Abstract
Difference in apparent resistivity values determined in galvanic and inductive electrical and electromagnetic methods depends on macroanisotropy of layered cross-section and decreased penetration depth of galvanic methods without changing penetration depth of inductive methods. Joint influence of these two factors in case of high contrast of layers' resistivities results in difference in several tens of apparent resistivity values.
