characterizes the Moshkarevskaia fold with a steep northern hmb and a rather 

 steep south hmb, since on the profile of the XXII closure (Shirokovskaia) 

 of the structure is characterized by small angles of dip on either limb. 

 Apparently under complex seismogeological and structural conditions of 

 this section in the absence of detailed profiles (especially longitudinal) it 

 is difficult to represent the structure of this area correctly. 



According to the data of the loop method, the main bulk of the drilling- 

 was apparently related not to the Moshkarevskaia fold, but to a wide periclinal 

 nose of the Shirokovskaia structure.

Similar pecuHar linkages of two structures were often observed mtliin 

 the limits of the south-west plain by surveys with the loop method. The 

 presence of a petroleum deposit on the Moshkarev area may be connected 

 with that type of linkage. Therefore a detailed complex geological geophysical 

 survey of the Moshkarev area can give valuable data for solving the problem 

 of finding oil in a number of other areas of the Kerch peninsula both 

 from the point of view of the method and of the practice. 



Between 1945 and 1947 the loop method was used in the Crimean 

 Steppes. As a result of these observations, it was found that the physico- 

 geological conditions of this region are vuifavourable for the loop method. 

 The considerable electrical differences of the surface deposits, their weak
