四国西部の四万十帯付加体堆積物に貫入する沖ノ島-柏島地域の花崗岩類について、黒雲母K-Ar年代,ジルコンFT年代,アパタイトFT年代測定を行い、その冷却史を明らかにした結果、これら花崗岩類は約14Maに貫入し14-13Ma間に100$$^{circ}$$C以下まで冷却したことが明らかになった。

K-Ar and FT analyses were carried out on biotite, zircon and apatite from the granitic rocks in Kashiwazima district, western Shikoku in order to reveal the cooling history. These ages suggest rapid cooling of the granitic rocks in the temperature range to 100$$^{circ}$$C from 300$$^{circ}$$C in 14-13Ma.
