Structural Features near the Yaguki Mine, Fukushima Prefecture

Abstract

Geological mapping of the area near the Yaguki mine indicates that the Paleozoic formation has a synclinal structure with its axis plunging N 14°-19°W 22°. Intrusion of granitic rocks formed some local domes. The ore bodies are localized on the trough of the syncline and the top of the domal structures. This criteria would be very valuable in prospecting for mineral deposits in this area by delineating the local dome-structures.
