Аннотация доклада:
Difference in apparent resistivity values determined in galvanic and inductive electrical and EM methods depends on macroanisotropy produced by horizontal layering 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 times for apparent resistivity values between galvanic and inductive methods.
