0842205CandelaThis proposal seeks funding of ~$69K to purchase components which will be used to upgrade and modernize the UMd TZM vessel/furnace assemblies and high-temperature magmatic-hydrothermal laboratory. For this request, the PIs intend to acquire components to construct four rapid-quench TZM vessel/furnace assemblies with low and high pressure gas lines and rapid cooling infrastructure, a Deltech furnace able to control temperature and maintain oxygen and sulfur fugacity, components to construct an automated temperature control system and data recorder system (for the TZM vessels), and upgrade other experimental equipment. UMd will provide approximately $30K in matching funds. The equipment acquisition, device fabrication and laboratory upgrades will enhance research in high temperature and pressure geology. Experimentation will include andesitic and dacitic melt-volatile phase-sufide mineral/melt equilibria, synthesis experiments for glasses and minerals at varying temperatures and pressures, and sulfide-silicate equilibrium studies at Earth surface pressure and at fixed oxygen and sulfur fugacities at temperatures up to 1700 °C. In addition studies will be undertaken to better understand ore metal partitioning between crystalline and melt phases, between melts and volatile phases, and between brines and vapors. Equilibria for these components and processes will be established. The laboratory and equipment upgrades will support a department with 25 full and part-time graduate students. Undergraduates are required to write thesis dissertations. Students will be incorporated throughout the research agenda and will co-author and present results. The PIs along with their students have an annual ?Maryland Day? where the public experiences their research work. The instrumentation will also be incorporated into the curriculum.***

0842205 Candela该提案寻求约6.9万美元的资金，用于购买将用于升级和现代化Umd TZM容器/熔炉组件和高温岩浆热液实验室的组件。对于这一请求，PI打算购买组件来构建四个快速淬火TZM容器/炉组件，包括低压和高压气体管线和快速冷却基础设施，一个能够控制温度并保持氧和硫逸度的Deltech炉，构建自动温度控制系统和数据记录系统（用于TZM容器）的组件，以及升级其他实验设备。UMD将提供大约3万美元的配套资金。设备购置、装置制造和实验室升级将加强高温高压地质研究。实验将包括安山岩和英安岩熔体-挥发相-硫化物矿物/熔体平衡、不同温度和压力下的玻璃和矿物合成实验以及在地球表面压力下和在高达1700 °C的温度下固定氧逸度和硫逸度的硫化物-硅酸盐平衡研究。此外，还将进行研究，以更好地了解矿石金属在结晶相和熔体相之间、熔体相和挥发相之间以及盐水和蒸汽之间的分配。将建立这些组成部分和进程的平衡。实验室和设备升级将支持一个拥有25名全职和兼职研究生的部门。本科生必须写毕业论文。学生将被纳入整个研究议程，并将共同作者和目前的结果。PI和他们的学生沿着有一个年度？马里兰州日？让公众体验他们的研究工作该工具也将纳入课程。*
