ABSTRACT

The elemental composition data for seventeen GSJ rock reference samples, “Igneous rock series”, are compiled and presented as the 1988 concensus values for major, minor and trace elements. This compilation is based on previously published 1986 values and new 160 analytical reports we received during the years of 1987 and 1988. In the 1988 values, the 1986 values of poor reliability have been widely revised and many of data lacking in the former compilation are newly added.
