Acquisition of a Walker-style multi-anvil device for high pressure-temperature petrology and geochemistry research.

该奖项将资助赖斯大学地球科学系购买一种新的多砧装置，用于高压（P）-温度（T）实验研究。新获得的设备将作为赖斯实验岩石学小组活动的核心。多砧装置目前是深层行星岩石学-地球化学和矿物物理学领域高水平研究的主力，可实现的压力范围为3-26 GPa，温度约为3000 °C，它还将成为海湾地区其他学术机构了解深层地球过程和性质的窗口，包括休斯顿大学、得克萨斯农工大学和得克萨斯大学奥斯汀分校。美国国家科学基金会资助的研究主题将立即通过多砧实验解决，包括但不限于：（1）地幔岩性的部分熔融（辉石岩、榴辉岩和橄榄岩）与板内玄武岩生成的应用，（2）俯冲带中的脱挥发分作用和沉积物再循环，（3）挥发物如二氧化碳、水和卤素的研究以及挥发分对地幔熔融和岩浆结晶的影响;（4）微量元素配分实验及其在火成岩成因中的应用。新获得的多砧装置将增加一个显着的“深度”，以设备的剧目提供给实验岩石学研究小组在赖斯。赖斯实验岩石学小组的领导人Dasgupta是一位早期职业科学家，因此建议增加多砧将大大推进他的科学生涯和他解决地球深部过程一阶问题的能力。由国家科学基金会资助和推动的几个关于地球深部过程的科学项目将直接受益于多砧装置，多砧装置将立即用于许多学生研究项目。新的多砧设施的全职技术人员将能够顺利和有效地安装，校准，文档，用户培训和仪器操作。

This award will fund the acquisition of a new multi-anvil apparatus for high pressure (P) - temperature (T) experimental research in the Earth Science Department of Rice University. The newly acquired device will serve as a centerpiece of activities for the experimental petrology group at Rice. The multi-anvil device, which currently serves as the workhorse of high-research in the field of deep planetary petrology-geochemistry and mineral physics with achievable pressure range of 3-26 GPa and temperature to ~3000 °C, will also serve as a window to the deep Earth processes and properties for the other academic institutions in the Gulf area including University of Houston, Texas A&M University, and University of Texas at Austin. The NSF funded research themes that will immediately be addressed through multi-anvil experiments include, but not limited to, (1) partial melting of mantle lithologies (pyroxenite, eclogite, and peridotite) with application to generation of intraplate basalts, (2) devolatilization and sediment recycling in subduction zones, (3) storage and transport of volatiles such as carbon dioxide, water, and halogens in the Earth's mantle and the effects of volatiles on mantle melting and magma crystallization, and (4) experimental trace element partitioning with application to igneous petrogenesis. The newly acquired multi-anvil device will add a significant "depth" to the repertoire of devices available to the experimental petrology research group at Rice. The leader of the experimental petrology group at Rice, Dasgupta, is an early-career scientist, thus the proposed addition of a multi-anvil will significantly advance his scientific career and his ability to tackle first order problems on deep Earth processes. Several NSF-funded and NSF-driven science projects on deep Earth processes would directly benefit from the multi-anvil device and the multi-anvil will immediately be used for many student research projects. A full-time technician of the new multi-anvil facility will enable smooth and efficient installation, calibration, documentation, user training, and operation of the instrument.
