Abstract

The first occurrence of axinite-(Mg) in Japan has been recognized at Kashio-river bed as a small boulder. Zoning of the chemical composition corresponding to axinite-(Mg) and axinite-(Fe) is observed. The mole of axinite-(Mg) varies 58% to 23%. Boron content also varies 1. to 0.63 apfu, and the insufficient boron is filled with the increase in silicon.Excess silicon maybe replace boron in the BO4-tetrahedron.
