随着人们对物质世界认识的不断深化,地球化学研究的领域已不仅是元素在空间和时间上的分配和迁移问题,而且扩展到自然界不同元素同位素的分配和迁移问题。应该说,稳定同位素地球化学是这一学科更深一个层次的发展,因此有着广阔和潜在的发展前景。本文主要谈:目前国际上关于轻元素稳定同位素地球化学研究的一些情况。一、基本理论研究自然界稳定同位素的分馏机理从物理化学的角度来看,可分成两大类:一类是平衡
With the deepening of people’s understanding of the physical world, the field of geochemical research has not only been the issue of the distribution and migration of elements in space and time, but also the distribution and migration of isotopes of different elements in nature. It should be said that stable isotope geochemistry is a further development of this discipline and therefore has broad and potential development prospects. This article mainly talks about: At present, some international studies on stable isotope geochemistry of light elements. First, the basic theory of natural stable isotope fractionation mechanism from the physical and chemical point of view, can be divided into two categories: one is the balance
