美国铀矿地质工作者从1970年开始,对美国砂岩型铀矿床及其主岩中的铁-钛氧化物进行了研究。第一批研究成果发表在1974年由国际原子能机构在雅典召开的铀矿地质讨论会论文集中。到八十年代,研究工作进入了一个新阶段,这是当前美国砂岩型铀矿床的重大研究成果之一。美国地质工作者认为:“碎屑状铁-钛氧化物是与铀矿定位有关的地球化学环 US uranium geologists have been studying the iron-titanium oxides in sandstone-type uranium deposits and their host rocks in the United States since 1970. The first research results were published in the Proceedings of the Uranium Geology Symposium held by the International Atomic Energy Agency in Athens in 1974. By the 1980s, the research work has entered a new phase, which is one of the major achievements of the current sandstone-type uranium deposit in the United States. US geologists think: "Fragmental iron - titanium oxide is the geochemical ring associated with uranium ore localization
