Electrical and radiometrical prospecting surveys for uraniferous copper chlorite veins in granite were carried out at Yasaka and Dodani mines, Yamaguchi prefecture. The indications of spontaneous polarization and resistivity methods are unsuitable for these thin veins, therefore, a special current-potential method in which the one vein was taken as one electrode. was used. In the Yasaka mine high count anomalies were found in adit level by the radiometrical survey, and the current-potential method also seems to be useful for tracing the veins. In the Dodani mine radioactive anomalies were not so large as those of the Yasaka mine in adit level. The current-potential method seems to be more applicable to low radioactive anomaly veins. (auth)
