Chapter VII.— GENERAL CONSIDERATIONS. 



Detailed accuracy of map : The four disturbance zones compared : Relative 

 elevation of earth's crust in the different zones : Relative compression of 

 the earth's crust in the different zones : Relative amount of denudation of 

 the earth's crust in the zones : Two ways of accounting for the above : 

 Remarks on the boundary-faults to the S. of each zone : Cause of the 

 different degrees of upheaval compression and denudation in each zone : 

 Zonal structure beyond Hazara : Crystalline axis of the Himalaya : 

 Its mode of intrusion : Unity of penological characters : Compared with 

 gneissic rocks of S. India : Its metamorphic action on the intruded rocks : 

 Upward limit of the sedimentary rocks influenced by this metamorphism : 

 Date of the appearance of the gneissose-granite at least pre-Triassic : 

 Dynamic metamorphism of the Himalaya : Constancy over the whole 

 length of the Himalaya : Its cause : Some peculiarities in the disturb- 

 ance of the Himalaya : Mountain systems of the Hindu Kush and 

 Himalaya, their distinctness or not : Sudden change in the direction of 

 the strike at the Jhelum R. : Similar small changes in Salt Range : Final 

 remarks on the development of the Himalaya and their western con- 

 tinuation as a whole 259
