The chemical similarity of the magnetite-bearing amphiboltes of the Yangyang iron mine to mixtures of sedimentary pelites and limestone or dolomite and to the Gyeonggi para-amphibolites (So, 1974) is consistently indicated by all the chemical data of the rocks. Eight amphibolite samples were each analyzed for 18 elements, by wet chemical and emission spectroscopic methods, and these chemical data were compared with the para-amphibolites from the Gyeonggi metamorphic complex. Petrography and oxidation ratios were also considered.
