Abstract

It has been found that primitive basaltic magma evolves by crystallization differentiation in the repeatedly refilled magma chamber to magma of chemical composition of the upper continental crust, and that arc volcanic rocks are lavas extruded from the chamber in the act of undergoing this transformation. To confirm these observations further, it is necessary to examine major element and other minor element compositions of arc volcanic rocks. First minor element compositions and then major element compositions are presented.
