DESCRIPTIVE GEOLOGY: UPPER TERTIARY ZONE.

Section near Murree. 



The section near Murree has been very well described by Wynne, 



and for details I refer the reader to his paper. 1 



The diagrammatic sketch-section given below 



gives the result of my own traverse across the section from Murree to 



Derriya Gulee.

a= Nummulitic limestone. 



The important point about the above section is that it shews a 

 definite passage from the Kuldana beds up into the Murree beds near 

 the 3^ milestone from Murree, the passage being of the nature of a 

 gradual interbedding of the one set of rocks with the other, which is 

 the most perfect and reliable form that a passage-bed can take. 

 Hence I have represented on the map and in the section a normal 

 junction here between the two sets of beds. By itself perhaps such 

 a section would not be conclusive, especially since the exposures 

 follow a rather narrow and disintegrating ridge, and the dips are 

 high, but it will be remembered that in the gently folded rocks 

 of Laichi Khun 2 this same zone of Murree beds follows in a per- 

 fectly normal and natural order above passage-beds resembling 

 these Kuldana beds, whilst they in turn lie normally and natur- 

 ally upon the Nummulitic limestone. Wynne from his remarks, page 

 69 of his last-quoted paper, was evidently of the same opinion. It 

 will be noticed that north of the Kuldana cross-roads the dip of the 

 beds is south-east and somewhat irregular, so that the general law 

 that these younger Tertiaries dip towards the next zone to the north- 

 west is here departed from.
