在中部建立锶同位素地层学 白垩纪（Barremian至Turonian）间隔，与 漫长的磁静区 七个连续的DSDP/ODP部分 来自主要盆地的水将被使用， 生物地层和良好的有孔虫保存。 的影响 还将研究Sr同位素的成矿作用。 结果 将有助于了解白垩纪中期的古海洋学
英文摘要
A Sr-Isotopic stratigraphy will be developed for the middle Cretaceous (Barremian to Turonian) interval that is coincident with the long magnetic quiet zone. Seven continuous DSDP/ODP sections from major basins will be used that have well worked out biostratigraphies and good foraminiferal preservation. Effects of digenesis of Sr isotopes will also be investigated. The results will help understand the mid Cretaceous paleoceanography.
