Development of an orbitally tuned Late Miocene time scale (5-12 Ma)

天文调谐技术是目前最准确的绝对测年方法的沉积物记录跨越时间间隔的最后35马天文学家提供了一个有效的和精确的轨道解决方案的变化在地球的轨道参数.轨道调谐的地质时间尺度已经成为更新世和上新世的标准年表。我们的目标是在南太平洋1237站（第202航段）扩展和天文校准“磁极性时标”、氧同位素地层学和生物地层学至12 Ma。到目前为止，这是唯一的海洋网站，满足几乎所有的标准，提供一个完整的新近纪参考部分整合到一个轨道调谐氧同位素地层磁性地层学的优秀框架。这一建议被嵌入到与DFG项目Ku 649/18和Ti 240/13的联合努力中，以开发整个新近纪的“磁极性时标”和氧同位素地层学。

The astronomical tuning technique is at present the most accurate absolute dating method for sediment records spanning the time interval of the last 35 Ma for which astronomers provide a valid and precise orbital solution for variations in Earth's orbital parameters... The orbitally tuned geological time scale already became the standard chronology for the Pleistocene and Pliocene... Our goal is to expand and to astronomically calibrate the 'Magnetic Polarity Time Scale', the oxygen isotope stratigraphy and biostratigraphy to 12 Ma at South Pacific Site 1237 (Leg 202). So far, this is the only marine site that meets nearly all critera of providing a complete Neogene reference section by integrating the excellent framework of both magnetostratigraphy into an orbitally tuned oxygen isotope stratigraphy. This proposal is embedded into a joint effort with DFG project Ku 649/18 and Ti 240/13 to develop a 'Magnetic Polarity Time Scale' and oxygen isotope stratigraphy for the entire Neogene.
