在分析热液铀矿床成矿作用问题时,黄铁矿作为铀的主要沉淀剂占有主要地位。文章表明,岩石的有利条件不取决于岩石中黄铁矿的存在,而决定于这样一种形式铁的含量,这种形式铁在与含铀溶液作用时容易逸出,并参与氧化-还原作用。与岩石的硅酸盐和铝硅酸盐有关的二价铁多半是这种形式。 In analyzing the mineralization of hydrothermal uranium deposits, pyrite occupies a major position as the main precipitating agent for uranium. The article shows that the rock’s favorable conditions do not depend on the presence of pyrite in the rock, but on the form of iron that easily escapes when interacting with the uranium-containing solution and is involved in the oxidation-reduction . Most of the ferrous iron associated with rock silicates and aluminosilicates is this form.
