Halogen Distribution in the Great Dyke, Zimbabwe

卤素在大型层状侵入体中的分布是有意义的，因为卤素的变化提供了关于这些侵入体的脱气历史的信息。卤素分布也为理解富含挥发分的流体在诸如铂族元素等经济上重要的痕量金属的运输中可能发挥的作用提供了证据。该项目旨在研究含水相中的卤素，以了解富含挥发分的流体在诸如铂族元素等具有重要经济意义的痕量金属的运输中的作用。含水矿物将用电子探针进行分析，全岩分析将用电感耦合等离子体进行。这项研究的结果应该适用于其他层状侵入体，如Stillwater和Bushveld。

The distribution of halogens in large layered intrusions is of interest because halogen variations provide information on the degassing history of these intrusions. Halogen distributions also provide evidence for understanding any possible role by volatile-rich fluids in the transport of economically important trace metals such as the platinum group elements. This project is to look at halogens in hydrous phases to understand the role of volatile-rich fluids in the transport of economically important trace metals such as platinum-group elements. The hydrous minerals will be analyzed by electron probe, and whole rock analysis will be carried out by ICP. Results from this study should be applicable to other layered intrusions such as the Stillwater and the Bushveld.
