Halogen Distribution in the Great Dyke, Zimbabwe

在大型层状侵入体中卤素的分布是 因为卤素的变化提供了关于 这些侵入体的脱气历史。 卤素分布 也为理解任何可能的作用提供证据， 富挥发性流体在输送经济上重要的 痕量金属如铂族元素。 这个项目 是观察含水相中的卤素， 富挥发性流体的运输， 重要的微量金属如铂族元素。 的 含水矿物将用电子探针分析， 岩石分析将通过ICP进行。 结果从这个 研究应该适用于其他分层入侵，例如 斯蒂尔沃特和布什维尔德

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.
