众所周知,产铀矿岩体往往具有含铀量高,铀容易浸出的特点。五十年代法国鲁博和科庞就注意到产铀矿岩体新鲜岩石中含有放射性强度很高的细小黑色矿物。后来到60年代用电子探针确定它为品质铀矿。随着我国铀矿地质研究工作的进展,1974年黄志章等在DK岩体光薄片中、1975年我们在C岩体的光薄片和人工重砂中, It is well known that uranium ore-bearing rock masses often have the characteristics of high uranium content and easy uranium leaching. In the fifties, French Rupert and Coperbon noticed that the fresh rock of uranium ore bodies contained fine radioactive black minerals. Later, by the 1960s, electron microprobe was used to determine it as a quality uranium deposit. With the progress of uranium geology research in China, Huang Zhizhang etc. in DK rock photolithography in 1974, we are in the C rock mass of light sheet and artificial heavy sand,
