Silicate Rock Analysis by Fusion Method

Geochemical data set for silicate rocks are essential for modern petrology. Concentrations of major and trace component in igneous rock sample provide many kinds of information about rock history such as eruption or solidification, magma evolution, magma genesis and source materials as well as petrographical classification. This note demonstrates advanced methods, using the ZSX PrimusII from Rigaku, to determine the chemical composition in silicate rocks by XRF.
