Chapman Conference on Shallow Level Processes in Ocean Island Magmatism: Distinguishing Mantle and Crustal Signatures

该奖项将帮助四名研究生参加明年11月在加那利群岛举行的AGU查普曼会议。最近的一些研究表明，洋岛玄武岩的地壳改造可能是相当普遍的。接下来的问题是，地壳污染是否仅仅是影响原本强健的地幔特征的噪音，或者目前归属于地幔储层的特征是否反映了地壳和地幔输入的某种组合。会议将从若干角度处理这个问题。提出了四个广泛的讨论主题，希望能与会议四天的重点相对应。它们是：1；化学地球动力学科学的发展状况，如通过对海洋岩浆的研究确定的。2. 洋岛岩浆活动的压力-温度-时间约束。3. 岩浆-地壳相互作用的物理过程。4. 岩浆-地壳相互作用的地球化学。

A number of recent studies have shown that crustal modification of ocean island basalts may be quite common. the question that then arises is whether crustal contamination is simply noise affecting otherwise robust mantle signatures, or whether the characteristics currently attributed to mantle reservoirs reflect some combination of crustal and mantle input. The Conference will address this question from a number of perspectives. Four broad discussion subjects have been proposed, which will hopefully correspond to four days of focus at the meeting. They are: 1. The state of the science in chemical geodynamics, as determined from studies of oceanic magmas. 2. The pressure-temperature-time constraints on ocean island magmatism. 3. The physical process of magma-crust interaction. 4. The geochemistry of magma-crust interaction.
