2017年中国科学院海洋研究所“大洋岩石圈与地幔动力学实验室”建成。未来5年,该实验室在国家自然科学基金重点项目(编号:41630968)的资助下,用珍贵的太平洋、大西洋和印度洋洋中脊玄武岩(MORB)、辉长岩和深海橄榄岩(MORP)研究地球化学和地幔动力学的几个基本科学问题:1用Ti-Zr-Hf稳定同位素验证“Nb-Ta和Zr-Hf元素对质量分异的假说”;2从MORB演化过程和地幔熔融过程检验目前对铁同位素分馏的基本假说,即重Fe同位素与Fe3+有亲和性,且比轻Fe同位素和Fe2+更不相容;3提出并试图检验地幔高氧逸度是板块构造的结果,即含有大量Fe3+的蛇纹石化大洋岩石圈地幔橄榄岩俯冲到深部地幔所致;4对代表性的MORB样品和中国东部新生代碱性玄武岩样品进行铀同位素研究,检验Andersen等(2015)有关地球演化过程中壳幔循环导致的内、外动力地质过程的相互关系。
2017 Institute of Oceanology, Chinese Academy of Sciences “Oceanic lithosphere and mantle dynamics laboratory ” built. Over the next five years, the laboratory will be supported by the National Natural Science Foundation of China (Grant No. 41630968) with research on precious Pacific, Atlantic and Indian Ocean Ridge Basalts (MORB), gabbro and peridotites (MORP) Geochemistry and mantle dynamics: 1 Validation of stable isotopes with Ti-Zr-Hf “Hypothesis of mass fractionation of Nb-Ta and Zr-Hf elements”; 2 From the MORB evolution and mantle melting The process tests the current underlying hypothesis of iron isotope fractionation that heavy Fe isotopes have affinity with Fe3 + and are more incompatible than light Fe isotopes and Fe2 +; 3 proposed and tried to test the mantle high oxygen fugacity as a result of plate tectonics, That is, serpentine oceanic lithospheric mantle peridotite containing large amounts of Fe3 + due to subduction into the deep mantle; 4 uranium isotope studies of representative MORB samples and Cenozoic basaltic basalts in eastern China to test the Andersen et al. (2015) Correlation between inner and outer dynamic geologic processes due to crust-mantle circulation during evolution.
