The Fuke Gold Mine is situated in the northern part of Yamanomachi in the northern part of Kagoshima Prefecture.
There are more than ten gold-bearing quartz veins in propylite, and these veins can be divided into the following two types ;
a) Hompi-type; represented by Hompi (main vein in the Fuke Mine) typically, strikes N 60°-80°E, dips 70°-80° NW. Dark green chlorite is found as one of gangue minerals in the upper part of each bonanza in addition to quartz and calcite.
b) No. 1 Vein-type ; represented by No. 1 Vein typically, strikes N 30°-40°W, dips 70°-80°W, bears quartz and calcite.
Besides the ore veins, there are fissures containing water. These cross the Hompi-type veins, striking N 15°E and dipping nearly vertical.
Compared with geotectonic lines of Kyushu, the strikes of Hompi-type are nearly parallel to the Usuki-Yatsushiro tectonic line. The strikes of No. 1 Vein-type are parallel to the long axis of Ariake Bay or to the tangent of the western edges of Kyushu Island. The strikes of the water veins are parallel to the Hinagu fault line or to the Hamamachi-Hitoyoshi line.
It is considered that three geotectonic lines in Kyushu intersect in the Fuke district. The ore veins are the older and the water veins are the younger.
