説明

The results from recent east-west gravity and magnetotelluric traverse across the Fuji River, Central Japan, show that (i) extremely low Bouguer anomalies are distributed along the Fuji River and characterized with a strong horizontal gradient 4.5 mgal/km, and (ii) a low-resistivity zone appears along the Fuji River.<BR>The profile of density distribution was computed. From the results, it is seen that the sedimentary basin in this section has a steep slope beginning from the eastern part of the surveyed area and continuing even under the Itoigawa-Shizuoka Tectonic Line. The high-conductivity and low-density zone, whose density is smaller than 2.3 g/cm3, has a width of 1.5-2.0 km. These zones are possibly caused by the fracturing of rocks due to fault activity.
