Uranium Distribution in Uranium Ores and Source Rocks. Final Report for the Period 1 October 1976-30 September 1981

摘要

A variety of uranium ore samples from different localities was processed in the usual way: samples were cut and autoradiographed. On the basis of these pictures areas were selected for thin sections. These polished thin sections were investigated microscopically in transmitted and reflected light and the most typical or most important areas were photographically documented. Selected portions have then been routinely analyzed using an ARL-SEMQ electron microprobe under standard conditions (15kV acceleration, 15nA sample current). Most of the analyzed areas have also been documented by secondary electron scanning images and X-ray scans for the most important elements present. (Atomindex citation 13:668327)
