Time- and Temperature-Dependence of the Fluid Transport Properties, Strength and Mechanical Behaviour of Crustal Faults - An Experimental and Modelling Study

高温岩石变形实验将与高分辨率计算机辅助X射线显微断层摄影术一起进行，以确定在热液环境中模拟断层岩的滑动和震间愈合期间对流体输运性质、强度和机械行为的时间依赖性和温度依赖性影响。研究结果将与元胞自动机建模方法一起使用，以定量了解流体流动和岩石变形之间的耦合如何控制大陆孕震机制中断层网络中的地震破裂和流体迁移。 这项工作将为地震成核的触发和矿床定位的控制提供新的认识。

High temperature rock deformation experiments will be performed in conjunction with high resolution, computer-aided x-ray microtomography to determine time-dependent and temperature-dependent effects on fluid transport properties, strength and mechanical behaviour during slip and interseismic healing of simulated fault rocks in hydrothermal environments. The results will be used with cellular automaton modelling approaches to develop a quantitative understanding of how coupling between fluid flow and rock deformation controls earthquake rupture and fluid migration in fault networks in the continental seismogenic regime. This work will provide new understanding of triggers for earthquake nucleation and controls on localisation of ore deposits.
