[SGC38-P05] Trace element and Pb-Nd-Sr isotopic composition of standard rock samples

*Gen Shimoda¹ (1.Geological Survey of Japan, AIST)

Keywords:standard rock samples, trace element, Pb-Nd -Sr isotopic composition

In order to understand magmatic processes in the Earth, trace element and isotopic compositions are im@portant. To confirm geochemical data analized in our laboratory, I will analize 30 trace element and Pb-Nd-Sr isotopic compositions of 30 GSJ and USGS standard rock samples. In this paper, I will present detailed analytical proceadure in the laboratory and discuss accurasy of the determined data.
