英文摘要
We developed a new analytical method for rapid determination of Re and Os isotopes using a MC-ICP-MS (NEPTUNE) and sparging method. As a result, sample throughput of Re-Os analyses became several times higher than that of the N-TIMS method. We applied this method to pelagic chert samples from the Inuyama Area, Mino Belt, and have succeeded to reconstruct the secular variations of marine Os isotope ratio through the Triassic period.
