Ripley 9417687 This pilot project will study processes involved in the development of hydrothermal flow systems associated with continental rift-related magmatism. The project will emphasize stable and radiogenic isotopic studies of volcanics and related hypabyssal rocks associated with the Duluth Complex in northeastern Minnesota. Results will contribute to an understanding of possible origins of platinum group element mineralization in the Duluth complex, and will lead to a better understanding of crust-magma interaction in rifting environments.

Ripley 9417687 该试点项目将研究与大陆裂谷相关的岩浆作用相关的热液流系统的发展过程。 该项目将重点对与明尼苏达州东北部德卢斯杂岩有关的火山岩和相关浅成岩进行稳定和放射性同位素研究。 结果将有助于了解德卢斯杂岩中铂族元素矿化的可能起源，并将有助于更好地了解裂谷环境中的地壳-岩浆相互作用。
