Tertiary Eocene Rocks, Brown Calcareous Sandstone, Nummulite, 

 Limestone, Marls and Alum Shales with Lignite, 



A band of claystone, in some places highly ferruginous and in 

 others nearly as white as pipe clay, seems to mark the base of this 

 formation. It has exactly the appearance of the ferruginous clay- 

 stones described as occurring in the Oolite shales, and as it may be 

 seen occasionally passing into black bituminous shales which are in 

 rapid process of decomposition, its origin is doubtless identical. 



Resting on this is an incoherent greenish brown calcareous sand- 

 stone, which east of Kuttha is devoid of organic remains. At this 

 place, however, it becomes more calcareous, contains a few nummu- 

 lites and a considerable number of gasteropodous molluscae. On 

 proceeding westward to Moosakhail, the bed becomes a coarse arena- 

 ceous limestone, and abounds in fossils similar to those which occur 

 throughout all the rocks of the nummulite limestone series, none 

 of those characteristic of the formations inferior to it having been 

 detected. 



To this sandstone there succeeds a deposit of very varying thick? 

 ness of dark bituminous alum shales containing irregular beds and
