Radiolarians of the Izu-Bonin Region

Radiolarians occur at five Leg 126 sites. Well-preserved radiolarians were recovered from Miocene and Pliocene through Holocene sections. The results of this study may help to fill the informational gap on Quaternary radiolarian distribution at mid-latitudes in the western Pacific. Radiolarian preservation is discontinuous, and, although present in Oligocene sections, specimens are poorly preserved.

放射虫（Radiolarians）在第126航次的5个钻探站位均有分布。本研究在中新世、上新世至全新世的沉积地层中采集到保存完好的放射虫标本。本研究成果或可填补西太平洋中纬度海域第四纪放射虫分布研究的信息空白。放射虫的保存状态并不连续：尽管渐新世地层中存在放射虫化石，但标本保存状况较差。
