Acquisition of a Piston Cylinder Apparatus for Research in Experimental Petrology and Mineral Physics

活塞缸装置的收购将加强实验岩石学和矿物物理学研究在杰克逊地球科学学院（UT奥斯汀）。首先，研究将集中在俯冲带火山的更深根源。 重点将是在脱气的重要性富CO2流体从中间到中间岩浆，这些流体的溶解度的水和CO2在中间岩浆的影响，如何富CO2气泡的产生，以及如何挥发分和其他元素之间的分配富CO2流体和中间岩浆。 通过在受控条件下合成高质量的单晶和多晶样品，将加强对上地幔的矿物物理学研究。 这些晶体将用于金刚石压砧实验，以研究深部地幔中的碳酸盐和碳储存、上地幔和过渡带中的石榴石以及水化作用对橄榄石弹性性质的影响。 扩大研究能力与活塞缸将加强教育和培养研究生的实验研究，并丰富本科生的教育经验，通过他们参与本科研究项目。 这样的研究也将加强一些推广计划，包括UTeach和GeoFORCE在UT奥斯汀，能够证明活塞缸中学教师和学生在他们的暑期课程。

Acquisition of a Piston Cylinder Apparatus will enhance experimental petrology and mineral physics research in the Jackson School of Geosciences (UT Austin). First, research will focus on the deeper roots of subduction zone volcanoes. The focus will be on the importance of degassing of CO2-rich fluids from intermediate to silicic magma, how such fluids the impact on the solubility water and CO2 in intermediate magma, how CO2-rich bubbles are generated, and how volatiles and other elements partition between CO2-rich fluid and intermediate magma. Mineral physics research into the upper mantle will be enhanced by allowing high-quality, single and polycrystalline samples to be synthesized at controlled conditions. Those crystals will be used in diamond anvil cell experiments to research carbonates and carbon storage in the deep mantle, garnets in the upper mantle and transition zone, and the effects of hydration on the elastic properties of olivine. Expanding research capabilities with the Piston Cylinder will enhance the education and training of graduate students in experimental research, and enrich the educational experience of undergraduate students, through their involvement in undergraduate research projects. Such research will also enhance a number of outreach programs, including UTeach and GeoFORCE at UT Austin, by being able to demonstrate the Piston Cylinder to secondary school teachers and students during their summer programs.
