0345813MaroneSupport from this grant will facilitate construction of a custom-design biaxial deformation apparatus that will allow for fundamental studies of the behavior of earth materials at upper- to mid-crustal temperatures, pressures, and pore fluid conditions when subjected to fault zone stresses. Pressure vessels, a load frame, and hydrothermal control systems will be built in-house at Penn State using existing machine shop and electronics equipment and expertise. The system will be assembled by a dedicated technician within a two-year time period under the supervision of PI Chris Marone. Study of the properties of earth materials under realistic earthquake hypocentral conditions will greatly improve our understanding of earthquake fault rupture initiation processes. Relevant experimental data is sparse and successful development of this apparatus will add new empirical data to the field of rock mechanics. Experimental data that will be obtained with this device is highly complementary to planned in situ observation of the mechanical and physical environment experienced by San Andreas fault zone materials (i.e., the SAFOD drilling project).***

0345813Marone 这笔赠款的支持将促进定制设计的双轴变形装置的建造，该装置将允许对地球材料在受到断层带应力时在上中地壳温度、压力和孔隙流体条件下的行为进行基础研究。 压力容器、负载框架和水热控制系统将利用现有的机械车间、电子设备和专业知识在宾夕法尼亚州立大学内部建造。 该系统将由专门的技术人员在 PI Chris Marone 的监督下在两年内组装完成。 研究现实地震震源条件下地球材料的特性将极大地提高我们对地震断层破裂萌生过程的理解。 相关实验数据较少，该装置的研制成功将为岩石力学领域增添新的经验数据。 通过该设备获得的实验数据与计划对圣安德烈亚斯断层带材料所经历的机械和物理环境进行的现场观测（即 SAFOD 钻探项目）具有高度互补性。***
