| 摘 要： | 传统的对控矿层间氧化带的研究往往偏重于铀及其相应的伴生元素(Se、Mo、V、Re、Ga等)的地球化学行为，而对常量元素中非变价元素如：Si、Al、Na、K等研究还很不充分。事实上，层间氧化作用过程中，随着成矿流体的运移和水一岩反应的进行，介质的物理化学条件如Eh、pH等必然会发生显著的改变，而这些改变或多或少的总会在成矿主岩中最常见的元素如：Si、Al、Fe、Na、K的地球化学行为上显示出来。这种改变首先体现在含有上述元素的矿物上的一系列变化，并最终导致元素含量上的改变。不同的元素在这一过程中具有不同的地球化学行为，按照其迁入迁出的强度，这些元素可以划分为活动组分、次活动组分和惰性组分3类。

| Abstract: | The study on interstratified oxidized zone is usually focused on the behaviors of uranium and related elements, such as Se, Mo, V, Re and Ga, while the major elements including Si, Al, Na, K is not sufficient. In fact, the physical and chemical conditions such as Eh, pH, temperature and pressure will be changed obviously with the migration of ore-bearing fluid and reactions between water and rocks during the interlayer oxidation. And, therefore, the behavior of major element such as Si, Al, Fe, Na and K will response to such change. The first varies appears in the form of the minerals which contains such elements, and result in the content of above element. These major elements can be divided into 3 parts as activity, sub-activity and non-activity based on the density of migration in and out. |
