3-D Dynamics of the Ferrar Magmatic Mush Column, McMurdo Dry Valleys, Antarctic

该奖项支持南极洲麦克默多干谷费拉尔岩浆系统的研究。它的目标是了解岩浆的运输和分化，大陆地壳和火山岩浆形成的主要过程，以及行星和陨石母体分化的关键方式。旧的模型设想了吸管和熔化液体的房间，这些液体通过一场水晶雨聚集和分化。这一观点受到了干谷的挑战，在干谷中，数千万年的侵蚀形成了深深的切割山谷，横切了一个巨大的岩浆体。岩浆体的深处暴露出堆叠的、充满晶体的岩床，这表明岩浆作用比以前认为的要复杂得多。这个项目正在破译这些窗台上记录的复杂过程。这项工作的更广泛影响包括本科生和研究生教育，博物馆展览的贡献，更广泛的公众讲座，以及在一本书中传播结果。

This award supports studies of the Ferrar magma system in the McMurdo Dry Valleys of Antarctica. Its goal is to understand magma transport and differentiation, the primary processes by which continental crust and volcanic magmas form, as well as a key way that planets and meteorite parent bodies differentiate. The old model envisions straws and chambers of molten liquid that pond and differentiate through a rain of crystals. This view has been challenged by the Dry Valleys, where deeply incised valleys produced by tens of millions of years of erosion crosscut an enormous magma body. Deep recesses of the magma body expose stacked, crystal-laden sills that indicate much more complex magmatic processing than previously thought. This project is deciphering the complex processes recorded in these sills.The broader impacts of this work include undergraduate and graduate student education, contributions to museum exhibits, lectures for the broader public, and dissemination of the results in a book.
