However, geophysieaHy, it to difficult to discriminate whether these sharp boundaries coincides with faulta, contacts or with discoiifonnilies. It iş clear that electrical resistivity sounding mea urementÄ necessary but not sufficient for inveotigating slopes, locations and forms of the discontinuités. Therefore, It is recommended to use electrical resistivity profiling technique in addition, in order to delini ite location öf th« horizontal discontinuiti!«# and to Gualyze the origines of the anomalous parts an the sounding curves. For the of continuity of the local geology» in perpendicular dlrectiott to fä& expaiiaion profile» üireo (lirnensional (S D) sturucture were reduced in to the two dlmenstonafl (2 D) e^irth.
