TO THE EVALUATION OF SENSITIVITY OF GEOPHYSICAL FIELDS TO SMALL CHANGES TO THE PARAMETERS OF A GEOLOGICAL SECTION
The article considers a new approach to assessing the sensitivity of geophysical fields to small changes in the parameters of the geological section, based on the calculation of local and average elasticity coefficients. The application of this approach is shown by the example of the analysis of magnetotelluric fields in a model of a three-layer medium.
