EAR-0447204GroveThe requested funds will be used to upgrade the MIT Experimental Petrology Laboratory. The Laboratory carries out experimental studies that provide information on the processes and time scales of chemical differentiation within the Earth and terrestrial planets. Studies involve both phase equilibrium and kinetic investigations. Projects include: experimental studies of the formation and chemical evolution of the Earth's continental crust, studies of the processes and Pressure - Temperature conditions of mantle melting in the Earth, moon and Mars, studies of the processes of core formation on Earth and Mars and of chemical differentiation and core formation on meteorite parent bodies. The upgrade will replace critical components that are necessary for the laboratory to continue productively and remain state-of-the-art. Funds are requested to carry out upgrades in three areas. 1) Upgrade outdated and failing temperature control equipment for furnaces used for externally heated gas pressure vessel, one-atmosphere and piston cylinder experiments. This equipment is failing and needs to be replaced with modern electronics. 2) Replace aging hydraulic equipment used to pressurize our three piston cylinder devices and upgrade the hydraulic systems. 3) Replace antiquated analytical balances and microscopes that are used in sample preparation and examination with up-to-date instrumentation. The acquisition of this new instrumentation will ensure continued efficient operation of the MIT experimental petrology laboratory, will allow the lab to sustain a high level of productivity and will allow us to continue to produce high-quality experimental results.

EAR-0447204格罗夫申请的资金将用于升级MIT实验岩石学实验室。该实验室进行实验研究，提供关于地球和类地行星内部化学差异的过程和时间尺度的信息。研究包括相平衡和动力学研究。项目包括：地球大陆地壳形成和化学演化的实验研究，地球、月球和火星地幔熔融过程和压温条件的研究，地球和火星核形成过程的研究，以及陨石母体的化学分异和核形成的研究。此次升级将替换实验室继续生产和保持最先进水平所必需的关键部件。需要资金在三个领域进行升级。1)对用于外热式气体压力容器、单气氛和活塞筒实验的加热炉的温度控制设备进行升级改造。这台设备出了故障，需要用现代电子设备来更换。2)更换用于给我们的三个活塞缸装置加压的老化液压设备，并对液压系统进行升级。3)用最新的仪器取代样品制备和检验中使用的过时的分析天平和显微镜。收购这一新仪器将确保麻省理工学院实验岩石学实验室继续高效运行，使实验室保持高水平的生产力，并使我们能够继续产生高质量的实验结果。
