Helium isotope ratios and sedimentation rate models of ODP holes

A continuous age model for the brief climate excursion at the Paleocene-Eocene boundary has been constructed by assuming a constant flux of extraterrestrial 3He (3He[ET]) to the...针对古新世-始新世边界（Paleocene-Eocene boundary）处的短暂气候扰动事件，研究人员通过假定地外氦-3（extraterrestrial ³He，缩写为³He[ET]）以恒定通量输入至……，构建了一套连续年龄模型。
