Activity of isotopes of U, Th and Pa versus depth in bottom sediments from Co...

A sediment core from the European Basin with alternation of biogenic calcareous oozes and terrigenous sediments is studied by several methods. Isotopic age is determined by...

本研究采用多种方法对采自欧洲盆地（European Basin）、发育生物成因钙质软泥（biogenic calcareous oozes）与陆源沉积物（terrigenous sediments）互层结构的沉积岩心（sediment core）开展研究；其同位素年代由……测定。
