项目摘要

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.

该奖项将资助莱斯大学地球科学系购买一台用于高压（P）-温度（T）实验研究的新型多砧装置。新购买的设备将成为莱斯大学实验岩石学小组活动的核心。该多砧装置目前是深部行星岩石学-地球化学和矿物物理学领域高研究的主力，可实现的压力范围为3-26 GPa，温度可达~3000 °C，也将成为海湾地区其他学术机构（包括休斯顿大学、德克萨斯农工大学和德克萨斯大学奥斯汀分校）了解地球深部过程和特性的窗口。 NSF 资助的研究主题将通过多砧实验立即解决，包括但不限于（1）地幔岩性（辉石岩、榴辉岩和橄榄岩）的部分熔融及其应用于板内玄武岩的生成，（2）俯冲带的脱挥发分和沉积物回收，（3）碳等挥发物的储存和运输地幔中的二氧化碳、水和卤素以及挥发物对地幔熔化和岩浆结晶的影响，以及（4）实验微量元素分配及其在火成岩成因中的应用。新获得的多砧装置将为莱斯大学实验岩石学研究小组提供的装置库增加显着的“深度”。莱斯大学实验岩石学小组的负责人达斯古普塔是一位职业生涯早期的科学家，因此增加多砧的提议将显着促进他的科学事业和解决地球深部过程一阶问题的能力。多个由 NSF 资助和 NSF 驱动的有关地球深部过程的科学项目将直接受益于多砧装置，并且多砧装置将立即用于许多学生研究项目。新多砧设施的全职技术人员将使仪器的安装、校准、记录、用户培训和操作顺利高效。
