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. ***

0824908Zhu 本提案寻求资金购买三轴测试装置，用于测量地壳压力和温度下岩石超声速度、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。要求的是新英格兰研究 AutoLab 1500，这是最便宜的商业选择（考虑到他们的学术折扣）。许多基本的地球科学问题依赖于对地壳温度和压力下流体饱和岩石的起源、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、渗透性、电导率和孔隙率）和机械（摩擦、强度）特性进行实验室研究的需求。拟议设备支持的具体项目是 1) NanTroSEIZE ？由 IODP 指导的日本西南部俯冲带跨学科研究，2) SAFOD ？研究的一个组成部分，其中将确定断层岩石的地球物理和地球化学性质，以及 3) 台湾车龙埔断层钻探项目？其中一个组成部分将为乡村、损伤和断层核心区域的岩石地球物理分析提供样本。 PI 通过 NSF-EAR、其他 NSF 部门和其他联邦机构获得了大量研究经费。该设备将安置在已分配的 500 平方英尺的房间内。地质部已承诺提供支持（机械车间服务、电力、水和压缩空气）。 PI 将安装并操作该设备。 PI 将培训研究生和本科生、博士后和其他用户。外部用户将为在设备上进行的实验提供材料和消耗品。三轴测试装置将支持马里兰大学的研究和培训。来自 UMd 和其他机构的研究生以及与 PI 进行过多次合作的其他外部研究人员将受到接待。该设备将被纳入本科生高级论文中。将纳入行业合作伙伴，为学生提供潜在的就业机会。 ***
