Abstract
Fe compounds of volcanic basalt samples distributed at the Hantan riverside in Cheorwon were investigated by means of X-ray diffractometry (XRD), X-ray fluorescence spectroscopy (XRF) and $M{\ddot{o}}ssbauer$ spectroscopy. We found that samples were typical basic rock which consisted of augite, anorthite, albite and sanidine etc. They had the total amount of iron compounds including hematite (${\alpha}-Fe_2O_3$) varies from 6.20 w% to 12.8 w% depending on the different regions by XRF. The $M{\ddot{o}}ssbauer$ spectra of the samples were consisted of three doublets. The balance state of Fe ions of all samples were chiefly $Fe^{2+}$, and $Fe^{2+}/Fe^{3+}$ ratios were 2.27~3.42.
