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.

大层状侵入物中卤素的分布很有趣，因为卤素的变化提供了有关这些侵入物脱气历史的信息。 卤素分布还为了解富含挥发性流体在经济上重要的痕量金属（例如铂族元素）的运输中可能发挥的作用提供了证据。 该项目旨在研究水相中的卤素，以了解富含挥发性流体在经济上重要的痕量金属（例如铂族元素）运输中的作用。 含水矿物将采用电子探针进行分析，全岩分析将采用ICP进行。 这项研究的结果应该适用于其他层状侵入体，例如斯蒂尔沃特和布什维尔德。
