Sec, 10.] DETAILED DESCRIPTIONS. 145 



There is but one more place to the westward where Bijawurs are 

 met with in the Nerbudda valley: this is near Jobut; the description 

 will be found below. 



Section 10. — Nerbudda valley north oe the river^ from the 

 Baghnee rivee to Chota Oodipoor. 

 From Bagh to Chota Oodipoor the surface is principally formed of 

 metamorphic rocks occupying the area between 



rocks"^"^^^ ^''*''''°''*''''' °^ *^^ *^^P plateau of Malwa (which ends by 

 sinking into the plain near Kunas and Bhabra) 

 and the great trappean area to the south. The metamorphic country 

 is an extensive undulating plain with only occasional hills^ more or less 

 isolated, of granitoid forms of the gneiss. The trap country to the 

 south is very hilly, and it appears singular that the river should traverse 

 it in preference to the broad plain of the metamorphics. The traps 

 come in south of AUee and Panwud with a sharp southerly dip, which 

 fully accounts for the entire disappearance of the older formations 

 beneatb them. 



The sandstones and limestones of the cretaceous rocks intervene 

 generally between the traps and the metamorphics, and uniformly 

 increase in thickness from north to south. To the north, in the same 

 way as east of Bagh, they are frequently deficient, and never exceed 

 60 to 80 feet in thickness; to the south they frequently attain 500 feet 

 or even more. The thickness of the upper fossiliferous and calcareous 

 band increases to the south, as well as that of the underlying unfossili- 

 ferous sandstone. The coralline limestone is wanting. 



West of the Baghnee river there is a considerable tract of country, 

 about 13 miles from east to west and 15

sandstone : it is one of the largest continuous areas 



occupied by the cretaceous rocks. It is occasionally cut through by 



streams, and the metamorphics are exposed beneath, as to the south of 



Kunwara, and outliers of trap are scattered over it.
