RELATIONS OF BATITOLTTHIC AREAS 



339 



The batholxths and the Kruger schist extend far to the north and to the 

 south of the belt, so that the total area of each is much greater than is 

 shown in the table. The figures given for all the other bodies represent 

 nearly their respective total areas. Less than 7 per cent of the belt is 

 underlaid by rocks not clearly plutonic in origin, and of that 7 per cent 

 perhaps half is greenstone or other igneous rock. The 3 or 4 per cent of 

 non-igneous rock is chiefly concentrated in the tongues of Kruger schist.

The tongues have been completely cut asunder by the plutonics ; it is now 

 possible to walk from one end of the belt to the other, the whole distance 

 of 60 miles, and not once set foot on bed-rock which is other than of deep 

 seated, igneous origin (see figures 2 and 3).
