近十年来,在苏联和国外的铀矿普查中发现了许多巨大的矿床,它们皆存在于沉积岩中。现在沉积岩乃是开采铀的主要源泉;到1960年为止,沉积岩中铀储量占已查明的全部铀储量的70%还多。所以研究沉积岩中铀富集形成条件的重要性就非常明显了。许多铀矿发现于古生代之后的陆台盖层建造中, In the last ten years, many huge deposits have been discovered in uranium censuses in the Soviet Union and abroad, all of which are found in sedimentary rocks. Sedimentary rocks are now the main source of uranium mining; by 1960, more than 70% of the total uranium reserves were identified in sedimentary rocks. Therefore, it is very important to study the formation conditions of uranium enrichment in sedimentary rocks. Many uranium deposits were found in the continental shelf after the Paleozoic,
