ence to show that the heavy faulting, which characterises 

 the section, occurred wholly within the period of folding or 

 not. It was quite reasonable to assume the faulting began 

 long before the completion of the thrusting, and that a 

 general accommodation between the deformation and the 

 faulting movements took place. 



In view of the above considerations the whole section 

 was re-drawn to represent, with as much accuracy as 

 possible, the state of affairs before faulting. 



V. Results Obtained from the Amended Section. 

 Prom the alternative reconstruction of the section a new 

 set of values for the vertical uplift due to folding and for 

 the depths of the deformed zones for each section-portion 

 was obtained. These values are as follows:

VI. General Discussion and Conclusion. 



We are now able to view the results as being more or 



less of a final nature, so far, at any rate, as this preliminary 



report goes. It is seen that the folding under examination 



has been produced by the active deformation of an earth
