Abstract Because of the great potential for zircon to provide insights into crustal melting and evolution, much work has been done to develop tools to interpret its trace element concentrations. There are several complexities to zircon/melt partitioning that appear to be underappreciated, and these are illustrated using a combination of new and existing data. First, sector zoning causes significant dispersion in the population of zircon compositions even for those grown from a homogeneous melt. Second, many analyses of natural crystals contain trace elements at unrealistic concentrations: there are multiple potential sources for this apparent contamination. Third, new experimental data show that Henry's Law is obeyed by rare earth elements in zircon, despite recent suggestions to the contrary. Fourth, zircon/melt partition coefficients are functions of temperature, melt composition and in some cases oxygen fugacity, rather than being constants.

解释锆石中稀土元素浓度的关键概念

摘要 由于锆石在提供地壳熔化和演化方面的巨大潜力，人们已经做了很多工作来开发解释其微量元素浓度的工具。锆石/熔体划分有几个复杂性似乎没有得到充分重视，我们结合新数据和现有数据来说明这些问题。首先，扇形分区会导致锆石成分的显着分散，即使是从均匀熔体中生长的锆石成分也是如此。其次，对天然晶体的许多分析都含有浓度不切实际的微量元素：这种明显的污染有多种潜在来源。第三，新的实验数据表明锆石中的稀土元素遵守亨利定律，尽管最近有相反的建议。第四，
