加拿大地质调查局应用花岗岩中放射性元素分布和所产生热的数据、区域放射性测量、重力和磁法的资料对铀的区域分布规律进行了研究。已经得到一些初步的规律性。例如,区域重力负异常带往往与高铀含量花岗岩类的分布相一致。铀矿化与花岗岩的关系密切。当有利的构造与水文地质条件相结合时,高铀含量的花岗岩所放出的热对低温的矿化过程来说是不可忽视的。阿萨巴斯卡盆地高品位铀矿床的形
The Geological Survey of Canada conducted a study on the regional distribution of uranium by using the radioactive elemental distribution in the granite and the data on the generated heat, regional radioactivity measurements, gravimetric and magnetic data. Have got some preliminary regularity. For example, regional negative gravity anomalies tend to be consistent with the distribution of high-uranium granitoids. Uranium mineralization and granite are closely related. When favorable structures are combined with hydrogeological conditions, the heat released by high-uranium granites can not be ignored for low-temperature mineralization.
