DESCRIPTIVE GEOLOGY: NUMMULITIC ZONE. 205 



important changes in this southern band of the Jurassics have 



been effected. 



Returning once more to the main line of .horizontal section 



. , XT No. ^, we find the great Nummulitic form- 



Section from Nugree •" & 



to near Dhar. ation extending the rest of the way from 



Nugree to Dhar, and only broken by two thin bands of the Kuldana 

 beds. The main line of section crosses the south-west spur of 

 Bhumkot, 7,028 feet, at Liran, but behind it I have introduced the 

 more comprehensive section as it crosses Bhumkot itself. Viewed 

 from near Loruh with the early morning light playing on Bhumkot's 

 rugged and bare slopes, the anatomy of the hill comes out very dis- 

 tinctly. The details in the horizontal section are introduced from 

 a drawing made under those circumstances which, considering the 

 distance of the point of view, may be taken as practically free from 

 errors of perspective. 



A peculiar feature in the section is the two more or less broken 

 bands of Kuldana rocks which run like red streaks over hill and 

 hollow. In some cases the amount of gypsum associated with them 

 is considerable. On the " S." of Seer in the Nugree valley the 

 gypsum is about 100 feet thick, the apparent dip of the bands being 

 6o° N.W. The section was — 



(1) Nummulitic limestone. 



(2) Banded grey and white gypsum .... 40 feet. 



(3) Gypsum and little red clay | 20 ,, 



(4) Repetition of (2) and (1), 



In other localities, as south-west of Loruh, purplish and green 

 shales with banded white and grey gypsum and calcite veins, and 

 sometimes with hard compact quartzose beds, make up the band. 

 About the u D " of Dheree Keyaluh in the stream-bed close* to the 

 gypsum of the above band, a spring issues from the Nummulitic 

 limestone giving off sulphuretted hydrogen and depositing sulphur 

 among the weeds in the stream-bed. The limestone in the vicinity, 

 and also the bands of gypsum and clay, are much twisted. 

 Lenticular patches of limestone are sometimes veined with gypsum.
