Kisan-mori Mine
Kyowa-Funaoka, Daisen city, Akita pref., Japan
Synonym
Kisamori Mine
Occurrence
Moderate-T hydrothermal deposit
Moderate temperature hydrothermal deposit formed by Miocene - Pliocene (7.2 - 4.4 Ma) quartz porphyry of Nibetsu Granite intruded in altered pyroxene andesite lava and pyroclastic rocks of Oligocene - Miocene Yamayakawa Formation.
A scientific report in 1901 by Yaichiro Wakabayashi, mining engineer of this mine, suggests that the name of this mine is Kisan-mori, not Kisamori.
