This project will advance knowledge of how fracture-controlled fluid flow at depth in the Earth influences the strength and mechanical behaviour of the crust, earthquake processes, and the formation of hydrothermal ore systems. Fundamental new knowledge of the dynamic variations in fluid transport properties and flow distribution in deep fracture networks also will have application for understanding hydrocarbon migration in fractured reservoirs, controls on seal integrity in geosequestration projects, and for geothermal energy production from hot, fractured rock. The project will develop international collaboration and train young scientists in applying multidisciplinary approaches to exploring fluid systems in the Earth's crust.

该项目将增进对地球深处受火山控制的流体流动如何影响地壳强度和力学行为、地震过程和热液矿石系统形成的认识。关于深层裂缝网络中流体输运特性和流量分布动态变化的基本新知识也将应用于理解裂缝储层中的油气运移、地质封存项目中密封完整性的控制以及热裂缝岩石的地热能生产。 该项目将发展国际合作，培训青年科学家运用多学科方法探索地壳中的流体系统。
