Visean limestoii© block are about 60 to W degrees to the south and 80-90 degress to the north, respectively. 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 into the two dlmenstonafl (2 D) e^irth. Then It was interpreted with respect to the 2 D modelling by using the reta ed anodel curves named as T,TT,H and HH- types (Ercan WB2 a and b) Although interpretotion of Wie uppearent resistivity curves for the ID assusripttoii were given in this report they were not taken into account m making conclusive desicSon on the local geology and on the estimated geoelectrlcal section.
