Uranium Distribution Patterns and U-mineral in the U-bearing Coaly Slate of Ogcheon System
옥천계(沃川系) 함(含)우라늄 탄질암중(炭質岩中)의 우라늄의 존재상태(存在狀態)와 광물종(鑛物種)
Abstract
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 (
