8 \VTNNE: TRANS-INDUS EXTENSION OF THE PUNJAB SALT RANGE, 



But at page 506 the reference to the newer part of the series is somewhat 

 different from that observed. Over most of the district as well as in 

 the Chichali hills, I have been unable to discover any break amount- 

 ing- to definite unconformity above the nummulitic limestone, nor any 

 denudation of its surface during tertiary times ; parallel conformity, 

 with indications here and there of a break in some adjacent area, on the 

 contrary, seems to prevail, and this break may have existed even before 

 the nummulitic period. 



Some of these and other points regarding references in the Manual 

 to the geology of this district will be found mentioned where necessary 

 in the present paper. 



In a short appendix to my Salt Range Report previously mentioned, 



. , I drew up a slight sketch of the structure of the

ground beyond (west of) the Indus in the vicinity 

 of the Salt Range ; partly from what I had learned from Dr. Waagen of 

 his investigations in that ground when I was not with him, partly from 

 observations made while we were in company. The sketch, however, is 

 imperfect, as it does not mention all the rocks since found to occur at the 

 locality, the only reference to the carboniferous group being to an isolated 

 mass of some 20 feet thick of this limestone which projects from the 

 fault running up' the middle of the Lun nala, while a considerable portion 

 of the group also occurs in the hills near Kalabagh. A mass of nummu- 

 litic limestone likewise occurs in the Lun nala, faulted into its present 

 position. 



Other formations or groups are referred to in this appendix, and the 

 section seen in Chichali pass is described. In the latter a set of sandstone 

 beds, apparently intermediate between Jurassic and eocene, have been 

 grouped as cretaceous. 1 It would have been better to have qualified this 

 grouping with the statement that most of the zone so separated is un- 

 fossiliferous. The only cretaceous fossil as yet identified is that already 

 referred to as occurring in the top of the same layer which contains Jurassic 



1 At the suggestion of Dr. Waagen.
