同位素示踪是研究岩浆作用过程和演化的一个重要方法。它们包括铅同位素、锶同位素、钕同位素和铀系同位素等。其中,铀系同位素独具一格,更直接地提供火山喷发前岩浆活动的信息,更适合于研究火山喷发前的岩浆活动过程和300Ka内的火山喷发事件。许多科学工作者已经利用铀系不平衡研究岩浆作用过程并发表了一些有意义的论文。多数研究对象是 Isotope tracing is an important method to study the process and evolution of magmatism. They include lead isotopes, strontium isotopes, neodymium isotopes and uranium isotopes. Among them, uranium isotopes unique, more directly to provide information on magmatism before volcanic eruption, more suitable for the study of volcanic activity before the volcanic eruption and volcano eruption within 300Ka. Many scientists have used uranium imbalances to study magmatic processes and have published some interesting papers. The majority of research subjects are
