众所周知,相对于不产铀岩体来说,产铀岩体往往具有含铀量高,铀容易浸出的特点。50年代法国鲁博和科庞就注意到产铀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晶质铀矿。随着我国铀矿地质研究工作的进展,74年黄志章等在DK岩体光薄片中、75年欧振武和我们在C岩体的光薄片和人工重砂中,用乳胶照相、微比重、微化分析、x—光粉晶分析和电子探针方法确定了晶质铀矿。在M岩体工作的野外队同志也在那里发现有晶质铀矿。后来,在江西的H、E、I和J,广东的G、B,湖南的
As we all know, relative to uranium-free rock mass, uranium rock mass often contains high uranium content, uranium is easy to leach characteristics. In the 1950s, Rouss and Coper of France noticed that the fresh rock of the uranium pluton contained fine radioactive black minerals. Later, by the 1960s, electron microprobe was used to determine it as a crystalline uranium deposit. With the progress of uranium geology research in China, Huang Zhizhang et al. Used the photographs of latex, microgravimetric and microdissection in the photographs of DK porphyry in 75 years of Ou Zhenwu and our light sheet and artificial sand in C rock mass. Analysis, x-ray crystallographic analysis and electron probe method to determine the crystalline uranium. Field team comrades working on the M rock also found crystalline uranium there. Later, in Jiangxi H, E, I and J, Guangdong G, B, Hunan
