研究元素在岩石和矿物中的存在形式和分布规律是地球化学的迫切问题之一。确定放射性元素低浓度的数值及其技术可能性具有重要意义。近年来发表了一系列主要是研究花岗岩类成分的岩石中放射性元素分布的作品。变质岩则注意的很少。查明铀的总浓度及其难溶和易溶形式的分布特征是研究放射性元素的主要方法之一。通常通 The existence and distribution of research elements in rocks and minerals are one of the most pressing problems in geochemistry. It is important to determine the low concentration of radioactive elements and their technical possibilities. In recent years, a series of works have been published that primarily focus on the distribution of radioactive elements in rocks of granitic components. Metamorphic rocks are very little attention. Identifying the total concentration of uranium and the distribution of its insoluble and soluble forms is one of the main methods of studying radioactive elements. Usually pass
