must fall on the boundary between Nummulitic limestone and 
Murree sandstone. 
In the eastern part of the Salt Range I had the opportunity in 
several places, of studying specially the beds between the Nummulitic 
limestones below and the overlying sandstone formation. Near the 
hamlet of Mola, not far from Phadial, I observed the following 
section (Fig. 11).

The same beds are somewhat better developed in a brook north 
of the hamlet Lheri Saidan (Fig. 12) (vde topographical map, 
1 inch =1 mile, No. 43 H, District Jhelum). They probably 
represent the Upper Nummulitic. The strata dip to the north-west 
at about 20°. The nodular marls have exactly the same character 
as the corresponding bitumen-bearing beds of the region of Golra, 
Ratta Hotar, and Murree (Kuldana). They do not, however, bear 
bitumen here. In this as well as in the small thickness of the clayey 
formation between the Nummulitic limestone and the sandstones, 
the facies differs from that of the western Salt Range. Gypsum and 
cellular limestones are also absent.

Near Phadial, at the base of the sandstones, however, I have 
found the same giant oolite which, near Jaba in the western Salt 
Range, forms the rock overlying the oil-bearing beds. We find 
the giant oolites also in the middle Salt Range overlying the 
Nummulitic limestone. On the plateau south of Kallar Kahar 
(special map No. 43 D 9, Attock and Jhelum District) they are well 
exposed (wde Fig. 13). The giant oolite therefore marks a very
