摘要
DSDP与ODP的深入研究,发展了微量元素和稳定同位素地球化学。全球 变化、大规模构造隆起和海底扩张等在微量元素和稳定同位素演化上的反映,使微 量元素及稳定同位素地球化学成为地层划分对比的重要手段。开展以 Sr和 REE 等微量元素以及Sr、Nd稳定同位素地球化学研究,对于解决西太平洋边缘海的海 底扩张和古海洋及东亚大陆的环境变迁有重要的意义。
With the developing of DSDP/ODP, the rare elements(Sr and REE) and isotopic (Sr and Nd) geochemistry of marine sediments have been developed. The rare elements and isotopes evolutions record some important geologic events, such as past global change, large tectonic rising and sea floor spreading, and it is a useful stratigraphy tool. The studies of Sr and REE and Sr and Nd isotopes geochemistry in the western Pacific marginal sea will play an important role in the study of the sea floor spreading of western Pacific marginal sea and the evolution of the paleoceanography environments and Eastern Asia continent environments.
