208 WYNNE : GEOLOGY OF KUTCH. [PART II. 



The northern declivity, as Colonel Grant deseribeSj is covered by 

 impenetrable babul jungle and travergedby a deep ravine, no uncommon 

 occurrence in ground formed of trap like this, which seems to descend 

 the hill side further on the north than elsewhere.* 



To the south its base is thickly covered by calcareous, sub-recent, 

 tufaceous concrete, and about half way up the hill the fine white sand- 

 stones contain Falmozamia of the kind most frequently met with. 



Eastwards of Dhenodur, where the broken hilly ground formed of the 

 lower Jurassic or transition beds adjoins the alluvial plain extending west- 

 wards from Soomraisir, one or two small exposures of tertiary, fine- 

 grained, yellowish, shaly grits were observed to contain a few gastropods 

 and bivalve shells in bad preservation — Ostrea and Pecten. 



The ground being low, the relations of the two formations are 

 obscure, but it is probable that the junction is efiected by means of a 

 fault. 



* The upper part of this ravine being somewhat more open is perhaps the crater 

 alluded to by Colonel Grant in his paper on Kutch. The breccia he speaks of is 

 probably the subrecent concrete.
