| 抄録: | An attempt to get the fission-track ages of the metallogenetic epoch of ore deposits in Kamaishi Mine was made through the dating of zircon crystals extracted from both Ganidake and Kurihashi granodiorites, which are intruded in the Kamaishi mining area and both intrusion bodies appear to be genetically related to the mineralization of the ore deposits of this mine. The dating results yield the age of 111±7 my for the Ganidake granodiorite and 95±9 my for the Kurihashi granodiorite. Consequently, the fission-track ages of the metallogenetic epoch of the ore deposits in Kamaishi Mine should also range from 111±7 my to 95±9 my. |
