内容記述 | Uranium-series dating of some hermatypic corals (Acropora sp.) reveals that the uppermost part of the Pleistocene series occurred on Tokuno-shima (Central Ryukyus) is likely to be Middle Pleistocene in age, at least older than 300, 000 years. Although the coral ages obtained are almost near or beyond the limitation of the 230Th/234U method of dating, the upper limit of the age is estimated from the mean 234U/238U activity ratio to be approximately 700, 000 years. This result is suggestive that reefy sediments formed during the last interglacial stage, 120, 000 eyars ago when sea level stood about 6m higher than the present, is exposed nowhere on the island. In addition, the absence of the Holocene Raised Coral Reef Limestone (Hanzawa, 1935) on the island may also imply that the vicinity of Tokuno-shima has been locally subsided since the last 120, 000 years. 南西諸島徳之島に分布する更新統最上部とされている亀津層(中川, 1967)から採集したサンゴ(Acropora sp.)化石について, 230Th年代を求めた。その結果, 230Th/234U放射年代測定法の適用限界か, あるいはそれを越える値(30万年以上)が得られた。また234U/238U放射能比に基づく234U年代は387, 000~709, 000年と推定された。すなわち, 亀津層の年代値は30万年以上, そしてその上限は約70万年と結論される。結局, 徳之島には喜界島などで見られる最終間氷期およびその後の数回の亜間氷期に形成された礁性堆積物(Konishi et al., 1974)や完新世の"隆起サンゴ礁石灰岩"(Hanzawa, 1935, のRaised Coral Reef Limestone)が現在陸上に露出していなく, このことは, 少なくとも過去12万年間は, 徳之島付近が沈降傾向にあることを示唆している。 | |||||
