Abstract Though the utility of calcium isotopes is broad, examples of applications are still relatively sparse. Some of this paucity, as with many metal isotope systems, may derive from a perception that the analytical tool is difficult to access. Alternatively, potential users may be deterred by a sense that calcium isotopes are ambiguous, difficult to interpret, and/or complicated by too many interrelated processes. Here we provide an overview of the quantitative modeling approaches available to facilitate interpretation of calcium isotopes in Earth systems, in particular their ability to push interpretations beyond the qualitative. While no method is perfect, the variety of approaches described here offer an accessible toolset that is incredibly valuable. We suggest that the calcium isotope community should be expanding the use of such techniques, noting their limitations and striving to improve upon current methods over time.

定量建模对 Ca 同位素解释的效用

摘要 尽管钙同位素的应用范围很广，但应用实例仍然相对较少。与许多金属同位素系统一样，这种缺乏的部分原因可能是由于认为分析工具难以获得。或者，潜在用户可能会因为钙同位素含糊不清、难以解释和/或因过多相关过程而变得复杂的感觉而望而却步。在这里，我们概述了可用于促进地球系统中钙同位素解释的定量建模方法，特别是它们将解释推向定性之外的能力。虽然没有一种方法是完美的，但这里描述的各种方法提供了一个非常有价值的可访问工具集。
