本文对当前在新生代古海洋Nd同位素演化及其古环境意义研究方面的最新成果进行了简明的阐述，说明在巴拿马海峡于5－3Ma关闭前后，太平洋和大西洋洋流的变化与其海水Nd同位素的变化相对应。但同期的印度洋Nd同位素没有明显变化，其原因需要进一步研究。
Recent achievements in obtaining information of the evolution of oceanic Nd isotopic composition in the Cenozoic and its environmental significance are summarized. Variations in the circulation between the Pacific and Atlantic and in Nd isotopic composition corresponded to the closing of the Panama seaway 5 - 3 Ma ago. However, the cause for the little variation in Nd isotopic compositon in the Indian Ocean in the same period is not clear and needs further work to reveal.
