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

获得活塞缸装置将加强杰克逊地球科学学院（UT Austin）的实验岩石学和矿物物理学研究。首先，研究将集中在俯冲带火山的深层根源上。本文将重点讨论富二氧化碳流体从中间岩浆到硅质岩浆脱气的重要性，这些流体对中间岩浆中溶解度水和CO2的影响，富二氧化碳气泡是如何产生的，以及挥发物和其他元素如何在富二氧化碳流体和中间岩浆之间划分。通过允许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研究。这些晶体将用于金刚石砧细胞实验，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能的影响。扩大研究能力的活塞缸将加强教育和培养研究生的实验研究，并丰富教育经验的本科生，通过他们参与本科研究项目。这样的研究还将加强一些外展项目，包括德克萨斯大学奥斯汀分校的UTeach和GeoFORCE，通过能够在中学教师和学生的暑期课程中展示活塞缸。

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.
