168 SUB-HIMALAYAN ROCKS OF N. W. INDIA. [CHAP. VI. 



of the features appearing as patches on the map are but the termination 

 of those which we know to be more or less continuously represented for 

 several hundred miles to the eastward. In this respect the position is 

 The re-ion of our map favourable ; we can here add the coincidence of the 

 SS^£J5-E£ simultaneous partial extinction of the several 

 Z th l^ tmh ZZJn Matures to the coincidence of their continuity 

 mass - elsewhere. The agreement seems wonderfully 



complete. In the Dhaoladhar at Dalhousie we seem to have the termi- 

 nation of the great line of the Eastern Himalaya, at least in its character 

 of an axis of crystalline intrusive rocks. The minor characters \re in 

 keeping with this supposition : what we have seen to the eastward 

 described as a broad band of thorough granite, distinctly intruded, is 

 here represented by granitoid gneiss showing quasi-intrusive characters. 

 At what we might consider a due distance from the end of the main line 

 of elevation the whole area of the Lower Himalaya disappears, and the 

 stratigraphical conditions show that this is connected with the structure : 

 the strike of the rocks bends round with the boundary, the cross-section of 

 which throughout the bend is quite the same as elsewhere. Throughout 

 all these changes each zone of rocks is represented. The peculiarities 

 we have noticed on the Chor correspond with those of the Dhaoladhar ; 

 it is a gneissose, quasi-intrusive mass, and may here represent the more 

 truly granitic rock of the middle zone in the sections further to the east. 

 Even in the Sub-Himalayan series the same facts are observed ; the 

 Subathu group becomes covered up west of the Sutlej, the middle 

 group disappears in the same manner, and we have seen that the 

 successive ridges of the upper group are cut off en echelon in the 

 region of the Beas. It will be remembered that in Chap. III. (p. 19) 

 it was stated that in Huzara, west of the Jhelum, a different system 

 of disturbance prevails, running nearly at right angles to that of the 

 Himalaya, and deeply inserted into the prolongation of* the Himalayan 

 area west of Kashmir.
