Apatite and Trace Elements in the Skaergaard Intrusion

这项工作的目的是了解高温 据推断，这些过程影响了矿物学和体积 Skaergaard侵入体形成的堆积岩成分 凝固了 特别是它将集中在条件导致脚趾 磷酸盐矿物磷灰石的形成--也就是说， 由截留的间隙硅酸盐液体结晶形成，或 它的形成是由于磷和卤素（u，f）的引入。 从周围的岩石中分离出来 这项研究的结果应该 为镁铁质侵入体的演化提供了关键的限制 在组成上。

The proposed work is aimed at understanding high temperature processes that are inferred to have affected the mineralogical and bulk compositions of cumulate rocks formed as the Skaergaard intrusion solidified. In particular it will focus on the conditions leading toe formation of the phosphate mineral apatite -- i.e. did this mineral form by crystallization of trapped interstitial silicate liquids or was it formed in response to introduction of phosphorus and halogens (u, f) from the surrounding wall rocks. The results of this study should provide critical constraints on how mafic intrusions evolve compositionally.
