钠交代型铀矿是指以发育广泛而强烈的、在成因上与铀成矿紧密联系的前提蚀变——钠长石化(在某些情况下为霓石化和钠闪石化)为特征的那些铀矿床,其矿化作用是由各种基体在含铀的钠质溶液作用下发生的。
Sodium-associated uranium deposits are those that are characterized by extensive and intense pre-existent alteration of albite-albite (in some cases, niobium and sodium-sapphire) that are intimately associated with uranium mineralization Uranium deposits, the mineralization of which is caused by a variety of substrates in uranium containing sodium solution.
