0824908Zhu本提案寻求资金，以购买一台三轴测试设备，用于测量岩石在地壳压力和温度下的超声波速度、渗透率、电阻率和声发射活动。所要求的设备将针对中等压力（高达150 MPa）和温度（高达150 ° C）性能进行优化。要求是一个新英格兰研究自动实验室1500这是最便宜的商业选择（考虑到他们的学术折扣）。许多基础地球科学问题依赖于对流体饱和岩石在地壳温度和压力下的起源、成分、变形机制、物理性质和摩擦行为的透彻理解。深钻项目增加了对沉积岩输运（地震速度、渗透率、电导率和孔隙度）和机械（摩擦力、强度）特性进行实验室研究的需求。具体的项目将支持拟议的设备是1）NanTroSEIZE？由IODP指导的日本西南俯冲带跨学科研究，2）SAFOD？断层岩的地球物理和地球化学性质的研究的一个组成部分，将确定; 3）台湾车笼埔断层钻探计划？其中一部分将提供样品，用于对乡村、损坏和断层核心地带的岩石进行地球物理分析。PI通过NSF-2000、其他NSF部门和其他联邦机构获得了相当多的研究资金。该设备将被安置在一个500平方英尺的房间已经分配。地质部已承诺提供支助（机械车间服务、电力、水和压缩空气）。PI将安装和操作器械。PI将培训研究生和本科生，博士后和其他用户。外部用户将为在该设备上进行的实验提供材料和消耗品。三轴测试设备将支持UMD的研究和培训。来自UMD和其他机构的研究生将被接待，以及PI与之有许多合作的其他外部研究人员。该设备将被纳入本科毕业论文。一个行业合作伙伴将被纳入学生接触潜在的就业机会。***

0824908Zhu This proposal seeks funding to purchase a triaxial testing device for measuring rock ultrasonic velocity, permeability, electrical resistivity and acoustic emission activity at crustal pressures and temperatures. The requested apparatus will be optimized for moderate pressure (up to 150 MPa) and temperature (up to 150 °C) performance. Requested is a New England Research AutoLab 1500 which is the least expensive commercial option (given their academic discount). Many fundamental Geoscience questions rely on a thorough understanding of origin, composition, deformation mechanisms, physical properties, and frictional behavior of fluid-saturated rocks under crustal temperatures and pressures. Deep drilling projects have heightened the need for laboratory studies into sedimentary rock transport (seismic velocity, permeability, conductivity, and porosity) and mechanical (friction, strength) properties. Specific projects to be supported by the proposed apparatus are 1) NanTroSEIZE ? a Southwest Japan subduction zone interdisciplinary study directed by the IODP, 2) SAFOD ? a component of study in which geophysical and geochemical properties of fault rocks will be determined, and 3) The Taiwan Chelungpu-fault Drilling Project ? a component of which will provide samples for geophysical analysis of rocks in country, damage and fault core zones. The PI has considerable research funding through NSF-EAR, other NSF divisions and other federal agencies. The apparatus will be housed in a 500 ft2 room already allocated. The Department of Geology has pledged support (machine shop service, electricity, water and compressed air). The PI will install and operate the device. The PI will train graduate and undergraduate students, postdocs and other users. Outside users will fund materials and expendables for experiments performed on the apparatus. The triaxial testing device will support research and training at UMd. Graduate students from UMd and other institutions will be hosted as well other outside researchers with which the PI has numerous collaborations. The device will be incorporated into undergraduate senior theses. An industry partner will be incorporated to expose students to potential employment opportunities. ***
