KRAFFT: EXOTIC BLOCKS OF MALLA JOHAR. 



No. 2 to the northern scarp of Kiogarh No. i. Near the latter it is 

 particularly well pronounced (see woodcut below).

For the whole of this distance the fault follows the strike of the 

 beds exactly. This peculiar fault can only be properly understood 

 when compared with more complicated disturbances, seen in 

 the upper flysch round the base of the Kiogarh high plateau. 

 As the comparatively soft flysch deposits are overlaid by rigid 

 masses, which must have been- originally of a considerably greater 

 thickness than is now observed, it is conceivable that, when the 

 country was subject to lateral pressure, it was principally the flysch 

 that yielded, and it also appears natural that the disturbances thus 

 effected should be most pronounced in the neighbourhood of the 

 boundary towards the overlying masses. The latter appear to have 

 evaded the pressure by being pushed to some extent over the flysch. 

 We will see below that the country south of the Kiogarh plateau 

 is more intensely disturbed than the districts alluded to above, with 

 the result that there the volcanics are folded together with the flvsch.
