Axinite, in association with epidote, stilpnomelane and chlorite, was newly found from green-schist in the Sangun metamorphic zone. Complete chemical analysis of axinite has not been successful, because most grains of the axinite include a number of minute grains of quartz and perhaps of sphene. The axinite may be manganoan one, and has optical properties such as followings: α = 1.674, β=1.680, γ=1.683, optically negative, 2V=70°. The X-ray diffraction patterns show noted similarity to the patterns recorded for axinite from Dauphine, France. The refractive indices for the axinite are unexpectedly lower than those for the manganoan axinite so far reported by many authors.
The axinite was recognized as one of metamorphic minerals which were stably crystallized under the condition of the quartz-albite-muscovite-chlorite subfacies of TURNER and VERHOOGEN (1960).
