In this paper, the approximate formulas have been derived for ELF electromagnetic field in near zone from a horizontal electric dipole on the surface of sea water and one-dimensional anisotropic rock boundary. The computational scheme exploits the concept of quasi-static approach for ELF near-field approximations. Specifically, the integrands of Fourier- Bessel representations are approximated by adopting Maclaurin's Expansion where the ratio of wave numbers for rock and sea approaches zero. The approximated solution is in good agreement with the available experimental data.
