영문 초록

The radioautographing of U-bearing cloaly slate samples were initiated in order to clarify the uranium distribution patterns in the samples of Ogcheon system. Moreover, x-ray powder diffraction and x-ray single crystal analysis studies were undertaken to identify the uranium mineral which was extracted from U-bearing coaly slate. The handspecimens were collected from the Boseong mine, located in Deokpyeong area, Goesan-gun, Chungcheongbug-do. According to the experimental studies, it has been found the following facts: (1) fixed carbon has close relation with uranium contents, (2) quartz veins developed in U-bearing coaly slate are diveded into two groups based on mode of occurrence, formation stage and uranium distribution pattern; early quartz vein (QV₁) with low uranium concentration and late quartz vein (QV₂) with high uranium concentration, (3) matrixes around QV₁ are displayed homogeneous and high uranium concentration, while matrixes around QV₂ are low uranium concentration, (4) uranium mineral is identified as a variety of autunite.
