THE LOOP METHOD IN EXPLORING BURIED STRUCTURES 



243 



of the loop method in the systems of geological and geophysical surveys 

 of buried structures, one should deal with the geological -geophysical condi- 

 tions necessary for its use, and consider briefly tlie results of work carried 

 out with this method. 



The most favourable objects for surveying by the loop method are structures 

 made up of sufficiently homogeneous shales or banded sand -clay or clay- marl
