Abstract
In order to investigate geophysical structure, especially conductivity structure, of the crust and the mantle in the northeastern Japan, exploration was carried out by MT and GEMIT method. The GEMIT is an electromagnetic prospecting method recently developed, which means geo-electromagnetic induction tomography. This report concerns the first traverse carried out on the above-mentioned area in 1990. Thirty six observation points were located at latitude 40[degree]35 to 45'N from the sea of Japan to the Pacific Ocean. Three components of geomagnetic field and two horizontal components of electric field were measured at each point. Geomagnetic and differential electric fields detected by a system of three induction magnetometers and two sets of differential electrodes were recorded by 14-bit digital recorder. Planar and sectional distribution of resistivity in the crust and the mantle was profiled been on these data. In this paper, these profiles are shown and structure of the upper and lower crust and the mantle is discussed. 6 refs., 5 figs.
