Research Field

Petrology, Geochemistry and Geochronology based on comprehensive geochemical analysis including major and trace element analyses, multi-isotope analyses such as Li, B, O, Sr, Ce, Nd, Hf, Os and Pb, and chronological methods such as K-Ar, Rb-Sr, La-Ce, Sm-Nd, Re-Os, Lu-Hf, U-Pb and U-Th-Ra under ultra-clean condition.

Eizo Nakamura’s research focuses on the understanding of the origin and evolutionary processes of planetary materials through comprehensive trace element and isotopic analyses of rocks and minerals. As such study requires analytical capability beyond that of traditional geochemistry, continuous efforts were made to develop new tracer and chronological tools. Eizo Nakamura has built one of the largest all fresh-type ultraclean chemistry laboratory, a facility that is essential for high quality geochemical work but was not readily available in Japan at that time. The construction of this laboratory allowed determination of 57 element concentrations, precise isotopic signatures of 11 elements and radiometric ages from 7 isotope systems using TIMS, SIMS and ICP-MS. These techniques are now being combined with other traditional geochemical tools such as the XRF, SEM-EDX and EPMA to build a system that can provide nearly all the chemical and isotopic information necessary to pursue the cutting edge earth and planetary material sciences research.

Using this research environment, Eizo Nakamura has been actively involved in projects related to

These projects have resulted in over 100 international publications. Many of these projects include M.Sc. and Ph.D. projects proposed and supervised by Eizo Nakamura. Education of these students has resulted in 28 Ph.D. and 10 M.Sc. theses. It is also noteworthy that many of these students have acquired a faculty position or a post-doctoral fellowship at leading institutes around the world, and are actively involved in the planetary material science research.
