West of the Gunnoorgurh spur, the plain north of the river is 

 Country west of Gun- mainly covered over by alluvium. To the north the

The country is geologically very uninteresting as far as the neighbour- 

 hood of Hui-rungaon. South of this place metam-

orphic rocks emerge here and there from, beneath 



the alluvium. They are granitoid in places. Patches of overlying trap 

 rest upon them, and a considerable thickness of alluvium conceals the 

 greater portion of the rocks. 



West of Hurrungaon are two hillsj conspicuous from a distance. 

 Hills of quartzite west Composed of very massive quartzite, of peculiar

or, perhaps, Bijawur. The connexions, however, were not made out. The 

 accompanying sketch (Fig. 1, PI. VII) illustrates the appearance of one 

 of these hills formed of white granular quartzose rock, that furthest 

 to the west, near the village of Sagonia. The other sketch (Fig. 2) 

 illustrates the contrast afforded by the outline of the trap hills. 



On the Bhowra ghat by which the scarp of the Malwa table-land is 



ascended, north of Hm-rungaon, there is far less

appearance of bedding than is usual in the traps 



of the -Malwa plateau, especially further to the west. The basalts are very 

 columnar, a character which is common in the lowest beds of the traps 

 in this part of the Nerbudda valley. 



Metamorphic rocks appear in force about Kunnod. Much granitic 



Metamorphics near and syeuitic rock is associated with them. Crys-

 The remainder of this tract was only very cursorily surveyed by Mr. Wynne, whose instruc- 

 tions were limited to laying in the boundaries of trap, Vindhyans and Metamorphics. 

 It has since been examined more closely by Mr. Mallet, whose observations will be published 

 separately.
