can be 

 distinguished, which is very rarely the case, it has a tendency apparently 

 to a north-west- south-east direction. This tract deserves no especial 

 notice, and presents no character -of interest. 



A small patch of cretaceous beds intervenes between the traps and 

 the metamorphics close to Panwud. Thence to the west, for a long dis- 

 tance, traps rest directly on the crystalline rocks. 



The only interesting portion of this section is the southern, consist- 

 ing of trap, with some small but instructive inliers of cretaceous rocks : 

 of these a larger number doubtless exist than have been mapped, but it 

 is believed that aU of any size have been laid down. The traps of this 

 country are also very interesting, ash beds prevailing to a greater extent 

 than usual, and beds of unquestionably sedimentary origin, yet differing 

 from the lacustrine deposits of Central India, being intercalated in 

 places. 



There are two principal cretaceous inliers both close to Kawat. In 

 the more eastwardly of these a fair section of the beds of which it is 

 composed is seen in the Kurro stream, and will be detailed presently.
