EAR-0236564HammerThis experimental facility will allow exploration of magmatic processes at high temperature and pressure to 5 kbar. Traditional methods of phase equilibria research developed by igneous and metamorphic petrologists will be enhanced and adapted using technical advances such as rapid quenching and automated control of pressure to solve volcanological problems. Experimental studies will explore eruption parameters and test hypotheses about volcanic plumbing systems and magmatic processes on Earth and other planets. Dynamic experiments, particularly those in which pressure is varied, are vital to understanding how magmas respond chemically to changes in intensive parameters and volatile concentrations prior to and during volcanic eruptions. The long-term objective is to contribute to the growing database of all the relevant parameters necessary to quantitatively model the timing, style, and intensity of volcanic eruptions. One broader impact of the scientific results will be an improved understanding of hazards associated with volcanic eruptions. The laboratory is expected to serve a regional community of volcanologists in Hawaii and Pacific region, through collaborations with USGS scientists and university researchers. The University of Hawaii is a magnet for graduate students in volcanology, many of whom will be exposed to laboratory research through courses and work toward advanced degrees in the MS/PhD program.***

EAR-0236564Hammer 该实验设施将允许在 5 kbar 的高温和压力下探索岩浆过程。 火成岩和变质岩石学家开发的相平衡研究的传统方法将利用快速淬火和压力自动控制等技术进步得到加强和调整，以解决火山学问题。 实验研究将探索喷发参数并测试有关地球和其他行星上的火山管道系统和岩浆过程的假设。 动态实验，特别是压力变化的实验，对于了解火山喷发前和喷发期间岩浆如何对强度参数和挥发性浓度的变化做出化学反应至关重要。 长期目标是为不断增长的所有相关参数数据库做出贡献，以定量模拟火山喷发的时间、类型和强度。科学成果的一个更广泛的影响将是加深对火山喷发相关危害的了解。 该实验室预计通过与美国地质勘探局科学家和大学研究人员的合作，为夏威夷和太平洋地区的火山学家社区提供服务。 夏威夷大学对火山学研究生有着巨大的吸引力，其中许多人将通过课程接触实验室研究，并在硕士/博士课程中攻读高级学位。***
